I have been saying all along that 1. There is no race. 2. Europeans are a subset of Africans being depigmented Africans 3. There were essentially two wave OOA. 4. The migration route to Europe was NOT via the Levant but North Africa to southern Europe 5. My interpretation is ALWAYS correct 6. Modern West Africans are young and new to West Africa. They are from East Africa(part of the Neolithic package) 7. modern West Africans carry admixture from an older African population that may be part of WHG of Europe 8. Simultaneous reduction of Luhya and MKK with an increase of West Africans. That is why YRI are 3rd closest to AEians. 9. All European lineage is African 10. Africans took their dogs to Scandinavia 11 I wasted my years educating some of you fools when this paper has been out since 2011. (Sic)
I love being right. Lol! Let them keep looking in the Steppes Reich, you "lying European". . But these researchers know that I am right. That is why they play these games of differential sampling. Excluding Certain African populations when it makes the best sense to INCLUDE these said populations. It is a game and they know the truth. Don't believe me? Rosenberg knew it since 2002. Here McEvoy adds fuel to flame and proves xyyman right....once again
----- Human population dispersal ‘‘Out of Africa’’ estimated from linkage disequilibrium and allele frequencies of SNPs - Brian P. McEvoy,
We use the empirically observed genetic correlation structure (or linkage disequilibrium) between 242,000 genome-wide single nucleotide polymorphisms (SNPs) in 17 global populations to reconstruct two key parameters of human evolution: effective population size (Ne) and population divergence times (T).
Estimates of divergence times between European–African and East Asian–African populations are inconsistent with its simplest manifestation: a single dispersal from the continent followed by a split into Western and Eastern Eurasian branches. Rather, population divergence times are consistent with substantial ancient gene flow to the proto-European population AFTER its divergence with proto-East Asians, suggesting distinct, early dispersals of modern H. sapiens from Africa. We use simulated genetic polymorphism data to demonstrate the validity of our conclusionsAGAINST alternative population demographic scenarios.
We explored human LD patterns using approximately 242,000 SNPs across the genome in 17 population samples from across the globe. We used these to reconstruct two key parameters of human evolution: effective population size (Ne) and population divergence times (T), and through these track the emergence and dispersal of our species ‘‘Out of Africa’’ and beyond. In addition, we used simulated genetic data to evaluate the performance of parameter estimators across a range of population demographic models.
However, there is evidence for a small increase in the West African Yorubans (YRI) ;8 KYA, coinciding with declines in the East African Maasai (MKK) and Lubya (LKK) populations at the same time (Figs. 2, 3B). From ;25 KYA, all non-African populations start to expand, and distinct growth trajectories become apparent moving toward the present, reflecting the emergence of each population as a separate entity (Fig. 2).
This provides a clear picture of the historical relationship between populations with three broad groupings apparent: Africans, East Asians, and Europeans. Early human dispersal patterns can be inferred through estimates of T between these three main groups. The average TF estimate between these African and European populations is ;36 KYA, ;44 KYA for Africans and East Asians, and ;20 KYA between East Asians and Europeans
Under this scenario, the divergence times of these two groups relative to Africa would be expected to be similar. Both TF and TLD, two T estimators calculated by different means from the same data, ***consistently*** demonstrate a significantly more recent relationship between Europe and Africa than between East Asia and Africa. Using simulated populations, we show that under the single-wave ‘‘Out of Africa’’ model,
While the exact bias is difficult to estimate (Sved et al. 2008), it appears that post-divergence migration rates from Africa to Europe would need to be approximately CONSTANT because we observe consistent ratios of TF and TLD at different genetic distances. Thus, the observations are suggestive that GREATER MIGRATION TO EUROPE FROM SUB-SAHARAN AFRICAN HAS BEEN A LONG-TERM PHENOMENON. Y-chromosome and mtDNA lineages are generally highly differentiated between continents, making them powerful genetic markers of intercontinental migration. Most of the lineages that are characteristic of sub-Saharan Africa are absent in Europe (and vice versa) (Cavalli-Sforza and Feldman 2003; Underhill and Kivisild 2007). However, the coalescent time and geographic distribution of the Y-chromosome E3b (E-M215) haplogroup points to a late Pleistocene migration from Eastern Africa to Western Eurasia via the Nile Valley and Sinai Peninsula ;20–25 KYA (Cruciani et al. 2004, 2007; Luis et al. 2004).
However, these Y chromosomes are concentrated in southern Europe (Cruciani et al. 2004), whereas the smaller average divergence times between Europe and Africa relative to East Asia and Africa are still readily apparent across each individual northern European sample population (Supplemental Table 2). This suggests that the discrepancy has, at least partially, an even earlier and more pervasive origin, being established prior to the appearance, and consequent migration tagging ability, of the current range of mtDNA and Y-chromosome haplogroups.!!!!!!!!!!!!1
which look at divergence times in West and East Eurasian populations simultaneously, point to a more complex ‘‘Out of Africa’’ scenario. Firstly, they suggest a substantial gap between African/Eurasian and West/East Eurasian divergence (;20 KYA from TF estimates), indicating an appreciable pause between leaving Africa and departure for East Eurasia. Secondly, they support further early gene flow to the remaining proto-West Eurasian population from Africa after Eurasian divergence, perhaps as a second smaller dispersal (Mellars 2006a). ------

