Palaeontologists were concerned because few consider the extinct group to which Darwinius belongs, the adapoids, to be close to the anthropoids. Erik Seiffert and colleagues now describe the jaw and teeth of Afradapis, a newly discovered 37-million-year-old adapoid from Egypt. This was a close relative of Darwinius. Although detailed phylogenetic analysis shows that the new form — like Darwinius — was only distantly related to anthropoids, it does have a few features that suggest convergent evolution. It is likely that Darwinius and Afradapis are members of a group that convergently evolved some anthropoid-like adaptations in the middle Eocene, but that were eventually replaced by true anthropoids in the late Eocene and early Oligocene.
