So it is true, there has been some monkey business between the predecessors of humans and chimpanzees.

It appears that new DNA test results prove that the split between humans and chimpanzees happened differently than originally thought and that the difference from previous results are because tests nowadays are much more sensitive. It also suggests that there was some daliances with interspecies mating after the split occurred.

Interesting. Did interspecies fetishism and bestiality exist at that time too?
