A team of researchers, including University of Edinburgh paleontologist Stephen Brusatte and Swarthmore College Associate Professor of Statistics Steve C. 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." In other words, birds didn't suddenly come into existence, but evolved, bit by bit, or characteristic by characteristic. But when birds were finally a thing, they went crazy. "Once it came together fully, it unlocked great evolutionary potential that allowed birds to evolve at a super-charged rate."
