Mitochondrial DNA (maternal lineage) seems to point to western and central Africa
As I posted last week, Y-DNA (paternal lineage, Haplogroup A00) seems to point to western Africa, near Bioko.
Mitochondrial DNA (maternal lineage, Haplogroup L1) seems to point to more or less the same part of Africa:
Human expansion: Bioko --> west Africa --> all parts of planet Earth.
(With the large brain, evolved due to marine DHA, Homo sapiens could go anywhere.)
