It's been a while since I
wrote about Primordial Soup - and it's Back in the News!
Science Daily reports on March 21st that
Stanley Miller gained fame with his 1953 experiment showing the synthesis of organic compounds thought to be important in setting the origin of life in motion. Five years later, he produced samples from a similar experiment, shelved them and, as far as friends and colleagues know, never returned to them in his lifetime.
More 50 years later, Jeffrey Bada, Miller's former student and a current Scripps Institution of Oceanography, UC San Diego professor of marine chemistry, discovered the samples in Miller's laboratory material and made a discovery that represents a potential breakthrough in the search for the processes that created Earth's first life forms.
Former Scripps undergraduate student Eric Parker, Bada and colleagues report on their reanalysis of the samples in the March 21 issue of Proceedings of the National Academy of Sciences. Miller's 1958 experiment in which the gas hydrogen sulfide was added to a mix of gases believed to be present in the atmosphere of early Earth resulted in the synthesis of sulfur amino acids as well as other amino acids. The analysis by Bada's lab using techniques not available to Miller suggests that a diversity of organic compounds existed on early planet Earth to an extent scientists had not previously realized.
"Much to our surprise the yield of amino acids is a lot richer than any experiment (Miller) had ever conducted," said Bada.

I just want to remind all ID/creationists that developing models of abiogenesis are another nail in coffin of their ideas.
It doesn't work the other way around. If a deity manifests itself tomorrow and shows everyone how the first cellular replicator was magically created, the theory of evolution is still strong (and ID/creationism is still wrong).

Wöhler synthesized the first organic compound in 1828 if I remember the date correctly. Whether or not they can recall these details, I assume that almost every regular on Panda's Thumb has known for a very long time that there is nothing magical about producing organic chemicals in the lab. Thing is, though, it's news to plenty of people, including, perhaps, Intelligent Designer. A critical important fact doesn't turn into an innate idea no matter how obvious it appears if you learned it long, long ago. One normally thinks of the difference between theologically oriented and scientifically oriented people as a function of their world views, but it's my guess that at least a good chunk of the mutual incomprehension comes from simple ignorance. There really are people who don't know what causes the tides, let alone the good news about amino acids.

In fact I wrote this cool little program that show what happens to coding sequences when they are modified. It might be an eye opener for some. I call it Genomicron. This was the blog entry I wanted some peer review from.
What would be cooler to shows though is what happens to the shape of protiens when their coding sequence is modified. I need to learn a little more chemistry before I can write a program to do that. I am working on it on it though.

Incidentally, the phenomenon you describe can be expressed as the difference between "dialectic" and "debate".
You don't hear the term "dialectic" much any more. It's an old-fashioned term for the use of well-constructed arguments in an effort to convince a reasonable skeptic. It's essentially one of those academic areas which has been subsumed into the sciences.
US culture, meanwhile, has massively adopted the term "debate". All disputes are referred to as "debates" in the media. Science supporters, interpreting the word "debate" to imply honest dialectical dialog (possibly due to the usage "parliamentary debate", but parliamentary proceedings are actually, at least ideally, a form of dialectic), often say "there is no debate". In fact, science supporters are wrong about "debate". Debate exists whenever someone disputes a point, however wrong they may be in doing so. (The media is even more grossly wrong, constantly implying that the "true" answer is somewhere "between the two sides of the debate", when it is always plausible, and probably more likely, that one side or the other is simply correct.)
But technically, debate means competitively trying to advance a position regardless of objective evidence. The sport of "formal debate" proceeds exactly this way. In fact, it is considered a major error to ever concede a key opposing point in a formal debate, no matter how reasonable that point may be outside the narrow context of the debate. Formal debate actually has an authoritarian flavor. Each side is limited to a fixed amount of time, even if one side is supporting a position which is far more strongly supported by evidence. In depth analysis of propositions is not a goal. And an authority figure or panel of authority figures arbitrarily declares one side the "winner".
It is no coincidence that right wing fundamentalist universities place heavy emphasis on competitive debate.
Minds which are rendered excessively concrete and authoritarian, either due to innate problems in cognition or personality structure, active application of brainwash, or physical trauma to the brain (broadly defined to include illness), generally gravitate instinctively to "debate", rather than dialectic.

