Where did we come from?它赢​在细节，很耐看。​What makes us human?作品类型​为记录片，2009年推出，千万别​错过。An explosion of recent discoveries sheds light on these questions, and NOVA’s comprehensive, three-part special, “Becoming Human,” examines what the latest scientific research reveals about our hominid relatives. Part 1, “First Steps,” examines the factors that caused us to split from the other great apes.
