Koko is a domesticated lowland gorilla who has been taught to use human sign language. Beginning when Koko was one year old, psychologist Francine Patterson taught the gorilla signs from American sign language; Patterson eventually credited Koko with learning a vocabulary of over 1000 signs.

Perhaps this is evidence that man had sex with monkey after all, long ago.
Ah! That mustache!
Koko more than signing ... when a trainer pointed to a sink that had been pulled from the wall in Koko's enclosure, Koko immediately signed: "Kitten did it. "
@Anonymous and perhaps that's evidence that you don't know the difference between an ape and a monkey.
