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
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.
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.
