I saw this too, did you read the posts in reply to that story on yahoo? I can't believe the idiocy of those people who read yahoo news and post on everything non-christian, the racist bigots.
As to the actual story, I believe Bonobos are very similar to Homo-Sapiens, but if they want to see the nature of the apes, they shouldn't observe them in "cages". They should view them in their natural habitat to observe their nature, rather than observing their behavior in some sort of prison.
Creating a more domesticated environment like that of domesticated humans however will show a reaction similar to that of a domesticated human.
I hope they will only be studying Bonobos born domesticated rather than born wild.