To those who can't follow. They used LD to discern their hypothesis. Eg even in Scandinavia Europe there is a strong connection to sub-saharan Africa. Remember my post on Sami-Berbers? I made it clear that the more intriguing discovery from that study was not the Sami Berber connection but the Sami-Fulani connection which was overlooked and under-discussed in the paper. The Fulani carried the ancestral form of U5b to the Sami's. That was a shocker. Then I followed that up with showing Scandinavian dogs were from West Africa. Davidksi proceeded to delete that entire thread when I showed him up. They don't want to know the truth they are interested in fantasy and fake news. Continued delusion. The last piece of the puzzle is for these "experts" to acknowledge that there was no coastal route migration of East Asians from Africa. Keeping in mind it is now being discovered that south Africans carry more "Asian" markers than West African Bantus. Somehow the migration was across the Indian Ocean incredulous as it may sound. Only explanation is a land bridge. Indonesians did not travel 2000miles across the Indian Ocean in 5ft straw boats to Madagascar. SMH. these delusional Europeans...liars
Oh! And Capra! Remember than discussion on Cape Verdean we had on Davidski. Guess what? The chicken is coming home to roost. Look at the lastest paper that included Cape Verdeans. mtDNA H1c* and R-V88. As I said. Cape Verdeans are the last remnants of that ancient WHG that remained in Africa (blacks with blue eyes) and the new breed of Africans(Neolithics), Light skin Africans with dark eyes.

The land bridge was on land, through Arabia and Central India(Narmada River) during wet times.

I get that you are exaggerating but the dufuna conoe is 27 feet long and 8,000 years old the oldest in Europe is 10,000 or so and of a primitive design by comparison, not saying people necessarily had to travel by boat but I don't doubt the possibility.

@DDEDEN. There is no genetic trace of migration THROUGH Arabia. That is the point. Nein! However there are traces in the populations in Islands off Africa. Seychelles, Soqotra, Madagascar ...even Andamans. They all carry Asian ancestry and lineage.

"The earliest introduction of domestic chickens and black rats from Asia to the east coast of Africa came via maritime routes between the 7th and 8th centuries AD"
"Archaeologists have been debating the timing, mechanisms and social contexts of the arrival of Asian plants and animals to eastern Africa for a long time," explains Dr. Boivin, senior author of the study. The competing models are, on the one hand, a very early arrival of Asian species starting around 3000 BC as suggested by some previous studies, and on the other hand, a more modest, mid-first millennium AD arrival in connection with the archaeologically-confirmed maritime trade routes"
"Excavations in Kuumbi Cave, Zanzibar, Tanzania. Avian remains recovered at this site that were originally identified morphologically as domestic chicken were proven to in fact be native guinea fowl when analyzed with ZooMS, illustrating the benefits of using multiple types of analysis"
Kuumbi perhaps means: ku ~ gua@Malay-Chinese: cave uumbi ~ womb

Pygmies went east along the tropical rainforest belt. They had dome huts of wicker and broad leaves & fire-hardened thrusting spears, and egaliterean cohesive societies, no tents or canoes, but could ford rivers and plausibly invert their huts to make waterproof basket boats/round shields to cross larger water bodies. They may have carried these round shields, to protect against rain, sun & predators. They would have left virtually no artifacts behind, beside cut-marked animal bones, on their nomadic travels.
Waves of other later taller people would not have followed the inner rainforest belt, but rather have followed the edges.

??? your point. By 500AD intercontinental travel was common place.

Quotes from the study: "Further matches were made to four Asian phasianid genera (all members of the order Galliformes): Arborophila, Bambusicola, Polyplectron, and Syrmaticus. The most likely explanation is not that these are Asian imports, but rather that these bones belong to native African genera (NOT YET SEQUENCED) that are more closely related to Asian genera than to other African genera. There are a number of African phasianid genera not in the GenBank database–for example Francolinus and Pternistis–that are potential candidates.
The resulting p values cannot be interpreted strictly as the probability that a library belongs to the corresponding genus, but rather as the probability that a library belongs to a species most closely related to this genus, since our database does not contain all extant bird genera. However, it does contain all Gallus species; furthermore, all the potential African genera that could be mistaken as Gallus–for example, Numida, Francolinus, or Pternistis–are either represented in our custom database, or have closely related genera in our database
Reference material for eastern African native rodents was not available at the time of analysis, so comparisons could only be made with island Southeast Asian and invasive species,"

Yes because you look at things with a unique backwardsian perspective so we have to see how you are interpreting this to see if it corresponds with what is quoted
We have to see if you understand what you are reading
