The split between the human line of ancestry and the line of the chimpanzee and the bonobo is believed to have occurred a mere eight million years ago. The subsequent divergence of the chimpanzee and the bonobo lines came much later, perhaps prompted by the chimpanzee's need to adapt to relatively open, dry habitats.
In contrast, bonobos probably never left the protection of the trees. As such bonobo may have undergone less transformation than either humans or chimpanzees. It could most closely resemble the common ancestor of all three modern species. It is suggested that the animal might be most similar to the primogenitor, since its anatomy is less specialized than is the chimpanzee's. Bonobo body proportions have been compared with those of the australopithecines, a form of prehuman. When the apes stand or walk upright, they look as if they stepped straight out of an artist's impression of early hominids.
Those who met Kermit were always in awe of his size, intimidated by his displays, and captivated when they saw his soft side. He was often seen with his thumb in his mouth while watching television. He was a vulnerable, sensitive chimpanzee who just wanted everyone in his family to get along. On February 27, 2006, Kermit and the rest of his chimpanzee family were loaded onto a truck and shipped from OSU to Primarily Primates where they were ill equipped to care for animals but would not admit it. When the chimps arrived at this horrible place on March 1, an unqualified veterinarian improperly sedated Kermit and then left him unattended in his small transport cage. Kermit's head slumped over and he suffocated. Kermit trusted people to care for him and in the end he was betrayed. The people responsible have yet to accept responsibility. Until all humans recognize that the lives of chimpanzees have value independent of people's self-interests, ideological commitments, or egos, more unnecessary deaths will occur. Kermit's death was preventable and tragic.
Stanford, C. B. 2000. The brutal ape vs. the sexy ape? American Scientist 88, 110-112.
Stanford noted data which indicates bonobos are not obviously more sexual than chimps, that about half of the inter-community encounters observed in one population were aggressive, and that extensive meat-eating and meat-sharing have now been observed in bonobos.

Bonobos are awesome, chimps can be too, but they can also be very dangerous and mean. Humans seem to have traits very similar to both - we have the violent and the loving sides to us - often in the very same person. It's like we're trapped between the two different basic behavioral patterns of these two species.
I noticed those pictures came from the Maryland Zoo (formerly the Baltimore Zoo). It's nice to see they apparently now have a habitat for their primates. When I was growing up in Baltimore ('70s and '80s), they had a horrifying "Monkey House," with all manner of monkeys and apes packed into tiny crates and cages behind glass. I remember one particularly sad, sad orang. who would just sit there glumly in his prison cell staring eternally at the ground in front of him. That sort of thing just doesn't fly anymore, it was way too cruel.
The elephant house was a similar horror when I was a kid, with one, lone magnificent beast in a big cage, with one of its legs shackled by a massive chain. The first habitat area the zoo made was for their lions, and it was fantastic. They had also been in small cages, but in the new habitat they could roam around and run and play and were much, MUCH happier. There were sections for other African animals, too: giraffes, I particularly remember.

Bonobos are a chimpanzee. They are both Pan. There are two common chimps and one bonobo type.
Why would you need to be on a "team?"
What you are seeing here is that our closest relative species span the same cultural spectrums that we do.
However what I find most interesting is that regardless, neither species shows a signficant tendency towards generational advancement. In both species, males don't pass along information.
By that I mean, if you teach language to either male Pan types, they don't teach it to any other member even if it is their children. Females will sometimes pass knowledge on.
In either of these models of gender-bias, the amount of information passing from generations remains fairly consistently similar. Neither is showing any advantage over millions of years.
There is a lesson in that me thinks.
