Obviously, the topic should be in the Science forum but seeing as it will degrade into creationists and realists bashing each other, I thought I would post it here instead. In that respect I suppose I am really just being a troll 😛!

An analysis of the laughter, presented in the latest Current Biology, revealed that human laughter is most similar to that of chimpanzees and bonobos. Next in line, in terms of similarity, are gorillas, followed by orangutans and siamangs, which are lesser apes.
"These results coincide with the genetic topology of great apes and humans," Davila Ross said.
Obviously the fact that the degree of similarity in laughter between species closely matches the genetic relationships between them (and thereby, the current models of human evolution) in no way proves that we and they evolved from a common ancester. However, it is another set of data that lends further weight to the already mountainous amount of evidence for it.
