INTERESTING HAP@ Deb. HERES WHAT 23 and me says concerning L3f.... You also wanna check L3e5 which can also be found in Chad!
L3f branched off the main L3 haplogroup in eastern Africa an estimated 40,000 to 50,000 years ago. It is still found at levels of about 5% in Sudanese and Ethiopian populations. The haplogroup has also spread across the Red Sea to the Arabian peninsula, Iraq and other parts of the Near East.
Between about 20,000 and 30,000 years ago, L3f further diversified into a pair of daughter haplogroups, L3f1 and L3f2. L3f1 appears to have arisen in eastern Africa and moved westward before the peak of the Ice Age about 20,000 years ago, when the Sahara Desert expanded and rendered much of the northern part of the continent uninhabitable. Today the haplogroup is commonly found among the Yoruba and Fulbe populations of western Africa, and in African-Americans who are descended from them.
Haplogroup L3f2 originated in the Chad Basin of northern-central Africa, where it has been largely confined since then. It has not been detected in African-American populations, an indication that the Atlantic slave trade did not reach as far inland as present-day Chad and Niger.
