Description: 遺傳學家Svante Paabo分享規模遍及全球的研究成果，並說明早期人類在離開非洲後和尼安德塔人交配的DNA證據（是的，大部份的我們有尼安德塔人的DNA）。他也說明由一塊幼兒指頭小小殘骸如何足以辨識出一個前未發現的新人種。

Svante Paabo：人體內之尼安德塔人基因線索

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.
