Yes, this. The divergence of human primates happened before the divergence of chimpanzees and bonobos; we are either equally related to both, or slightly more related to the bonobo, depending on whose genome mappings you find more accurate.

The mythology that humans are more closely related to chimpanzees than bonobos comes almost completely from sexism among observers. See Frans de Waal's great article (http://www.primates.com/bonobos/bonobosexsoc.html) on the topic.

(Here from James D. Nicoll's flist; we don't know each other, but this is a pet subject of mine so I had to barge in.)
