This is probably why the Dinosaurs were wiped out:
“the sons of men in those days took from the cattle of the earth, the beasts of the field and the fowls of the air, and taught the mixture of animals of one species with the other, in order therewith to provoke the Lord; and God saw the whole earth and it was corrupt, for all flesh had corrupted its ways upon earth, all men and all animals.” - Jasher 4:18

All we really know about it is found in the two Scripture quotations mentioned earlier. The other books by that title are mere fictions or Jewish moral treatises.
Interesting idea.
Most people have been taught, and think, that animals were all wild, but that mankind domesticated a few of them. I think it was the other way around - all animals were domesticated, originally, but the fall into sin made/allowed them to become wild.
However, from what we are finding out about the world, the people before the time of the Great Flood of Noah's day were super scientific in all they had and did. They were simply focused on science that was different than ours. They may have known aspects of genetics that are way beyond us so far.
