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.梦想森林胜利重逢大转折——鏖战鲁西南时间监狱恋恋书中人2020去死乐乐熊奇幻追踪达人也疯狂现在启示录六斤县长禁食疑案追击巨怪无忧面包店（第三季）午夜食人列车繁城之下成记茶楼不死传说这个男人来自地球：全新纪琉璃之舞追鹰日记英语镇魔大师妈妈向前冲原始森林2022成长教育冰封：重生之门（国语版）三月的狮子：前篇世纪之缘上流恶邻国务卿女士 第三季无价之宝 2011古泷兄弟与四苦八苦最后一次理发这个大叔不太囧畸形人接线员2015天崩地裂 下（国语版）我美妙的西柏林红衣醉拯救你还好吗希望在人间京武火龙我们的知青年代全网最痛恨的男人
