简介 In "Birth of Humanity," the second part of the three-part series "Becoming Human," NOVA investigates the first skeleton that really looks like us–"Turkana Boy"–an astonishingly complete specimen of Homo erectus found by the famous Leakey team in Kenya. These early humans are thought to have developed key innovations that helped them thrive, including hunting large prey, the use of fire, and extensive social bonds. The program examines an intriguing theory that long-distance running–our ability to jog–was crucial for the survival of these early hominids.
