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.金燕子1968毒祸2开学悸深圳合租记姿态第一季挪威的维京人第一季紧急救命3新生鬼猛腳火线谁是凶手没有输给美国的男人～混蛋首相吉田茂～人狗对对碰高校舰队剧场版乔老爷上轿水果篮子 第一季雨中的女人诸天纪·动态漫画橡树旭日婚礼难以忘怀网络犯罪调查 第二季4x4湖群狗党联邦调查局第六季好梦连床诸神的黄昏第一季哥伦布传沉睡的男人大南迁妈妈，不当你的女儿可以吗？下一站，说爱你高卢英雄：中国大战罗马帝国女子高中生真心话太冒险2018杜什一家2至高指令Big Order告诉你们什么是Hip Hop蓝色的花断裂2019野姑娘永不放手西部铁血风云边缘追缉令女同学男同学
