Male line information: Y-group K*

All members of Y-group K* can trace their Y-chromosomes back to one man who is thought to have lived about 40 thousand years ago, probably in East Africa or Western Asia. This man may have belonged to a group of hunter-gatherers, who were among the first modern humans to migrate from Africa to Eurasia and may initially have made their home in Iran or southern Central Asia. As it happens, some of the other Y-groups found in populations of European and Asian ancestry are also descended from this man (namely, Y-groups L, M, N, O, P, Q, R1a and R1b). However, Y-group K* represents the collection of all the male lines of descent from this man, but do not lead to these other Y-groups.

Today, members of Y-group K* are primarily found in Asia. Males belonging to Y-group K* are present, but rare, in Europe and Africa. Some individuals that were previously classified as K* are now classified as belonging to either Y-group S or T in accordance with the most recent developments in the scientific literature.
