When was OOA first proposed? The very first mtDNA tree in 1983 varied depending on whether one accepts the molecular clock (hence neutral theory). If they assumed the clock , they got OOA. If not, they obtained instead the Out of Asia model. https://t.co/j

@motherlander @carlzimmer Check out the very first paper on mtDNA tree of modern human origins from Cavalli-Sforza lab. Depending on assumptions, the paper presents 2 trees, one rooted in Asia and the other in Africa. The Asia model was reinvented by us 35

@pontus_skoglund @AmandaGHenry @brandonscooper @3rdreviewer @pastramimachine Yes, it does. See Fig 7 legends of the first mtDNA tree in 1983 by Johnson et al: "The tree... shows 2 possible roots, one based on the assumption of equal rates of molecular evol
@shi_huang5 Here they state that it appears mutation rates, or fixation of mutations, appears to be higher in bushmen. https://t.co/De7MrtRaj1
