No it is not;

>Re-Examining the “Out of Africa” Theory and the Origin of Europeoids (Caucasoids) in Light of DNA Genealogy
>Haplogroup B is descended from β-haplogroup (and not from haplogroup A, from which it is very distant, and separated by as much as 123,000 years of “lat- eral” mutational evolution) likely migrated to Africa after 46,000 ybp. The finding that the Europeoid haplogroups did not descend from “African” haplogroups A or B is supported by the fact that bearers of the Europeoid haplogroups, as well as all non-African haplogroups do not carry either SNPs M91, P97, M31, P82, M23, M114, P262, M32, M59, P289, P291, P102, M13, M171, M118 (haplogroup A and its subclades SNPs) or M60, M181, P90 (haplogroup B)
>The α-haplogroup which is the ancestral one with respect to both African (left branch) and non-African haplogroups (right branch) arose around 160,000 ybp, and 132,000 ybp gave rise to haplogroup A. Another, quite different branch, had formed a fork, then apparently went through a population bottleneck around 70 - 60 thousand ybp (perhaps the Toba event), and gave rise to β-haplogroup, ancestral to non-African haplogroups, 64,000 ± 6000 ybp.
>Apparently, haplogroup B was initially not of an African ori- gin. It could have migrated to Africa and mixed there with a local Negroid population. A common ancestor of the present- day bearers of haplogroup B lived 46,000 ybp. A similar story had occurred with a group of bearers of haplogroup R1b1 around 4000 ybp, who ventured to the center of African conti- nent during their westward migration along the African Medi- terranean shore, an became a Negroid population having an unusual (for Africa) haplogroup (Cruciani et al., 2010; Klyosov, 2012).
