Churchill believes that
human behavior is
actually something of a mosaic of traits demonstrated by
chimpanzees and bonobos.
But there are
actually two species of apes that are this closely related to
humans: bonobos (Pan paniscus)
and the common
chimpanzee (Pan troglodytes).
After analyzing
human DNA from several populations around the world
and examining primate genomes dating back to the shared ancestor of both
humans and chimpanzees, researchers reached a striking conclusion that several gene variants linked to schizophrenia were
actually positively selected
and remained largely unchanged over time, suggesting that there was some advantage to having them.
Still, fully understanding the genetic differences between
humans and chimps will require
actually getting inside the
chimpanzee's mind.
Despite the explosive growth in size
and complexity of the
human brain, the pace of evolutionary change among the thousands of genes expressed in brain tissue has
actually slowed since the split, millions of years ago, between
human and chimpanzee, an international research team reports in the December 26, 2006, issue of the journal, PLOS Biology.
