The Trail Continues Ever Eastward

As previously mentioned, some 31,200 years ago, part of the Clan branched north while my ancestor countinued east. That is to say, my ancestor who is referred to in genetic genealogical terms as The Most Recent Ancestor,1 for the purpose of this story, he is synonomous with my ancestor. So, at this point my ancestor forms the new haplogroup sub lineage O2 (also known by its genetic marker, O-M175).

As this was the time when glaciers were at their thickest, my ancestor's nomadic clan had to contend with thick year-round ice sheets, frigid climate, and dwindling hunting and foraging spaces.

Not surprisingly, caves were sought for shelter. Ice Age cave art has been found throughout Asia. In one Indonesian cave, a depiction of a human hand is at least 40,000 years old. It was made by someone pressing their palm and fingers flat against the ceiling and spraying red paint around them. Other items found in Southeast Asian caves shells were worn as jewelry. They include disc-shaped beads made from the teeth of a pig. Also found were pendants fashioned from the finger bones of the possum-like creature.2

Other items found in caves included these fine needles. They are examples of the skill my genetic ancestor needed to hollow out a tiny hole. With such needles, he sewed and clothed himself with animal hides and leather. These particular needles are about 26,000 years old. By then they were weaving plant fibers to make cords and perhaps baskets. This localtion also yielded earrings, animal teeth with holes in them for stringing, fishbones, ocean shells, stone beads, and bones carved in particular ways.

As the following pages will describe, much of Southeast Asia during this time was above sea level. This allowed early humans to spread through Southeast Asia. As a result, haplogroup O2 (O-M175) appears in 80-90% of all men in East and Southeast Asia. The darker shaded areas on the map show the greater areas of the O-M175 population. This sub lineage is almost exclusive to the region. As one of the four dominant haplogroups in East Asia, O-M175 is the largest.

Yet, O-M175 lineage is almost nonexistent in Western Siberia, Western Asia, Europe, and Africa. Also, it is completely absent from the Americas. The dominance of O-M175 in East Asia is shown in the shaded area.
