Open thread: questions and explanations
Over on the T-urf13 thread we had a request for an open thread for questions and answers. In the spirit of the holiday season, I'm happy to oblige. However, let's make this an experiment in attempting to increase the signal-to-noise ratio in blog comments. I suggest:
1. This thread is not for arguing, it is for explaining.
2. Thus the issue is not whether or not person X believes viewpoint Y, the only issue is to understand/explain the science relating to Y.
3. Typically, these will be about evolution, but I imagine some people may have itching questions about climate science, given the recent denialgasm that's been going on in the wingnut-o-sphere, found in some its most extreme, pitchforks-and-torches forms on the blogs of the Discovery Institute (there goes Casey Luskin's attempt at pro-environment credibility, by the way) and William Dembski
4. Don't insult honest questioners who come to the thread. Give people the benefit of the doubt.
5. Questioners: don't take statements like "you really aren't getting it" as insults, and don't take "you need to read this reference" as a brush-off -- learning requires effort and looking stuff up, particularly learning complicated science-y stuff.
6. I will delete noncompliant posts in a fairly arbitrary and dictatorial manner, and I will take suggestions, since I don't have time to monitor the thread constantly.
Like I said, this is an experiment -- go to it!

What's a good way to keep straight in my mind the differences between mice, rats, voles, moles, shrews, tenrecs, lemmings, and all the other rodents and rodent-like mammals?

I want to know which of the mutually contradictory anti-evolution positions (young earth, old-earth-young-life, old life without common descent, old life with common descent, etc.) is the "correct" one. I want only anti-evolutionists to answer, so if you think they're all wrong, please explain that elsewhere. I would especially like advocates of each anti-evolution position to tell me why the others all fail.
Most anti-evolutionists these days claim that "Darwinism" is wrong by focusing on (some of the) evidence, and not because some book says so, so you should be able to do the same with supporting your position, and refuting other anti-evolution positions.

Why haven't the science defenders around here written a single criticism of climate scientists who have thwarted FOIA requests by "losing" their data?

Nick,
Please feel free to delete this as well as chunkdz's comment, but The Sensuous Curmudgeon has written extensively on "Climategate," and not to defend anyone. Ronald Bailey (long time ID/creationism critic) has also weighed in. And I have not even tried to google it as chunkdz and any lurker can do. Only in the DI's fantasy are scientists "silent" on it.

Frank, my question was about Panda's Thumbs silence in particular.

Regarding the hacked emails and climate scientists:
Since this is a blog concerning life sciences, I am going to guess that folks here don't feel qualified to address the specific issues. However, the site Realclimate (realclimate.org) is fielding questions on this topic. (hundreds of questions, last I looked) Since these are climatologists doing the discussing, you might find your answers there.

In Dawkins' "The Blind Watchmaker", he has a chapter about how replicating chemical reactions could have been a precursor to RNA molecules. In the chapter he talks alot about certain clays being important for the initial chemical reactions.
My experience with clays is only in the context of soil particle size relative to other soil particles (ie, sand, silt, and clay). Is Dawkins using the same definition I am thinking of or something different? How realistic is his scenario?

I have seen one thing from Panda's Thumb, and that is comments on the personal nature of emails and the violation that occurred. However, the people who actually wrote some of those emails, as well as those who were part of the discussions those emails pertained to, are better equipped to discuss them, especially since it appears that they were edited, taken out of context, or misinterpreted. Some of these scientists are the ones actually fielding the questions on realclimate.
Posters at the Panda's Thumb indeed defend the integrity of science against those who would misinform the public regarding biological evolution, usually for religious reasons. Most areas of science are not attacked in this way. This site attracts people who actually know the field well. They are prudent, however, in not making any statements regarding this event and its fallout; the area of science is not the same, and the emails are part of a much bigger picture, a picture that has been distorted for political reasons by the cherry-picking of content. Only the folks directly involved should be answering these claims. If anyone has been dishonest other climate scientists will be able to ascertain this. Unless, of course, folks believe that science is one big conspiracy. (which would be unlikely-that would require an awful lot of scientists to cooperate on so many levels, and like any group of people, they would fail spectacularly)

Hey, I have itching questions about ClimateGate, but I was never a ___ (fill in the blank with all those goofy terms you used in the attempt to shut down the debate). Really, with those expressions (denialgasm, wingnut-o-sphere, pitchforks), you're trying to get real scientists who want to speak out against ClimateGate to shut up.

