:You're right; there is NOT greater similarity between humans and gorillas than humans and chimps, and the article isn't intended to say that; the point is that there are SOME SEQUENCES that are more similar, which contradicts the evolutionary hypothesis that we have a mmore recent LCA with chimps than with gorillas. The confusion is my fault and I'll fix it. --[[User:SamCoulter|SamCoulter]] 16:05, 22 September 2011 (EDT)

::It still doesn't contradict evolution at all. Say we start with 4 genes, A, B, C, D. The gorilla branches off earliest and takes with it A, B but has evolved two new ones, W, X. The chimpanzee branches off from the original line later on, but takes with it A, C, D and evolves Y. Humans on the other hand branch off last taking B, C, D and evolving a new one, Z. Now, humans share only one gene with gorillas but two with chimpanzees. However, it so happens that the one they share with gorillas is not also shared with chimpanzees.
Obviously this is a ridiculously simplistic analogy, but it demonstrates that it is perfectly possible for one species to be more closely related to humans, with a more distantly related species still sharing DNA sequences only with humans. Even if you don't accept the concept of evolution, there is no contradiction with its internal logic. [[User:DavidZa|DavidZa]] 16:53, 22 September 2011 (EDT)