I'm going to say the same thing to you that I said to Dale.
There is a difference between "intelligent design", which nobody cares about, and "Intelligent Design" (ID), associated with the Discovery Institute, and with authors such as Dembski, Behe, Johnson, Wells, Luskin, etc. The former is just a common human activity; once again, I'm intelligently designing a comment.
The latter is a specific type of evolution denial. The works exist specifically to deny evolution, and DI fellows often refer to "evolutionists" when referring to their adversaries.
For example - Behe claimed in at least one work that biological structures or pathways with "irreducible complexity" could not have evolved. He offered the bacterial flagellum as an example of something that could not have arisen through evolution. At the Dover trial, ID-supporting "expert witnesses" (the ones who actually testified) all or virtually all showed up with material about the bacterial flagellum.
It is critical for supporters of science education to distinguish between "intelligent design" and "Intelligent Design".
One of the strategies of the DI is precisely to use an innocuous sounding term to mislead the casual observer about the nature of its science denial.
The scenario I described (deity magically created first cell and evolution proceeded from there) might support "intelligent design", which is irrelevant, but any scenario which contains biological evolution does not support ID.
To remind everyone, I don't advocate the idea that life began by magic, I was just pointing out that ID/creationism is worthless whether or not a good model of abiogenesis is available.

Well, of course, you refuse to answer any substantive questions (yes, we all know you don't "have to", but a reasonable person would), but anyway, here's another question that occurs to me.
Since you're a great genius and your chosen field is mathematics, why are you trying to overturn the main theory in biomedical science, instead of using your superior intellect to advance the field of mathematics? The great unsolved problems of mathematics should be easy for one of your talents.

IMO, "theistic evolution" is a term that needs to go away.
There are a number of theists (like me) who (like me) accept that modern evolutionary theory is the best available scientific explanation we've got for the diversity of terrestrial life. Period. The evidence is clear, convincing, and abundant. (The fact that it's a beautiful explanation is an added bonus for me.) These people (like me) get called "theistic evolutionists". This would be, I suppose, an acceptable way to describe people like me, except for a couple of problems.
The first problem is, the term suggests that theistic evolutionists advocate something called "theistic evolution". This is often incorrect; in my case, the "theistic" applies to me and not to evolutionary theory. This leads to the second problem: some people are wont to believe that, as a "theistic evolutionist," I think that God intervenes, perhaps undetectably, the evolutionary process here and there to get a desired outcome. I don't think that that's the case; no divine tweaking is needed.

Your problem is partly that when you lie down with dogs, you get up with fleas. The rest of your problem is that ID is wrong. You're wrong.
It really doesn't matter a hoot who your fellow-travellers are. They make you look even wronger than you are, of course, but let's face it, when you're wrong, what you look like doesn't really matter. You're still wrong.
As for what harold believes about the existence of God and what God does or doesn't do, it's nothing to do with you or ID. Your enquiry is, in the classic sense, impertinent. You and it are still both wrong.

BUT one of the two major parties has a few members who represent my views to a decent degree, and Independent Senator Bernie Sanders, who represents my views with a high degree of overlap (no, I am not from Vermont), usually votes with that party.
At least there is a party that tolerates some members and allies who come close to representing my views. It isn't much, of course.
The other major party seems to have been entirely taken over by either theocrats, or people who are willing to compromise with theocrats.

