Yes new scientific imagination has concluded that somehow a small little deer like creature.
So here is the problem, first they claim we all come from fishes that evolved somehow into things with legs. Now they claim the thing that evolved from the fishes got scared after he grew legs and somehow managed to jump back into the water and ungrow his legs? That just doesnt make sense. According to the theory of evolution and one of the theories of Charles Darwin, the strongest survive. So the relevant theory to evolutionists should be those little creatures died out. But no, somehow that managed to skip the theory of evolution and put it in reverse because they got scared. Yes. That is modern day science for you.
