You Want Transitional Fossils?

Carl Zimmer has the story.

A graduate student at the University of Chicago named Matt Friedman was starting to research his dissertation on the diversity of teleosts. While paging through a book on fish fossils, he noticed a 50-million year old specimen called Amphistium. Like many fish fossils, this one only showed the bones from one side of the animal. It was generally agreed that Amphistium belonged to some ordinary group of teleosts, although biologists argued over which one. But Friedman saw something different. To him it looked like a flounder.

Sesquicentennial

It’s been a hundred and fifty years since Darwin first presented his thesis. Charles Johnson has some thoughts. I may have some as well, later. Or not.

[A minute or so later]

Well, actually, I do now, in light of Lileks’ comments this morning, in which he pointed out the simplistic, stilted views of many across the political spectrum. I’ll repeat:

Really, if one wants to cling, bitterly, to the notion that a believe [sic] in lower taxes and strong foreign policy and greater individual freedom re: speech and property automatically translates to a crimpled, reductive, censorious view of pop culture, go right ahead.

Similarly, if one wants to cling, bitterly, to the notion that a concern about Islamism, and an inability to realize what an evil stupid fascist criminal George Bush is translates to a belief that the world was created by Jehovah six thousand some years ago, complete with dinosaur bones, go right ahead.

Before 911, Charles Johnson was a Democrat, and a jazz musician. Almost seven years ago, he got mugged by reality. That, combined with some scary things that were happening at a mosque near his home in Culver City resulted in a change in emphasis at his web site. Now many of the left wingnuts who read LGF stupidly assume that he’s a “right” wingnut. Yet here he is, defending science from places like the Discovery Institute, on a semi-daily basis.

I get the same idiotic treatment, much of the time. I’ve often had discussions on Usenet whereupon, when I argue that maybe it wasn’t necessarily a bad idea to remove Saddam Hussein’s boot from the neck of the Iraqi people, and that I don’t believe that George Bush personally planted the charges in the Twin Towers, I am told to go back to whatever holler I came from and play with my snakes, and am informed that my belief in a Christian God, and my lack of belief in evolution is just more evidence of my irredeemable stupidity, despite the fact neither religion or science had been on the discussion table.

I then take pleasure in informing them that I am an agnostic and for practical purposes an atheist, and that I am a firm believer in evolutionary theory, it being the best one available to explain the existing body of evidence. Whereupon, I am sometimes called a liar. Really. It’s projection, I think.

Same thing often happens here, in fact. I tell people that I’m not a Republican, and have never been, nor am I a conservative, and I’m accused of lying about my true beliefs and political affiliation.

C’est la vie. There’s no reasoning with some folks.

In any event, happy birthday to a controversial but powerful (as Dennett says, absolutely corrosive, cutting through centuries of ignorance) scientific theory. Expect me to continue to defend it here, and Charles to defend it there.

[Late evening update]

Well, Iowahawk has the comment du jour:

I’m a dope-smoking atheist writer for a San Francisco lowbrow culture mag; I also enjoy seeing 7th century genocidal terrorist shitbags getting waterboarded. I really don’t see the contradiction.

Better Diagnostics

…through metabolites:

Douglas Kell, a researcher at the University of Manchester in Britain, has already created a computer model based on metabolite profiles in blood plasma that can single out pregnant women who are developing pre-eclampsia, or dangerously high blood pressure. Research published last year by Rima Kaddurah-Daouk, a psychiatrist at the Duke University Medical Centre in America, may not only provide a test for schizophrenia, but also help with its treatment. She found a pattern of metabolites present only in the blood of people who had been diagnosed with schizophrenia. The patterns change according to the antipsychotic drugs patients take and this may throw light on why some respond well to certain drugs, but others suffer severe side-effects.

This seems very promising, and near term. This part is a little misleading, though:

Studying genes alone does not provide such detail. Genes are similar to the plans for a house; they show what it looks like, but not what people are getting up to inside.

This implies that the genome is a blueprint–that the body is built by following a plan. But that’s a bad analogy. A much better one is a recipe. First do this, then do that. If it were a blueprint, identical twins would be truly identical, and indistinguishable. But because it’s a recipe, there are subtle differences (e.g., fingerprints) because the genome doesn’t specify the body design to that high a level of detail, and much can depend on womb environment (one reason to think that this could be a strong factor in the creation of homosexuals, in addition to genetic predisposition).
