Secular biologists, who claim that the common ancestor of today’s two sloth genera lived 35–40 million years ago, admit the evolutionary history of the two living sloth groups is not well known. Interestingly, though, they believe that despite the extensive similarities between the two genera, each is much more closely related to some of the extinct ground-dwelling sloths than to the other living sloth genus. They are forced to consider living sloths as stunning examples of ‘parallel evolution’—repeat evolution of similar traits, by sheer chance, in multiple lineages.