Re: climate change -- we at PT are not particularly nerds on this topic. I have actually spent a fair amount of time reading about it lately, but it gets complicated fast, and other bloggers are doing stuff better than I could do without a lot of work.
One question I have on this is the following: once you wade through the vast amount of crap spewed by Egnor and the wingnuts, what remains appears to be a question about how/why some tree-ring datasets seem to match up with direct temperature measurements from up until 1960, but not so much after. Far from being hidden, this is discussed directly in the 2007 IPCC report.
My questions, since I haven't found a handy explanation yet:
1. Apparently only some of the tree-ring datasets show this -- which ones? (Also, people like me don't innately know what "stripbark" means -- although I've figured that one out, explain similar terminology for treering datasets if possible.)
2. Why the divergence after 1960, if known, and what significance does it have to the big picture, if any?
3. Just how much uncertainty does the divergence problem add to:
* a statement like "the climate has warmed over the last 50 years"
* the climate over the last 10 years is likely warmer than natural variability over the last (say) few thousand years

1) This blog is not about "the integrity of science", broadly defined. No-one but you said it was. This is obviously a blog that focuses on evolutionary biology. That's obvious. There are plenty of climate science focused blogs.
2) Individual scientists in all fields commit ethical lapses at times. So do individual professionals in all other professional fields. Scientists are perhaps more likely to be caught, as others may try to replicate their results.
Ethical lapses by individual scientists do not negate strong bodies of scientific evidence.
Furthermore, we must greet accusations against individual scientists with skepticism, until they are definitively shown to have merit.

In regards to the organ question. What we do know about development at this point seems to suggest that these sorts of things are possible. To my knowledge however we don't have enough of the exact details down to run an evolutionary pathway analysis. These experiments have been done for some simple molecular systems where all of the mutants between two different points are created and measured for fitness. These experiments have reinforced that there are pathways that can be traversed by natural selection, but also eliminated many others.

I recently read Dr. Dembski's book "The End of Christianity" and i just wanted to share one of my favorite exerts from it. I am just getting into the whole evolution vs Intelligent design or creation, so this is all so interesting to me. I loved how this book talks about the natural evils of life. It does an excellent job of explain it.
It reads:
Poised between the Garden of Eden and the future Paradise, we can be like fugitives stranded in a no-man's land without a sense of purpose. We know of a primordial state of bliss we lost and of a perfected state of bliss toward which we are moving, but in the meantime we are here, on this earth with its perplexing mix of beauty and tragedy.
This reminded me that we are all here for such a short time and it is what we do here on Earth with the time we are given that counts.
The book goes on to say:
Though banished from the Garden with its gate forever barred, the memory of that perfect union with God keeps alive the hope of Paradise. When we let that memory fade, this earth is a place of exile. But when we remember that the divine image is in each of us, this earth becomes an arena of purpose. Then our vision is liberated. The divine images in all of us shine and collectively illumine the way- a way of purpose. What is the divine image that generates purpose? God, the Divine, is Love. Thus our divine image, our defining feature, is love.
I really hope that you enjoyed this exert as much as I did. Weather you are a believer or not, you should be challenged by this. It was a great reminder to me.

My question to the PT group (and one I've asked elsewhere)...
Is ID dead?
By that, I mean has ID creationism run its course as a means to circumvent the SCOTUS ruling against creationism in public school science classes? Scientifically, IDC was stillborn and has never shown any signs of life, and politically it seems the creationist crusade on the public schools has already moved on to the next strategy, i.e. "academic freedom" and "strengths and weaknesses of evolution".
One of the ways I measure IDC's activity is via this blog. When ID creationists were actively pushing for IDC's inclusion in public school science curricula, the PandasThumb was a virtual beehive of activity, with new entries on IDC almost every day.
Now? The PT is mostly about "Hey, look what Dembski/Luskin/Egnor/Behe said on this website", pictures, and updates on the Freshwater case. As far as actually combating IDC's efforts to invade the public schools, judging by this site one could argue that that particular battle is over (at least for the moment).
Of course IDC lives on in the public mind as a vague reference to Goddidit, but is there any other way in which IDC can be considered to be "alive"?
Frank J · 1 December 2009