One final comment.
Paradoxically, we may not be as far apart as it would seem. Before George W. Bush was elected I had relatively few problems with honest conservatives.
I'm in favor of a capitalist system as opposed to a command economy, I'm against government waste (to the best of my knowledge everyone is), and if you're not a theocrat, it's plausible that my strong support for full legal rights for my gay fellow citizens (and for all my other fellow citizens) and my support for things like legalizing marijuana, wouldn't bother you.
I do strongly support social programs for the needy and universal access to health care, but I will remind you that the former make up a fairly small proportion of overall government spending, and that we already provide Medicare to all of the oldest and sickest members of the population. I also support strong public education from kindergarten to the doctoral level, and honest regulations to prevent destruction of the common environment. However, that last one is just free market capitalistic common sense. We all breathe the same air. Either people should be restrained from polluting it for their own selfish purposes, or they should have to bear all the costs associated with their own actions.
I used to think that libertarians were closer to me than they were to authoritarian theocrats.
I lost my patience with libertarians when they explicitly or implicitly supported destruction of human rights and wars of aggression under George W. Bush. And yes, I agree, now that Bush/Cheney established the precedent, the following administration has not moved strongly to reverse it - all the more reason not to establish it in the first place. Of course we are now stuck with a more "imperial" presidency than we used to have, and the blame is shared, but not equally shared - the guy who started it is more to blame.
If libertarians are against both imprisonment without trial, and food stamps, and I'm only against the first one, that's one thing. But if libertarians prioritize being against food stamps and wind hypocritical justifications for imprisonment without trial, for example, well that's very different.
I'd love to get back to being able to dialog and work with reasonable conservatives, but the events of the last ten years have made me much more cynical.
This will be my final comment on this topic.

IDer,
No prob. Things can get pretty nasty on here and I dont think its necessary. I dont think most IDers are dishonest but I understand why it appears that way to the science advocates. Its had to do with the initial assumptions: Scientists make only the assumption that the world is understandable, but ID advocates start with the premise that the universe was made by God. They look for individual scientific facts to disprove that which will never happen of course. It seems to me that when one looks at the totality of scientific evidence objectively there is no evidence for intelligent intervention in the natural world and overwhelming evidence for evolution

I prefer to avoid the whole question of whether or not Creationists know they're saying things that aren't true; I just call them false witnesses, and point out that they're bearing false witness. Since the Bible does tell us that "thou shalt not bear false witness" is one of God's Commandments, I think it makes a good deal of sense to use that phrase when calling a Creationist out on their many, many falsehoods. Sure, calling a Creationist a 'false witness' isn't likely to get that Creationist to abandon his lies... but it may have a salutary effect on people who read the posts at whichever later date.

Here is a link to a science fiction story with intelligent design and panspermia elements. I took a course in physical anthropology from the author. http://en.wikipedia.org/wiki/Transfusion_(short_story)
Panspermia is an old idea, but it just pushes the question of origin of living things to out there somewhere. Because the only place we are sure there is life is planet earth, the most parsimonious (but not necessarily correct) assumption is that life originated here.
We do not know how life originated. if it was a supernatural event, it is outside the scope of science. If we assume, however, that it was a natural event, we can then study the matter. Even if our assumption is incorrect, we will learn a lot of interesting things from our effort.

Dave Luckett · 28 March 2011
The reason why a geneology was given for Jesus is that the prophecy required that the Messiah be of David's line, "a root of Jesse" (Isaiah 11:1)
Of course the rest of the prophecy given in that passage was conveniently ignored. Take a look at what it says the Messiah will do, and reflect that Jesus, whatever other things he was, could not be that Messiah. And if he wasn't, then someone in the Bible got it wrong.
That's also why Jesus has to be born in Bethlehem, even though everyone knew he was from Galilee. A story had to be told. Several stories, in fact, all of them whoppers.
Oh, and the attempt to explain the inconsistency of the genealogies in Matthew and Luke by making one of them Mary's and the other Joseph's? Another whopper. This is what comes of assuming your conclusion, then and now.

Hmm... either God has His own DNA, which was somehow combined with Mary's (in other words, SEXUAL reproduction), or He created some on the spot, specially for Jesus (bioengineering).
Or else Jesus didn't really have human DNA at all. Maybe that's why, according to the Bible, he never demonstrated any sexual interest in women (unless we do some reading between the lines about Mary Magdalene). But if he didn't really have natural human DNA, then he WASN'T HUMAN! Seems like that would make him an android or golem or something.
So how about it? Did Jesus have a full complement of naturally derived DNA from a pair of parents with human DNA or not?
