Unraveling the Bonobo's Genome, and its Secrets


Ulindi, a female bonobo at the Leipzig Zoo in Germany, has had her genome sequenced, researchers report today (June 13), making bonobos the last of the great apes to have their genomes mapped. The resulting genetic code may help unlock the secrets that separate humans — physically, intellectually and behaviorally — from our closest primate relatives.

Bonobos are often seen as the chimpanzee's peaceful cousin. The two primates look very similar and are very closely related, but for some reason chimps resolve conflicts with war while bonobos prefer sex to resolve arguments. Previous studies have also shown that bonobos are more generous with food than chimps are.

"Bonobos and chimpanzees are very different in their behaviors," study researcher Kay Pruefer, of the Max Planck Institute for Evolutionary Anthropology, in Germany, told LiveScience. "While we are not yet able to look at the genome and know why that is, it's important to know the differences between bonobos and chimpanzees to tease apart what genes might be responsible for that."
