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.星空影院桃花影院九九影院私人影院樱花影院星辰影院青柠影院神马影院三妹影院牛马影院金牌影院英伦式丑闻第三季狗狗监护权又快又贱又失控五个单身汉东北恋哥2对你爱不完乡医情冤家宜解不宜结黑帮之境升级新朱门恩怨第三季滴血红宝石了不起的D小姐印度连环杀手档案：德里屠夫第一季鸿运女大当家如珠如宝的人生化身永远的831掌脸说唱王戴夫 第三季骇人命案事件簿第二十二季宝贝大盗第一季The Wedding Veil Legacy咒怨2(美版)佐贺偶像是传奇 卷土重来虚线的恶意奇妙博物馆
