Re: So, why don't we still have dinosaurs?
"Alternatively (more or less like the much later merger of proto-eukaryote cells with prokaryote, in which case the latter turned into organelles such as mitochondriae and chloroplasts within eukaryote cells), the new forms might have been assimilated within the older ones."
There's a shared biochemistry in terms of genetic coding between the eukarytotic and prokaryotic components to suggest a common origin followed by a period of parallel evolution before one assimilated the other.
