Ancient Fossil Offers Clues To Primate Evolution
langelgjm sends in an update to a story we discussed over the weekend about an extremely well-preserved fossil of an ancient primate, Darwinius masillae, that sheds light on an important area of evolution. The 47 million-year-old specimen has now been officially unveiled, and while many media outlets are stumbling over themselves with phrases like "missing link" and "holy grail," it's clearly a very impressive find. "Discovered two years ago, the exquisitely preserved specimen is not a direct ancestor of monkeys and humans, but hints at what such an ancestor might have looked like. According to researchers, 'The specimen has an unusual history: it was privately collected and sold in two parts, with only the lesser part previously known. The second part, which has just come to light, shows the skeleton to be the most complete primate known in the fossil record.' The scientific article describing the find was published yesterday in the peer-reviewed, open-access journal PLoS ONE. Google's home page is also celebrating the find with a unique image." Science blogger Brian Switek offers some criticism of the academic paper and the media swarm, saying, "I would have hoped that this fossil would receive the care and attention it deserves, but for now it looks like a cash cow for the History Channel. Indeed, this association may not have only presented overblown claims to the public, but hindered good science, as well."
... says it's a hoax. Any takers?
Actually, even if not, the circumstances are now rather dubious. Hopefully it hasn't been damaged in the course of it being sold in two parts and shipped around in private hands.
Interesting New Scientist blog: http://www.newscientist.com/blogs/shortsharpscience/2009/05/is-ida-a-pop-star-fossil-or-po.html They seem to make two main points- firstly that the whole thing is degenerating into hype, but more interestingly that there wasn't a big debate here anyway. Yes, it's a missing link, but it's one that all rational people knew must have existed somewhere. It hasn't ignited debate between creationists and evolutionists, for the reason that they don't really debate each other anymore- at least not in scientific circles.
Honestly, the only reason anyone ought to care what a politician thinks about creationism is if they decide what's taught in public schools. This is almost always a state matter. Your U.S. Congressman has bunk to do with it.
Ah, yes, thanks for reminding us about the theory of federalism, on which our governing system is ostensibly based.
Now I'm going to explain to you how it works in the real world.
In the real world, the national government has become intimately involved in decisions at the state and local level, well beyond its enumerated powers. If nothing else, federal funding of local education has enabled it to threaten states with, "Don't want to do what we tell you? Then kiss your funding goodbye."
Yes, the federal government does have significant control over what can be taught in public schools. Why do you think the Supreme Court ever rules on cirriculum issues? Why don't federal judges respond to all such lawsuits that make it to their level by saying, "Meh, state matter, go away"?
So please don't act like Congressmen are powerless over what's taught in public schools.
Information theory is life. The rest is just the KL divergence.
