New study on mitochondrial Eve and the first migrations of HAM: Genetic evidence on the origin of sapiens:

Tree of haplogroup LO mtDNA                                                                                             Schematic representation of the most important migrations involving the haplotype LO

 

Teresa Rito, Martin B. Richards, Veronica Fernandes, Farida Alshamali, Viktor Cerny, Luisa Pereira and Pedro Soares used L1'6 L0 haplogroups and mtDNA clade brothers, according to the results, the authors propose that:

The last common ancestor of modern humans (Mitochondrial Eve) lived in Africa ~ 180 ka ago, at a time of low population.

~ 130 ka ago, coexisted in Africa two distinct groups of anatomically modern humans:

L0 in the South. The ancestors of modern populations Khoe and San.  Within haplogroup L0, are perceptible two migrations from the south to east; One of them, between 120 and 75 ka, represents the first modern dispersal distance detected unambiguously large and could have allowed dispersal of several markers of modernity (L0A, L0B, L0f, L0k).

A second, in the last 20 ka represented by L0D, may have been responsible for the dissemination of the languages Click to eastern Africa, contrary to the view that these Eastern examples are relics of an old distribution, much broader.

L'16 in central and eastern Africa. Included the ancestors of the rest of the current populations.

The first modern human dispersals correlate with climate change, particularly tropical African "mega-droughts" of MIS 5 (135-75 ka) which paradoxi8cally, may have caused the dispersal of populations outside Africa haplogroup L3 makes about ~ 60 ka. Disconcerting is the coincidental timing of the L3 expansion and the coming to East Africa and the L-A L-B markers.
