- Magdalenian (Paleolithic) origin in the Franco-Cantabrian region some 17-15,000 years ago (incl. possible sub-waves like Tardenoisian/geometric Epipaleolithic).
- Neolithic origin.
- Megalithic origin.
- More or less recent (Iron Age?) arrival, defended by mostly by the fanatics of Indoeuropean continuity.
- Southern or Western Vasconic (Impressed-Cardium Pottery and related cultures, including the Megalithic urheimat in Portugal).
- Northern or Eastern Vasconic (Red-White Painted Ware in the Balcans and later Linear Pottery in Central Europe).

- MK13G117: 223-234-311
- TQ28F256: 223-234-270
- MK11G107: 223-266-289
- 223 describes R, hence counting from the CRS, it should mean L(xR).
- 311 describes L3, hence counting from the CRS it should mean L(xL3).
So all four should be L(xR) and MK13G117 looks like L(xL3).

Human migration north through Africa is contentious. This paper uses a novel palaeohydrological and hydraulic modelling approach to test the hypothesis that under wetter climates c.100,000 years ago major river systems ran north across the Sahara to the Mediterranean, creating viable migration routes. We confirm that three of these now buried palaeo river systems could have been active at the key time of human migration across the Sahara. Unexpectedly, it is the most western of these three rivers, the Irharhar river, that represents the most likely route for human migration. The Irharhar river flows directly south to north, uniquely linking the mountain areas experiencing monsoon climates at these times to temperate Mediterranean environments where food and resources would have been abundant. The findings have major implications for our understanding of how humans migrated north through Africa, for the first time providing a quantitative perspective on the probabilities that these routes were viable for human habitation at these times.

number of sources (including , , , .
The findspots are characterised by Aterian and Middle Stone Age
artefacts such as bifacial foliates and stemmed Aterian points and/or
typical ‘Mousterian’ points, side scrapers and Levallois technology.
Most are represented by surface scatters but where stratified examples
exist these can be shown by dating (OSL and U-series techniques) and
geomorphological setting to belong within MIS 5e , .
As discussed in other occasions, it seems likely that some genetic remnants of those early migrations are still visible in at least some NW Africans.

Location of sites (fig. 3):
Most researchers believe that anatomically modern humans (AMH) first appeared in Africa 160-190 ka ago, and would not have reached eastern Asia until ∼50 ka ago. However, the credibility of these scenarios might have been compromised by a largely inaccurate and compressed chronological framework previously established for hominin fossils found in China. Recently there has been a growing body of evidence indicating the possible presence of AMH in eastern Asia ca. 100 ka ago or even earlier. Here we report high-precision mass spectrometric U-series dating of intercalated flowstone samples from Huanglong Cave, a recently discovered Late Pleistocene hominin site in northern Hubei Province, central China. Systematic excavations there have led to the in situ discovery of seven hominin teeth and dozens of stone and bone artifacts. The U-series dates on localized thin flowstone formations bracket the hominin specimens between 81 and 101 ka, currently the most narrow time span for all AMH beyond 45 ka in China, if the assignment of the hominin teeth to modern Homo sapiens holds. Alternatively this study provides further evidence for the early presence of an AMH morphology in China, through either independent evolution of local archaic populations or their assimilation with incoming AMH. Along with recent dating results for hominin samples from Homo erectus to AMH, a new extended and continuous timeline for Chinese hominin fossils is taking shape, which warrants a reconstruction of human evolution, especially the origins of modern humans in eastern Asia.
|The Huanglong teeth (various views)|
The seven hominin teeth from Huanglong Cave have been assigned to AMH
mainly because of their generally more advanced morphology than that of H. erectus and other archaic populations (Liu et al., 2010b),
especially in terms of the crown breath/length index. These teeth also
lack major archaic suprastructural characteristics listed by Bermúdez de Castro (1988)
for eastern Asian mid-Pleistocene hominins, such as “strong tuberculum
linguale (incisors), marked lingual inclination of the buccal face
(incisors and canines), buccal cingulum (canines and molars), wrinkling
(molars), taurodontism (molars), swelling of the buccal faces (molars)”
(Tim Compton, Personal communication). However, in their roots, these
teeth still retain a few archaic features, being more robust and
complicated than those of modern humans (Liu et al., 2010b).
The new timeline for human evolution in China is in disagreement with
the molecular clock that posits a late appearance for AMH in eastern
Asia (e.g., Chu et al., 1998).
