Turtle singing before audience, made with DeepAI Using universal common descent evolutionary presuppositions, there was something I found surprising: It was concluded that acousting communication did not evolve multiple times in the groups they studied. Instead of convergent evolution, researchers pushed the problem back into the mists of imagined time. There was one ancestor, but nobody knows what it was. They have no evidence (fossil or otherwise) for evolution in the first place,...
