Wang, cataloging 853 skeletal characteristics in 150 dinosaurs and analyzing the rate at which these characters change, and they found that "there was no grand jump between nonbirds and birds in morphospace."

Creationism stays out of Texas textbooks (for now)

On Friday, July 22, the Texas Board of Education voted 14-0 to support scientifically accurate high school biology textbook supplements, rejecting the proposed creationist materials.
