Quote from: Shane for Wax on February 04, 2012, 08:57:07 pmchimpanzees, elephants, manatees, whales, and horses all apparently have them. But I couldn't begin to tell you about them. Maybe the chimps if I set my mind to it and studied it. If there's someone who is more knowledgeable about the above animals then maybe they can help and I welcome their knowledge. Anything outside of primates is beyond me for the most part (unless it's wolves and snakes).Elephants and manatees are so distantly related to all the other mammals above that it's likely a primitive condition for most placental mammals.Which means it's been around anywhere from the Late Jurassic to the Early Paleocene depending on phylogeny, so it's unlikely to be vestigial.
