Okay, so we’re not as hirsute and we don’t routinely brachiate through trees, but in what other ways are we different from chimpanzees? With a map of the chimp genome in hand, scientists are closer to answering that question. Join us for a trip to the primate house as we explore in what way the last 2% of DNA separates us from our swinging cousins. Primatologist Frans de Waal reminds us that we’re just as closely related to bonobos, the left-bank primates. And, lest you forget your marine heritage, discover which genes you share with… sea urchins.
