The most charitable interpretation is âwell crocodiles didnât change in the last 100 million years but birds did so that means maybe crocs are closer since birds evolved to get farther awayâ
Thatâs dumb because both birds and crocodiles have been changing the whole time. Just because crocs look more similar to their fossils, doesnât mean they havenât been evolving/drifting/etc.
Same thing any time someone talks about âsharks havenât changedâ. Itâs dumb.
It has nothing to do with if the said animal were evolving or not. Birds and Crocodilians are the only living animals of the Archosauria clade. Since birds are dinosaurs, technically they aren't their relatives. So Crocs are the closest living relatives of dinosaurs (and birds), since they belong in the same clade and shared a common ancestor more recent than anyone else alive.
