The exact times to your questions are unknown. If someone claims they know they are lying. This is because fish did not suddenly become a distinct reptile, they gradually started to evolve reptile characteristics.

However it is assumed and generally accepted that mammals evolved from reptiles and not birds. Humans did not directly appear from reptiles, they decended from mammals. Humans have only been around for 130,000-190,000 years and the mammal ancestor split from reptiles about 359.2 ± 2.5 million years ago.

They didn't. Fish are fish and reptiles are reptiles.

Yes it is a popular modern myth but no proof has ever been produced for any of the transitional forms..... of which there should be tons and tons.

I am speaking from a scientific viewpoint only. If there is no proof and no evidence to test then all thats left is conjecture and hearsay.

My money's on freshwater fish being the ancestors of amphibians. want to understand some thing humorous? My money's on freshwater fish being the ancestor of in the present day's marine bony fishes. The bony fish of in the present day are so hypotonic with appreciate to the marine surroundings that that's merely undeniable extraordinary otherwise. (certain, that is an argument from own incredulity).
