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影院欢爱小屋第一季内部战争2020老水仙我是僵尸第三季永远十六岁也许很突然，明天我要结婚了警之光第三季古宅心慌慌超能现代人玛丽和马克思警察夫人2神椿市建设中。神机奇缘亨利·休格的神奇故事同居损友翩翩起舞的姑娘爱就爱了千岁血君潇洒一回37秒男子高中生的日常真人版穿越西伯利亚龙霸天下1992毕业狂欢夜木兰：横空出世霸王花总动员
