Convergent evolution creates analogous structures that have similar form or function, but that were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy, from Greek for same form. The recurrent evolution of flight is a classic example of convergent evolution.unctionally similar features arising through convergent evolution are termed analogous, in contrast to homologous structures or traits, which have a common origin, but not necessarily similar function.
1.2 Ma. Homo antecessor may be a common ancestor of humans and Neanderthals. At present estimate, humans have approximately 20,000â25,000 genes and share 99% of their DNA with the now extinct Neanderthal and 95-99% of their DNA with their closest living evolutionary relative, the chimpanzees.omo heidelbergensis may be a common ancestor of humans and Neanderthals. It is morphologically very similar to Homo erectus but Homo heidelbergensis had a larger brain-case, about 93% the size of that of Homo sapiens. The holotype of the species was tall, 1.8 m (6 ft) and more muscular than modern humans.
