影片别名：Becoming Human Part 1: First Steps / PBS "NOVA" Becoming Human
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.对家庭实在不应该有太多怨言，祖先最早也只是一个猿演化史告诉我们，人类的方式是不断变好不断攀升，而不是苟延残喘得过且过人类天生是适应变化的能家里手站立 脑袋发育 褪去体毛 情感 语言 文化牙齿 阴蛰 骨骼的利用三集分开页面了一并打星。 700万年前的乍得沙赫人，人和黑猩猩的共同祖先。“直立人”生活了约500万年，图尔卡纳男孩，奇特的古猿人特征，性成熟早、幼儿期短从进化成果的角度看反而是劣势。人类（智人）进化成功的最重要变量是气候变化。这一点和“如今气候变暖是大趋势中的一次合理波动”，是讨论全球变暖是很有趣的值得谈及的点PBS.Nova出品，对南猿-能人-直立人-早期智人这几个关键分化点描述较详细，其中对丧失体毛时间的分析很有意思，利用了阴虱与大猩猩虱的同源性和分子钟
