Having bought a bunch of bargin bin books at Borders on the study of dinosaurs, most seem to state that birds are descended(sp?) from dinosaurs or even ARE a form of dinosaur.
The evidence they site as why some people say it isn’t so is weak compared to why they are.
After looking on the internet the only arguments I can find against birds being descendents of dinosaurs are very technical.
So what is the SD? Does anyone have a layman’s version of why birds are not descended from dinosaurs.