Chunkdz,
My understanding of the climate emails is that the didn't "destroy data" (as in the data no longer exists), but they deleted emails to avoid having them become part of a FOIA request. The two are not the same. And as a government scientist, if the latter turns out to be true, it's simply something you cannot do under any circumstances.
phantomreader42 · 1 December 2009
So, John, do you admit that ID is purely religious and utterly devoid of scientific merit (as demonstrated by the admitted religoius motivations of prominent cdesign proponentsists and their total failure to support their claims through experiment or evidence)? If not, can you be the first IDiot in the history of the planet to actually show us some scientifically valid evidence for ID?
Richard Simons · 1 December 2009
Kevin (aka OgreMkV) · 1 December 2009
Tell you guys what. Why don't you go to the NASA GISS site and use their data and develop a model that you then make totally public (including the source code) and run your sims and then publish the results in a peer-reviewed journal.
Heck, you might (and I say MIGHT) be able to use excel to examine the trends.
Then you're doing science. Hacking an e-mail server is not science. Screaming about the ethics of science because of something that may or may not have occured (I mean, why delete the e-mails with data, yet leave the e-mail that says "delete those e-mails") is not science.
Comon, go do it. Publish the results.
Oh, BTW, anyone have a tool that uses ID to predict results of population experiments?
chunkdz · 1 December 2009
Kevin (aka OgreMkV) · 1 December 2009
I don't know why. Here's the data:
http://data.giss.nasa.gov/gistemp/
The data available includes the global-mean monthly,seasonal,zonal and hemisphere data from both met-stations and land-ocean temperature index (whatever that is).
It took my about 5 minutes to import the text file to Excel and generate a chart. I only did Jan for each year listed (1880-2009), but anyone with half an interest in this could do it themselves.
I'll also point out that the model NASA uses can be downloaded as source code so you can make whatever changes you want.
Here's the source pages to the articles used.
http://data.giss.nasa.gov/gistemp/references.html
This includes several articles on historical climate data and how to analyze climate data.
Alternately you could go here:
http://www.ncdc.noaa.gov/oa/mpp/freedata.html
In spite of the name, much of the data is not free for download, but a decent researcher wouldn't mind paying US$80 for 1697-present Surface Data for the Global Historical Climate Network. (I guess those thousands of weather stations cost some bucks to install huh?)
There it is. Go for it. You do the math, you publish your source code and then let's all take a look at your results. Please. We're begging you to do science here... instead of bitching about how we do it, you try it.

The rest is still in private hands and is not allowed to be publically released because of the dollar value of the data.

For someone who is such a devout "Christian" like Dembski, can he - or indeed anyone - excuse him for his reprehensible behavior, which includes not only what you mentioned, but also a blatant attempt at censorship against me over at Amazon.com, and, more importantly, all but admitting that he stole a Harvard University cell animation video that was produced for one of Harvard's biological science departments by the CT-based scientific animation firm XVIVO (I will remind others that we have to thank science blogger Abbie Smith for her excellent detective work, which forced Dembski to all but admit that he had stolen the video from Harvard.).
Therefore, in light of what you and I have said regarding Dembski's reprehensible behavior, no one should feel sorry for Dembski for having an autistic child. It's merely the least that the Almighty could do to Dembski for not measuring up to Christ's standards, but instead, acting like the servant of Lucifer that he most certainly is.

ID is approximately as dead as "creation science" claims that evidence supports a 6000 year old earth and global flood, as far as public school curricula are concerned.
Only a theocratic coup could get it into public schools now, and if that happened, there would be no need for watered-down stealth creationism anyway.
However, it's still excellent for routine moronstream media claims that "some 'scientists' doubt evolution", pompous letters to the editors of newspapers from small town lawyers, drunken confrontations at parties, angry blog posts by self-styled "geniuses" with low level comp sci degrees who "know" that they know more about "information" than all biomedical scientists (including the many who are cross-trained in math and comp sci), etc.

What follows is strictly my own personal opinion, do not impute it to others.
You must obey your right wing masters, for whatever reason.
They need the support of the racists and religious fanatics, so they deny evolution. This is true even in the unlikely event that you are neither a racist nor a religious fanatic.
Paradoxically, they also seek to please the fossil fuels industry, a high-tech industry grounded in mainstream geology. Contradiction? No problem. Simply deny another major batch of scientific data, that which supports the rather intuitive conclusion that when humans pump a lot of CO2, from formerly sequestered sources, into the atmosphere, in a short time, it may contribute to climate change.

Who says they believe in the necessity of a supernatural designer?

Just proves my point -- that maybe ID need not be religious.
"Apparently, you seem to be implying that if an idea is “supported” by two self-proclaimed agnostics, that over-rules its obvious religious motivation, funding, and associations."
Nope, not implying that. I know that many ID supporters, nay most, wish you'd graduate from "designer" to "Jesus". I'm challenging the claim that ID is /inherently/ religious, and I'm using these two men as support for that idea. By the way, Bradley Monton is an atheist, not an agnostic. I should've stated that.

