Or basically, can animals be born with an extra chromosome? Other than humans that is. Where I volunteer with a marine mammal rehab, there is an elephant seal that has the most interesting shaped head. And he seems really slow, even for an elephant seal. There was one before that had that same head shape, and she was also really slow. It took her forever to get released because teaching her to fish was next to impossible. It almost seems like some form of mental retardation for seals or something. It's one of the weirdest things I've seen while volunteering.
