An analysis of ancient fish fossils suggests that mammalian and fish tails are fundamentally different structures, each with unique evolutionary histories.
Chris Mooney's "The Republican War on Science" showed up on my desk recently. The book traces the rise of the Republican Party's split with science, from its roots in the supersonic transport debate in the Nixon administration, to George W. Bush's assault on science today, covering science issues from Reagan's "Star Wars" initiative to "intelligent design," global warming to stem cells. From what I read Mooney seems to come across as a bit of a zealot.