Deleted emails, destroyed data, and politicizing dissent are relevant to transparency,
you haven't the slightest clue what you're talking about.

you must have completely ignored the part where the data is already published, aside from the fact that it is indeed only one sample we are speaking of amongst many.
this is very much sounding like the damn obama birth certificate argument.
he's published his actual birth certificate, but it's not the original one the hospital gave his mother, but a state copy, ergo there is no "transparency". :P
you guys invent conspiracies where there are none.
you entirely ignored the fact regardless of whether even an entire original dataset was lost, the data WAS published already, did undergo peer review etc. it's not like the data, even in that specific, one, instance, never existed.
you guys are complete, utter, morons.

paper trail wise, it is exactly the same as throwing out a returned check from the bank.
the bank recorded and verified the data on the check before sending it back to you, just as the data we are talking about was recorded, used, verified, and published by a scientific journal.
not tossing out the check is always a nice safeguard, but it simply isn't necessary... unless you think the all banks are continually participating in a global conspiracy to alter the value of every check ever submitted.
you, uh don't think that, do you?

But then, totally disregarding the stated purpose of the thread, somebody upCHUNKed and the dreary axe-grinding proceeded.

I think the ID/Creationist crowd simply thinks that if the Bible says it, then it must be the best way. Their intentions, not disguised in anyway, is to make the US a theocratic state... just like Iran. [This includes the removal of the US Constitution and the Bill of Rights.]
They believe that their way is the only way and that everyone should do like they want. Your beliefs do not matter. Your beliefs are not relevent. And your beliefs are wrong (unless you agree with them 100%).
As best as I can figure, they really believe that reality is determined by consensus and he who is most unwavering wins. Therefore, his reality is true.
I'd laugh my tail off about it, but I'm stuck on the same planet as these clowns. Unfortunately, most of them are also on my continent and on the school board in my state.

As far as I know, nobody has tried to recreate life itself in a lab from scratch. What usually happens is that scientists try to simulate a specific model for how the pre-cursors to life might develop chemically.
All that said, if somewhere out there a new form of Earth life is springing into being, whether in the lab or under a rock, that doesn't share any inherited genetic material with the life we already know, that would be extremely significant for our knowledge of how life arises, the chance for live elsewhere in the universe, what constitutes living vs. non-living things, and how biology in general works. What I often see lamented in books about the Universe at large is the fact that we only have one kind of life to consider when asking questions about extraterrestrials, and that life is Earth Life with its universal common ancestry.

OK, another legit question. Someone, in this thread or another, referred to the folding up of DNA strands within the nucleus. It's been a looong time since Bio 101, so here are some embarrassingly basic questions.
Is each chromosome a single strand of DNA, all scrunched up? If I'm not mistaken, the actual chromosomes only form at the time of cell division. At other times, the DNA is unraveled so it can do its template work, correct? But in the non-chromosome state, it's still all wadded up in the nucleus. Is it wadded into a particular necessary pattern, or just random, like a mass of spaghetti? If the complex 3-D pattern of the tangled mass is non-random, then is the pattern necessary for the proper functioning? Say if 2 areas widely separated linearly on a strand are shoved together in the "mass", does that allow them to interact in ways that they couldn't otherwise? I believe I've seen color-coded diagrams of gene locations that looked like parts of the gene were widely separated on the strand. Does the folding-up of the strand allow them to come into contact and thus work together? And I assume strands from other chromosomes are all mixed together--or are they somehow segregated? And if they are mixed together, is there a pattern, or is that random? And if there is a pattern, is that significant to their function (is it necessary for different strands to get together for something)?
And if this is all completely off-base and a total crock, I'll appreciate that answer too. Then I'll be a little less crocked.

Coincidentally, while debating someone on another venue about the "climategate" thing, I was confronted by the writings of one Roy Spencer, who is (in addition to a AGW denier) an ID advocate. In addition to pointing out his lack of peer-reviewed work (not editorials or vanity papers hosted on his own site) significantly challenging the consensus, I said he also has a problem understanding how science works because he thinks "evolutionism" is on equal scientific and philosophical footing as ID. I got a retort saying it was irrelevant and that Spencer was right about it anyhow, so I explained that I consider it a litmus test on scientific literacy for people who claim, like Spencer, to have read up on the relevant subjects.
I figure a lot of PTers might have a similar opinion to mine on the subject, but is it acceptable to bring up such things during the course of arguing about the consensus of climate change and the "deniers," or entirely inappropriate because he was speaking outside of his field?

