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.
