Pan paniscus
Bonobos share about 98.7 percent of our DNA and, with chimpanzees, are our two closest living relatives. Yet where chimps resolve conflict with violence, bonobos are famous for resolving it with contact — greeting, grooming, and sharing food between strangers.
Female coalitions sit at the top of bonobo society, and troops of up to 100 individuals merge and split freely through the rainforest. The species lives nowhere else on Earth but the forests of the Democratic Republic of the Congo, where poaching and habitat loss keep it Endangered.