Since, this is about religion, let me ask a question. Have you or any fundamentalist christian that you know explored any other religion, or science, or philosophy beyond your own to its fullest?
Have you studied the manuscripts and looked at the texts, evidence, and/or beliefs of any science, religion, or philosophy that is not your own?
Or, do you believe that most other ways of thinking simply are wrong because they are different than yours?
If so, wouldn't this be the only argument that you use?
Concerning the fact that Fundamentalist Christians do not think or reason, they simply have faith. Which is exactly the entire point. They do not (in general) think or reason.
Would this not be the same thing atheists and evolutionist do just on the opposite end of the spectrum? And thinking Christians too, but yes
If Jesus is right in what he said, then he really is the Son of God and he is the only way to heaven. There would be a heaven and there would be a hell. That's a mighty big IF to want to kill thousands of homosexuals, pagans, and scientists because they are anathema to your Christian philosophy

In my experience, no. In my experience most people believe in their religion because of the way that they were raised or as a matter of personal lifestyle. Very few religious beliefs are based on evidence. Some may be based on personal experiences, but that is not the same thing.
The only valid reason to believe in evolution is because of the evidence. There really is no other reason to believe it. It does not fit with any personal lifestyle choices. It does not give you the freedom to disregard the law or behave immorally. It doesn't mean that you have to give up any religious beliefs, except possibly those that conflict with reality. And it is not usually what you were raised with. In my experience, it is a position that is reached after carefully considering the evidence, usually within the setting of higher education.
As for atheism, I actually don't know that many people who identify themselves as atheists, most who do not have any religious beliefs would probably use the label agostic. In my experience, the most common reason why people lose their faith or belief in God is because of the dishonesty and hypocricy of religious people who deny reality. In fact, I suppose that this is a major reason for the recent decline in organized religion in the United States.
In my experience, many people often use their religious beliefs to justify all types of immoral behavior. That is a real turn off to those who are honestly searching for truth amd meaning in their lives.

Wow. 150+ comments and unless I missed 1 or 2, I see that no long time (e.g. FL) or new (e.g. Steve P.) PT anti-evolutionist has shown up to support their own alternative on its own merits. I long suspected that they had little confidence in their own "theories" but this silence really shouts it.
Maybe if I make it easier, and limit my question to a specific question regarding human origins, they might stop "expelling" themselves. My question is, which of these fossils do you think is of the human "kind" and which is of the ape "kind"? Or do you agree with Michael Behe who thinks they are all one "kind," along with dogs, cats and broccoli?

Here's one:
Reading microcosm got me wondering: when looking at genetic similarities between organisms, how does the geneticist distinguish between similarities because of descent from similarities because of lateral gene transfer? I can guess that basic functional genes are mostly likely inherited, but is there a 'grey area' where it's hard to tell whether material is inherited or has been donated? Especially since the donated material ends up being passed down too, dunnit?
DS · 3 December 2009
fnxtr wrote:
"...how does the geneticist distinguish between similarities because of descent from similarities because of lateral gene transfer?"
You are correct, that can be a big problem. That is why it is so important to distinguish bewtween gene phylogenies and organismal phylogenies.
The short ansewer is that phylogenetic analysis can determine the relationships for different genes and even different parts of genes. There are certain patterns that are produced by descent with modification and other patterns that are characteristic of lateral gene transfer. These patterns can even detect mosiaciasm within individual genes. This general approach has been used to identify the origin of mitochondrial genes and mitochondrial derived nuclear genes and mitocchondrial derived pesudogenes.
Another approach is to look for tell tale signs of transfer events, such as those left behind by transposition, retrotransposition, processed pseudogenes, etc. As we discover more and more mechanisms of lateraal gene transfer, we are better able to detect the signs of these events.
I hope that that addresses your question. Others may feel free to add details or specific examples.

