“…Applying the same approach to the extant M and N lineages, which comprise all the mtDNA diversity in the rest of the world, gave a coalescence date of around 50–65 kya that has been considered as the time frame for the out of Africa dispersal of modern humans [24, 25]. These phylogenetic inferences are at odds with dates obtained from the fossil record that point to the presence of modern humans around 100 kya in the Levant [26], and in southern China [11, 27–29]. The usual genetic explanation for this discrepancy is that these fossils have not left any genetic contribution to extant humans at least from a mtDNA maternal perspective.…”

Carriers of mitochondrial DNA macrohaplogroup R colonized Eurasia and Australasia from a southeast Asia core area

BackgroundThe colonization of Eurasia and Australasia by African modern humans has been explained, nearly unanimously, as the result of a quick southern coastal dispersal route through the Arabian Peninsula, the Indian subcontinent, and the Indochinese Peninsula, to reach Australia around 50 kya. The phylogeny and phylogeography of the major mitochondrial DNA Eurasian haplogroups M and N have played the main role in giving molecular genetics support to that scenario. However, using the same molecular tools, a northern route across central Asia has been invoked as an alternative that is more conciliatory with the fossil record of East Asia. Here, we assess as the Eurasian macrohaplogroup R fits in the northern path.ResultsHaplogroup U, with a founder age around 50 kya, is one of the oldest clades of macrohaplogroup R in western Asia. The main branches of U expanded in successive waves across West, Central and South Asia before the Last Glacial Maximum. All these dispersions had rather overlapping ranges. Some of them, as those of U6 and U3, reached North Africa. At the other end of Asia, in Wallacea, another branch of macrohaplogroup R, haplogroup P, also independently expanded in the area around 52 kya, in this case as isolated bursts geographically well structured, with autochthonous branches in Australia, New Guinea, and the Philippines.ConclusionsCoeval independently dispersals around 50 kya of the West Asia haplogroup U and the Wallacea haplogroup P, points to a halfway core area in southeast Asia as the most probable centre of expansion of macrohaplogroup R, what fits in the phylogeographic pattern of its ancestor, macrohaplogroup N, for which a northern route and a southeast Asian origin has been already proposed.Electronic supplementary materialThe online version of this article (doi:10.1186/s12862-017-0964-5) contains supplementary material, which is available to authorized users.

“…The recent paleogenetic discoveries of limited introgression in the genome of non-African modern humans, of genetic material from archaic, Neanderthal [3, 4] and Denisovan [5–7] hominins has been solved adding a modest archaic assimilation note to the replacement statement [8]. In the East Asia region however, the alternative hypothesis of a continuous regional evolution of modern humans from archaic populations is supported by the slow evolution of its Paleolithic archaeological record [9] and the irrefutable presence of early and fully modern humans in China at least since 80 kya [10–12]. Moreover, recently it has been detected ancient gene flow from early modern humans into Eastern Neanderthals from the Altai Mountains in Siberia at roughly 100 kya [13].…”

Carriers of human mitochondrial DNA macrohaplogroup M colonized India from southeastern Asia

et al. 2016

BackgroundFrom a mtDNA dominant perspective, the exit from Africa of modern humans to colonize Eurasia occurred once, around 60 kya, following a southern coastal route across Arabia and India to reach Australia short after. These pioneers carried with them the currently dominant Eurasian lineages M and N. Based also on mtDNA phylogenetic and phylogeographic grounds, some authors have proposed the coeval existence of a northern route across the Levant that brought mtDNA macrohaplogroup N to Australia. To contrast both hypothesis, here we reanalyzed the phylogeography and respective ages of mtDNA haplogroups belonging to macrohaplogroup M in different regions of Eurasia and Australasia.ResultsThe macrohaplogroup M has a historical implantation in West Eurasia, including the Arabian Peninsula. Founder ages of M lineages in India are significantly younger than those in East Asia, Southeast Asia and Near Oceania. Moreover, there is a significant positive correlation between the age of the M haplogroups and its longitudinal geographical distribution. These results point to a colonization of the Indian subcontinent by modern humans carrying M lineages from the east instead the west side.ConclusionsThe existence of a northern route, previously proposed for the mtDNA macrohaplogroup N, is confirmed here for the macrohaplogroup M. Both mtDNA macrolineages seem to have differentiated in South East Asia from ancestral L3 lineages. Taking this genetic evidence and those reported by other disciplines we have constructed a new and more conciliatory model to explain the history of modern humans out of Africa.Electronic supplementary materialThe online version of this article (doi:10.1186/s12862-016-0816-8) contains supplementary material, which is available to authorized users.

“…Extreme rainfall with storms were also recorded in the cave deposit of Shuijinggong Cave in Guangxi during MIS5a (Zhang et al, 2013), supporting our assumption of intense rainfall at this interval. It is worth noting that this sudden shift occurred during the hominin occupation of Luna Cave (127-70 ka; Bae et al, 2014) and almost coincide with the presence of hominin in Huanglong Cave (101-81 ka; Shen et al, 2013) and Fuyan (120-80 ka; Liu et al, 2015).

Precipitation variations deduced from speleothem stable oxygen isotopes (δ18O) have long been debated in monsoonal China. The magnetic property in speleothems is interpreted to be related to regional precipitation and can therefore offer reliable information of regional precipitation variations. Here we present a speleothem from southern China to explore the magnetic signals in speleothems and to reconstruct regional precipitation in hominin‐occupational area in southern China during MIS5. Saturation magnetization (Ms), which represents the magnetic mineral concentrations, is used as an indicator of effective rainfall variations. The precipitation inferred from Ms increased sharply in the period prior to 80.3 ka before present, followed by a drop to precipitation anomaly afterward, indicating that regional precipitation varied greatly during the hominin‐occupied interval in southern China. Power spectrum analysis of Ms values shows significant ~205‐, ~90‐, ~77‐, and ~64‐year periodicities, suggesting that the solar activity may play an important role in precipitation variations in southern China during the MIS5a/4 transition.
