This group first appeared about 50,000 years ago and is one of two African lineages defined by the presence of the differing YAP gene. It accompanied M130 populations on the great migration tracing the coastal arc along the Southern Arabian peninsula, through India, Sri Lanka, South Eat Asia and Australian.
M174 appears in populations in the Andaman Islands near southeast Asia though no longer in India. It also occurs highly in Japan at over 40 percent.
Later on the M174 peoples from Mongolia moved to Tibet where it is common today.
