ORIGINS

It is believed that haplogroup X diverged from haplogroup N. Around 30,000 years ago it then sub-divided into two groups known as X1 and X2.

Sub-group X2 appears to have undergone extensive population expansion and dispersal around or soon after the last glacial maximum, about 21,000 years ago. It is more strongly present in the Near East, the Caucasus, and Mediterranean Europe; and somewhat less strongly present in the rest of Europe. Particular concentrations appear in Georgia (8%), the Orkney Islands (in Scotland) (7%), and amongst the Israeli Druze community (27%). Subclades X2a and X2g are found in North America, but are not present in native South Americans.[5]


How did haplogroup X, a Middle Eastern gene, find itself in the region of the Great Lakes 10,000 years ago and not in South America, nor in ancient Siberian cultures,not in Alaska or alongside the west coast of the United States?

This requires further inquiries.
