The deep population history of East Asia remains poorly understood owing to a lack of ancient DNA data and sparse sampling of present-day people1,2. Here we report genome-wide data from 166 East Asian individuals dating to between 6000 bc and a
In the following 1,000 years or so, the drainage pattern was in the state of “following its own course” due to the small human population. In the Ming Dynasty (1368-1644), with the alteration of the main rivers, the water resource utilization increased obviously, but the human ...
exacerbating the north-south gap, development fault lines, and the technology divide. the human development index has declined for the first time in 30 years. the world's poor population has increased by more than 100 million, and nearl...
There is linguistic evidence that points either to possible structural relationship or to prolonged contacts between Kartvelian and Indo-European languages in the South Caucasus4,8. This is supported by recently discovered genetic evidence of a ghost population in or near the South Caucasus, which ...

Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer there are more people around at any given time. In fact it is a decrease in death rates...
The Yakuts contrast strikingly with other populations from Siberia due to their cattle- and horse-breeding economy as well as their Turkic language. On the basis of ethnological and linguistic criteria as well as population genetic studies, it has been a
