Hmmn ... nice fossil but not really what I was thinking about. We were talking about "Four-legged large animals", i.e. how did Tyrannosaurus Rex that lived about 65 million years ago (which is really 2 arms and 2 legs and a tail) become a kangaroo ( 2 arms and 2 legs and a tail) or the Brontosaurus (4 legs and a tail) that lived about 140 million years ago become a cow (4 legs and a tail), for example?surya2037 wrote:The four-legged land animals as Baba already mentioned
You might also ask what brought them about in the first place?
Really, we fall back on the mystical, unexplained "magic wand effect" that transforms humans into deities and dinosaurs into lambs.
Who waves this magic wand and how does it work?
If there are no answers then I am afraid that we are just in fairy story land because such things only happen in children's fairy stories.
