[/qb][/QUOTE]I don't know. Of the outside of Africa genetic component, only the 'North African' component has been dated satisfactorily. See the paper you posted in the OP. Yes, haplogroups have been dated but its not clear, for instance, which Near Eastern haplogroup is associated with what segment of genome-wide near eastern ancestry. What I mean is in Henn et al the Near Eastern ancestry is green, but because the same Near Eastern haplogroups were introduced in recent and ancient times, you don't know how much of this green component can be correlated with recent or ancient Near Eastern haplogroups like NRY J1 and G.
