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.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闹鬼网红屋犯罪现场调查：迈阿密 第三季叛逆青春校园第二季奥斯威尔亲爱的孩子们飞女四人组金龟子无情的战线国语大卫·伯恩的美国乌托邦美男子难忘的夏天1960酒人传奇结婚攻略理发店情缘神秘岛结婚吧黑市大企业第二季田间的少年第二季假戏真做尝试第一季危机之地国语家宇家宙穿书自救指南 第一季天堂岛疑云：圣诞特辑2022十分钟年华老去：小号篇凤飞飞烤肉店破茧2国语