Brad,
When I was a child I was a Lutheran Protestant Christian and slowly drifted from the Church. I am now a satisfied Deist. However, I do have relatives who are Christians, Jews, Agnostics and Atheists, and at least two who are clerics; one is a retired Methodist minister and the other is a certain famous - or infamous (depending on your perspective ) - former United States Army Sunni Muslim chaplain. I've read the Bible several times, though I will admit that I haven't read it in years, nor do I really wish to when I have other, far more interesting, books that I am more interested in reading.
There are many religiously devout scientists who see no conflict whatsoever between their belief in an Almighty and recognizing that evolution is valid science. All I have known personally have put their scientific duties substantially way ahead of any religious feelings they may have, in stark contrast to the so-called "scientific" creationists at Answers in Genesis, Institute for Creation Research and other creationist organizations. None of the scientists who accept evolution as valid science regard it as a "belief"; a sentiment that I endorse wholeheartedly.

OK, here's one: Are viruses alive?
I guess a better question would be, Is there an accepted definition of life that lets biologists draw a line between life and non-life? I suppose this relates to creationism in that Genesis seems to make a clear and easily discernible distinction between those things given the "breath of life" and the nonliving. But I suspect that in reality it's not that simple.
Here's my tuppence worth: a wood frog hopping around is clearly alive. The same frog frozen solid is no longer alive. The fact that it is "resurrected" when it thaws doesn't negate the fact that while it's frozen, it's dead. The potential for life does not equal living.
Viruses, FWIW, I would say are in a twilight zone--sort of living--almost living. I guess that means that I don't see why there has to be an absolute boundary. Why can't there be a gray area? Sort of like ape-human ancestors. Creationists get bent out of shape drawing arbitrary lines between ape and human, but to us more reasonable folk--why does it matter? There should be many gradations that are ape/human. (Yes, I know, we are apes. And I, for one, am damn proud of the tremendous strides my ancestors have made.)
Dave Luckett · 3 December 2009
I believe that viruses pass one of the tests for "life" insofar as they reproduce, after a fashion. But the reproduction is termed "replication" due to the fact that they can only do it by using (abusing?) the chemical machinery within a living cell of some (cell-based) organism. Hence, viruses are not protolife. They are essentially parasites that have lost all functions that they can extract from a host, including even that of reproduction.
Is a frog alive if it is frozen solid and shows no sign of life? IMHO, if it can be thawed and when thawed, is plainly alive again, then it was always alive. It is only that the "signs of life" that must be looked for are more subtle than watching to see if it jumps about. But that's only one take on it.
One of the most horrible experiences anyone has when observing anything in nature - or in history, oddly enough - is when one realises that there isn't actually an absolute boundary between any two conditions. Or practically so.

I'm not sure I agree with that. Lenski's Avida program has actual evolution (including unique functions that are not 'programmed' into the system). Yet, I would not consider them life.
Other systems use genetic and evolutionary algorithms to generate novel features, but they are not alive nor produce living things.
Hmmm... it does bear thinking on.
Just Bob · 3 December 2009
And my admittedly demented brain continues to tick over (I suspect it's alive). About that frozen frog being alive--what if it never thaws? Is it still alive after 50 years? After 10,000? Suppose it's thawed after 100,000 years and it doesn't "come back to life." At what point during its big freeze did it "die"? How would you tell without allowing it to thaw?
And about cells: Don't slime molds have a stage without cell membranes, where they're one big blob with many nuclei floating around in them?

