L2 individuals are found in sub-saharan Africa and like their L1 predecessors, they also live in Central Africa and as far south as South Africa. But where the L1/L0 peoples remained predominantly in East and Southern Africa, my ancestors broke off into a different direction, West. This L2 line is predominantly African-Americans. Not much is known about this genetic mutation and much genetic sampling is going on right now in West Africa and the United States to determine where, how and when this group emerged. It appears that although this is part of the migration my group (ultimately haplogroup X) did not follow this line.
