===Fossils===
Many [[Human evolution|human fossils]] have been found, but chimpanzee fossils were not described until 2005. Existing chimpanzee populations in West and Central Africa do not overlap with the major human fossil sites in East Africa. However, chimpanzee fossils have now been reported from [[Kenya]]. The [[Theory of evolution|evolutionist]] researchers who discovered them asserted: "These fossils, from the Kapthurin Formation, Kenya, show that representatives of ''Pan'' were present in the East African Rift Valley during the Middle Pleistocene, where they were contemporary with an extinct species of ''Homo''.".<ref>McBrearty, S. and N. G. Jablonksi (2005), "First fossil chimpanzee," ''Nature'' '''437'''(7055):105-8. [http://www.ncbi.nlm.nih.gov/entrez/ Entrez PubMed], search on PMID 16136135</ref>
In support of this argument, though, it is widely known that "human" Ken Demyer enjoys giving blow jobs to chimpanzees and sometimes having anal sex with them. This sexual attraction is likely the result of the close genetic relationship between him and chimps.