Ok so here is my question. Let me know what yall think.
My struggle with the Theory of Evolution is that it is limited to changes over time for the purpose of survival.
So here is where I’m at. I can see that there is evidence for some type of environmentally caused evolution. We can see it happening all the time (on a small scale) within animals and plants. It makes sense that birds beaks will change (depending on the environment) so that they can eat and survive. And over a long period of time the changes can seem very drastic. This falls in line perfectly with the ToE; environmentally induced changes through Natural Selection and random mutations. This happens so that animals and plants can survive. This is Darwin’s theory, which is about survival.
What doesn’t make sense to me is evolution in regards to humanity. Humans are very different from animals and plants. The intelligence found in humanity seems very unlikely to have evolved. I mean why would a being need to be able to read or write in order to survive? Why would he need to create music or paint a masterpiece in order to survive?
I also don’t see any examples of intelligence having evolved since the beginning of mankind. For example, in ancient Babylon there were air conditioners and other inventions to provide comfort. Mechanical machines are now used instead of the less elaborate systems 3,000 years ago. I will admit that humanity has tried many new things and technology is far more advanced than it was 3,000 years ago, but intelligence has not grown or evolved. Those who built the pyramids and the Roman coliseum were no less intelligent than those who built the empire state building or the personal computer. Each had different tools, materials, and purposes. The very fact that humans try new things and invent new things only gives evidence to the fact that they are unique.
In addition, the fossil record (to my knowledge) doesn’t have one clear piece of evidence for the progression from chimp to man. Sure we’ve found fossils over and over, claiming they are the “missing link” in evolution, but after more careful research they fall short of being human or chimp. Those fossils could have a number of reasons for their oddities and deformities. I understand that fossil research is hard because it is a great deal of speculation, and trial and error.
Still, it is hard for me to see how intelligence could have evolved so dramatically. Humans do more than just survive. They philosophize, create music, and make art. So if natural selection compounded by slow mutations over time is utilized for survival according to the environment, why would human intelligence evolve so drastically? Intelligence isn’t required for survival. Philosophy isn’t required for survival. Aesthetics aren’t required for survival. Animals and plants have survived without the same amount and depth of cognition of humans. So why are humans so different? And how can the ToE explain the drastic jump in intelligence if it goes outside the confines of the theory (i.e. it proposes something beyond survival)?
I think the intelligence of humanity is one of the biggest challenges to evolution. Study the fruit flies, the plants, the bacteria, all you want. Humanity is unique in comparison to them all.
Humanity is special. Somehow they are very different from the rest of the world. And it seems much more likely that humanity was designed or created differently from the rest. Biologically there are many similarities, but intellectually, humanity is far superior to everything else. And as I said before, humans have not evolved intellectually. We may have discovered more materials that we can manipulate, but we have not increased our mental potential.
So the ToE falls short in explaining the need for human intelligence. Is there a theory that does explain it? I can find only two options.
Intelligent design is not bound by the survival limits of the ToE. It even predicts it because a extremely intelligent designer could design and create something that had a similar intelligence and ability to design/create.
Creationism says that a Divine being created humans separately, and they were made in the image of God. This special creation can account for the drastic difference in the intelligence and creative ability of humans (that goes well beyond the confines of survival) in comparison with the plants and animals (not that the animals aren’t intelligent, they just aren’t on the same level as humanity).
Either of these, can explain the uniqueness of humanity. The ToE cannot.
Right?
John Kwok · 4 December 2009
Kevin (aka OgreMkV) · 4 December 2009
Not really.
First, I really suggest you watch all three episodes of the PBS Nova on Becoming Human (they are free on-line). That explains a great deal of the evolution of humans from our earliest ancestors to present and what evolutionary changes happened and when.
As far as the not evolving anymore... any proof of that, other than what you think should be happening? I'm not asking to be snotty, because at least one recent journal paper (2007 if I remember correctly) reports that human evolution is speeding up and has been for the last ten thousand years.
Finally, I suggest that you try to seperate (in your mind) the types of things that evolution does from the results of those evolutionary changes. For example, philosophy... evolution didn't develop a gene that allows us to be philosphers. Evolution developed our minds to be able to deal with concepts that are not immediately concrete (like, "if we don't leave here before winter, we'll starve") and advanced thinking and planning (like, "I'll chase the herd toward you and you jump out and stab the closest antelope with a spear"). These two traits taken together allow things like philosophy, advanced mathematics, etc.
Watch the Nova show, it's really very good. There's another one and the name escapes me about the work of the geneticist at the end of the Nova series. He went to a street fair in New York and took genetic samples of a hundred people or so, then used them to trace the changes in human DNA throughout our history. Really fascinating stuff.
BTW: Humanity is NOT unique. Yes, we think we're better than dolphins because we invented the internet, New York, and atomic bombs and the dolphins just eat, play, and have sex. Of course, the dolphins think they are better for exactly the same reasons.
Start doing some research on human genetics. For example, the proteins used in our eyes to absorb light are found in almost every organism on this planet (including most bacteria). Our genome is 99% the same as chimpanzees. We only think we're special and unique... and some people jsut can't accept that we really aren't.
So tell me, what are differences (measurement and expected values please) of a life form that is designed to be intelligent and one that developed intelligence from a naturalistic method?

