Apparently suspicions that multiple hominid species coexisted have been confirmed. Two fossils found in Kenya have been revealed to be of Homo habilis and Homo erectus. The two fossils date to 1.44M years-old and 1.55M years old, respectively. Previously, the predominant theory had habilis as the origin of erectus but this latest report, published today in Nature and reported in the New York Times, would mean the two evolved from a common ancestor, with habilis eventually becoming extinct and erectus surviving.
The erectus skull, which is one of the least-evolved examples of the species discovered to date, is also significant in that it shows the erectus species was not as evolutionarily close to modern-day sapiens as expected. However, scientists speculate it would still realize Dane Cook is not funny.
