The atheists & homosexuals have recently (within the last 15 to 20 years) taught some chimpanzees & bonobos (small chimpanzees) to engage in homosexual acts. They filmed these things in wild-life preserves that were meant to look like their natural habitat. This was all so homosexuals could say that apes were doing these things. Some atheists & homosexuals know of this film and will direct your attention to it as proof that homosexuality is 'natural.' Just beware. A lot of wild-life documentaries involve staged scenarios, otherwise it would have been impossible to get some of the shots. A famous incident is where some rodent was said to commit mass suicide 'naturally,' by jumping off the side of a mountain. The truth was the 'mountain' was a televised studio table meant to look like their natural habitat, and the rodents were simply trying to get off the table, not commit suicide. It took many years to expose this fraud. Some biologists thought it was real (it was meant to appear real), and wrote books about it.

Final word: apes are not naturally homosexual, but some atheists, and/or homosexuals will tell you of the film of the chimps.
