Where did we come from? What makes us human? 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. The program explores the fossil of "Selam," also known as "Lucy's Child." Paleoanthropologist Zeray Alemseged spent five years carefully excavating the sandstone-embedded fossil. NOVA's cameras are there to capture the unveiling of the face, spine, and shoulder blades of this 3.3 million-year-old fossil child. And NOVA takes viewers "inside the skull" to show how our ancestors' brains had begun to change from those of the apes. Why did leaps in human evolution take place? "First Steps" explores a provocative "big idea" that sharp swings of climate were a key factor.鸽子隧道情理法的春天第五季猜·情·寻绝望主妇第二季极品女士第三季蒙眼缉凶37次想你好奇心摸金笑尉(下)简爱森林人鬼来了闺中蜜友枫树大道谋杀案萤之光第二季复制贝多芬恋の墓亚当有四子封魔纪之赤雷传宇宙追缉令英语总统的女儿爸妈二选一播种幸福的人WeWork兴衰史猪标一族 粤语看不见的城市冒牌神医狂飙支队小戏骨：黄飞鸿蛰伏圣女魔咒第三季愤怒的黄牛2021雨女第二季小偷阿星马拉多纳33分钟侦探迷失太空1998意大利任务冬2015海大鱼坂上之云第二部飞蛾日记圣诞奇迹
