Haplogroup M122

 

This haplogroup appeared around 10,000 years ago and follow a genetic footprint from the east Asian agriculture. This is assumed because it is widely considered that rice farming techniques were carried by a unique population that grew and expanded rather than spreading from culture to culture.

M122 is prevelant in more than half of all male Chinese which defines them as descendants of the rice farmers. The lineage is commonly found in East Asia, namely China and Taiwan and in lesser frequencies in Tahiti and Indonesia.

A population boom surround the distribution outlines of M122 which began in China and spread East and South. Areas include Taiwan, Japan and Southeast Asia and correlate with the evidence for the spread of rice agriculture.
