Clos is a Creationist?
But we wouldn't expect you to have any idea of the actual science because creationists sources misrepresent the actual science out of necessity. Your doing it when you suggest that those features are what cladograms are based upon, even if your using a legitimate source, you are misrepresenting the context that “The formation of the group is based upon shared evolutionary traits and descent is shown by the grouping?”
No, that is absolutely incorrect. Formation of the group is based upon a shared evolutionary trait and CONFIRMED by DNA analysis.