Really? Well perhaps you should go to talkorigins.org and search the archive for the topic hominid evolution. There are at least twelve intermediates in the fossil record between humans and chimps. This demonstrates conslusively that chimps are the proper sister group to humans, a conclusion supported by all of the available genetic and developmental evidence.
Why exactly do you not accept the findings of scientists? Why exactly do you conclude that the intermediates all "fall short of being human oir chimp"? What do you think the characteristics of a true intermediate should be? Why do you think that anyone will care what you think if you cannot understand this simple concept?
raven · 4 December 2009
nmgirl · 4 December 2009
Mac, definitely watch the nova series. These are some of the ideas I took from the series:
as hominids became more removed from the apes, they became more and more defenseless: no big teeth, no claws, can't climb trees well, can't run fast, etc. I suppose physical adaptations were possible, but we took a different path. Our ape ancestors already had basic social skills and early hominids built on them. In order to survive they gathered into groups and over time these groups got larger. A larger group requires more social skills and different rules. Think of how much more complicated social interaction and communication becomes in your own circle as more people get involved.
And all this social activity was going on in conjunction with an unfriendly and variable physical environment. Our ape ancestors were well adapted to their environments so haven;t changed as much in the last few million years.
A human infant is a compromise between what a mother can safely carry and deliver and the survival needs of a hairless ape. I wonder if the physical weakness of that infant is a way to make the brain as big as possible at birth because there is so much learning that has to occur?

John, I have no doubt that Malthus influenced Darwin and Wallace, but he was and remains an economist first. His application was to resources (industry, raw materials, work), Darwin recognized that Malthus' thoughts could be more widely applied to non-human areas too. I agree that this is an important concept that helped Darwin.
I just don't think it will help Mac. Any decent history of Darwin (even most Ken Miller's high school Biology book) covers Malthus as much as he needs to be covered.
We've gone a long way since Darwin and Malthus and I think knowledge of genetics, current evolutionary thinking, and such as that would be more useful to Mac.

And a further thought on the glories of human intelligence:
Think of the many extinct animals whose extreme adaptations probably led to their extinction when the environment changed: Irish elk with giant antlers; mammoths with 4-meter tusks and hair all over; sauropods weighing as much as a herd of elephants, etc. It's the small, less extreme generalists that seem to come out the other side of major extinction events.
Now think of our "extreme" intelligence. Sure, it has had great adaptive benefits. But it could be as much of an evolutionary dead end as the armor of a glyptodont. Our intelligence has rendered us capable of destroying ourselves. No other creature has invented nuclear, biological, and chemical weapons. It's very possible, at least with nuclear and biological weapons, to destroy, intentionally or inadvertently, the entire human species. Also recall that at least for those of us in the "developed" world, we are almost completely dependent for our continued survival on the mechanisms of modern society. How long after an irreversible power grid failure would there be food riots, then mass starvation?
I maintain that the jury is still out on whether human intelligence will prove to be a successful long-term survival strategy.
If we fail, the "stupid" rats and cockroaches will continue just fine (unless, of course, we're "intelligent" enough to invent a way to destroy all multicellular life).
Oh, and BTW, we have invented religious factions that would gladly destroy the species or all life if they had the power.

After 8 pages of really stupid, icky bullshit, can we declare the idea that motivated this thread a failure?
I won't be back - this sort of thing can be found wherever heads are pointed, cheesy poofs are consumed, and hypocrisy and deceit are seen as the weapons of sexually-frustrated mens and wimmins.
I mean, yuck!

Great experiment Nick. Very revealing.

Yeah, you guys--cut it out!
The idea was good: straightforward questions and answers minus the contention, insults, and baiting (hey, it was MY idea).
Then a troll showed up with unrelated climate change crap, and you couldn't just let it go. (How's this--after each upCHUNK, simply state "We're ignoring you--do this elsewhere.)
Then you had to start in on each other. Nobody outside the 2 or 3 involved wants to read through that shite. Why don't you do that stuff in emails and spare the rest of us?

And while I'm unloading...some folks are way too quick to jump to insults (however deserved they may be by creationist trolls). The lurkers would get the point if the response were more like, "You're wrong and here's why," or, "You've been corrected on this many times before," or, "You don't seem to understand." Yes, be patronizing.
That resonates way more with watchers than calling them liars, sacks of shit, ad nauseum. They may be those things, but I'll bet they leave sooner or clean up their acts if they're calmly corrected on their childish misunderstandings by adult figures. Nobody likes being made out to look dumb and childish, but when schoolyard insults start to fly, who looks immature?

Kwok, I was one who debated your political views, and accepted that you had varied them in response to fact and evidence, as a good scientist should.
But I have always found that the only useful answer to intemperance and personal insults from others is an icy, impersonal correctness. (Although I will admit that my reaction to outright lies that I can clearly document is to call the liar a liar.)
May I be so bold as to recommend this course to you?

And what does the whole "assume room temperature thing" mean? It's pretty dopey. Can't you be creative? And use something understandable?

Well, this experiment was pretty much a failure. I didn't end up having the time to babysit. I'm closing it.
