Historical rice farming in China linked to contemporary polygenic score differences

Chen Zhu, Thomas Talhelm, Yingxiang Li, Gang Chen, Jiong Zhu & Jun Wang
Following domestication in the lower Yangtze River valley 9,400 years ago, rice farming spread throughout China and changed lifestyle patterns among Neolithic populations. Here we report evidence that the advent of rice domestication and cultivation may have shaped humans not only culturally but also genetically. Leveraging recent findings from molecular genetics, we construct a number of polygenic scores of behavioural traits and examine their associations with rice cultivation based on a sample of 4,101 individuals...
