1万年前的欧洲人就是金发碧眼吗?
印度几千年的种姓制度造就了怎样的结果?
人类是起源于非洲还是世界各地分别演化出来的?
尼安德特人、丹尼索瓦人真的被我们的祖先完全消灭了吗?
你知道有很多“幽灵人群”活在我们的DNA里吗?
传统的考古学、语言学构建的人类演化史留下了大片大片的空白。幸好,这已经成为过去时。古人类DNA测序正在掀起一场革命,重新谱写一曲50万年的人类迁徙演化之歌。
大卫·赖克从古人类遗骨中提取DNA,从基因层面还原了人类祖先的面貌。原来,我们的先祖在地球上已经上演了几百万年的“权力的游戏”:在任何一片大陆上,人群都经历了多次毁灭与更迭;所有当代人的祖先都拥有一段复杂难辨的混血史,没有人是“纯种”;千百万年来的种族、性别、阶层不平等在我们每个人的DNA里都留下了深深的刻痕。
面对DNA序列分析这种最先进可靠的技术,我们以前所以为的所有关于人类演变的知识,凡是跟这本书所代表的当前科学理解不一样的,都只能改写。因此,这场革命给了两个问题迄今最为清晰的答案:我们是谁,我们从哪里来。
Massive technological innovations now allow scientists to extract and analyze ancient DNA as never before, and it has become clear–in part from David Reich’s own contributions to the field–that genomics is as important a means of understanding the human past as archeology, linguistics, and the written word. Now, in The New Science of the Human Past, Reich describes just how the human genome provides not only all the information that a fertilized human egg needs to develop but also contains within it the history of our species. He delineates how the Genomic Revolution and ancient DNA are transforming our understanding of our own lineage as modern humans; how genomics deconstructs the idea that there are no biologically meaningful differences among human populations (though without adherence to pernicious racist hierarchies); and how DNA studies reveal the deep history of human inequality–among different populations, between the sexes, and among individuals within a population.
