Biological anthropologist Dr. Liza Shapiro invites us to rethink how we move in this Hot Science - Cool Talks. From nimble monkeys to powerful apes, primates walk, climb, leap, and scramble in different ways. And humans? We are the odd ones out, but Dr. Shapiro reveals how comparing living primates, studying fossils and using cutting-edge biomechanical analysis can help us understand the deep evolutionary origins of our own unique form of walking.
