Melinda A. Yang: 基因分析显示东亚人的两大分支起源 yzout2021-11-27 13:14:15
The very first human beings originally emerged in Africa before spreading across Eurasia about 60,000 years ago. After that, the story of humankind heads down many different paths, some more well-studied than others.
Eastern regions of Eurasia are home to approximately 2.3 billion people today – roughly 30% of the world’s population. Archaeologists know from fossils and artifacts that modern humans have occupied Southeast Asia for 60,000 years and East Asia for 40,000 years.
But there’s a lot left to untangle. Who were the people who first came to these regions and eventually developed agriculture? Where did different populations come from? Which groups ended up predominant and which died out?
Ancient DNA is helping to answer some of these questions. By sequencing the genomes of people who lived many millennia ago, scientists like me are starting to fill in the picture of how Asia was populated.
