East Asia, consisting of China, Mongolia, the Korean Peninsula and nearby islands, is home to almost one quarter of the world's population and is a haven for various ethnic and linguistic groups. At the same time, archaeological and genetic data indicate that in the past, residents of East Asia were even more diverse than today. In February 2019, a review of anthropologists' research was published on the channel - “Population of East Eurasia according to craniometry data”. Where it is shown that the settlement and population formation of East Asia can be described using two layers of ancestors. The “first layer” consisted of pre-Neolithic hunter-gatherers, and the “second layer” consisted of northeast Asians who had spread throughout Asia since the early Neolithic, contributing to the emergence of the ancestors of many modern populations of East Asia. In a new work, in addition to studying the differences between the ancient populations of the northern and southern parts of East Asia, genetics decided to test the consistency of the two-layer model by analyzing the ancient DNA of twenty-four people from the northern and southern regions of modern China and the islands of the Taiwan Strait, who lived 9500-300 years ago .
