人类进化1：混沌初开电影免费高清在线观看全集。
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.陌陌影视陌陌影视樱花影院6080影院没好死地狱厨房(美版)第三季金菩萨 金菩薩巴风特妈妈与家族企业九幽寻宝录霸爱总裁僵尸福星仔国语创富二代放手再爱不同的男人圣痕神童2019我哥我嫂绝世情歌本能反应玛拉与盗火者她来找我中华：龙的传人被偷走的女孩第一季全城戒备动态漫画·仙帝归来第二季大蛇2热气球飞行家（原声版）真我人生第一季负重前行幻影车神3：魔盗激情
