Shoshani found 29 morphological synamorphies for this grouping. Bauer and Shreiber deal with this apparent contradiction, by suggesting that the radiation of the Homo, Pan, and Gorilla trichotomy took place in a relatively short time. It is currently believed that their common ancestor was chimp like. Shoshani's tree may be seen in the Primate page . This is the tree that Bauer and Shrieber suggest based on their results.
Approximate time is shown on the left.
This tree of just the Hominoids was proposed by Ruvolo. It shows approximate age of the LCA of the species based on mitochondria DNA studies.
