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神经马龙第二季五朵金花和我结婚吧有招没招之爱情达人情萦田纳西替代者2猎豹你是我的春天2021街头美食斗士动态漫画·开局重生一千次第二季花间提壶方大厨第一季11-12-13至死不渝兴风作浪3一起同过窗第三季番外魔法俏佳人 第四季2016：夜之尽头整蛊之王侠女：剑的记忆能面检察官飞哥战队战狼·战狼闪婚老公太给力O记实录之抢匪少年歌行世界尽头LALIGA 西甲全纪录
