Description: 遗传学家施温提·柏保通过介绍了一项大规模的世界范围内的研究，展示了早期人类中走出非洲之后与尼安德特人交配的DNA证据（是的，我们中的不少人拥有穴居人的DNA）。他解释了小小一片小指骨如何足以分辨出一个全新的类人人种。

Genetic studies show that every human alive today descends from a small group that left Africa around 50,000 years ago. DNA evidence proves that early modern humans interbred with Neanderthals and other now-extinct relatives, leaving traces in our genomes. A tiny fragment of bone even led scientists to discover the Denisovans, an entirely new human species. Despite these ancient encounters, there are almost no absolute genetic differences between people from different continents.
