PZ Myers has presented another one of his usual breath taking articles, this time on the bird/alligator link...

<quote>y daughter is learning about evolution in high school right now, and the problem isn't with the instructor, who is fine, but her peers, who complain that they don't see the connections. She mentioned specifically yesterday that the teacher had shown a cladogram of the relationships between crocodilians, birds, and mammals, and that a number of students insisted that there was no similarity between a bird and an alligator. I may have to send this news article to school with her: investigators have found that a mutation in chickens causes them to develop teeth—and the teeth resemble those of the common ancestor of alligators and chickens, an archosaur.</quote>
