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.顶香凯文·哈特：管他呢大猫种族情深纳什维尔小镇大街蝙蝠侠与哈莉·奎恩飘雪六月天初代吸血鬼第二季弗里达降龙大师浒门客栈第一季的士速递4国语助产士2022盂兰神功（国语版）孤独社畜弥留之国的爱丽丝 第二季七武士2004f4沙胆妹移动迷宫2花这样红古惑女之决战江湖完全陌生2016胭脂错2011一地鸡毛住在清潭洞知法犯法瓦莱里娅要结婚了异兽她在路上怪物转生我的傻瓜老婆火力少年王之传奇再现续集二十世纪快车乔安你好（越南语版）少帅传奇午餐女王七妹
