Jungle Fever? That's not scientific. Socio-Sexual biased gene flow is the phrase.
Anyway ... Ever have to explain this stuff to an inquisitive Soaps watcher? What am I doing? Population Genetics booboo. I'm writing some thing like: Homesick U6a1 went back to Maghreb taking E-M78 along. M1 homewreckers fled east, led by M78 cheaters. Mashreqi gossipers made the Horn a good looking further place for disgraced M1|M78 to move on.
Homeless Z287 were taken in by Levant mtDNA's. First-generation Z830 mated local women, the only game in town. Second generation M123 was no longer continental African.
But where they're gonna read it I gotta stuffy it all up in jargon only insiders understand or make believe they do.
Say what? Flipper's coming on? Lemme get off the 'net. Mix me another Jamaica Me Happy with that Smith&Cross. Don't forget the Coco Rčal.

True. U didn't migrate from Europe to Africa. It was U6.
I used to think U6 originated in AME (Africa & Mid-East).
Two years ago Rumanian 35k U6 was found. U6 is E Euro in origin per known physical remains but not "Caucasian" as per Maca Meyer.
U6 ←U ←R ←N ←L3.
L3 born in Africa N born in AME R born in Eurasia U born in Eurasia U6 born in Europe
U6a'b'd'c born in Africa. U6's generational offspring are considered not just northern African but a Maghrebi Imazighen ('Berber' speakers) marker. This makes for low level female genetic continuity from before the last Ice Age to the present in the Maghreb al Aqsa. Birth and at least 20,000 years residence make U6 downstream clades indigenous African.
Geneticist reports are in consensus for U6a'b'd' all being born in the Maghreb. U6c seems questionable. Tschad? Canaries?
U6a1 was born further east somewhere between Libya and Sudan.
I feel sorry for people paying Skippy for a so-called African Ancestry test. Skippy labels U6a1 European, a blatant error.
But then relying on Skippy for accurate Africana is a well known stupidity marked by fear of independent thought.

Didn't haplogroup U come from N? Wasn't N being said to have originated in Asia? descendants of Backmigrants that then mutated in Africa.

U guyz is funny, shooting from the hip.
Consult • Secher & Fregel, et al 2014 • Hervella et al 2016 and their references to learn about U6. 2003 Maca-Meyer's where I started. Charactering U6 straight up caucasian like she did is Eurocentric not merely excusable benign unavoidable Eurovision.

So when was R removed as U's immediate upstream forebear? And when did Rumania leave Europe?

Just because U6 was found in Romania 35,000 years ago does not mean it originated there. U6 is between 40 and 50 thousand years old. The oldest human remains in Europe don't go that far back. Most scientists place the first humans in Europe between 40 and 50 thousand years ago. So it is very unlikely that U6 originated there in Romania. More likely is it arose in Africa or even the Levant, but among populations that for all intents and purposes were Africans. And that 35,000 year old sample of U6 is not tied to any modern European. Most likely a wave of R and U carrying migrants arose in Africa at the point of OOA 60,000 years ago. But when you are talking about populations over 40,000 years old this just becomes a case of splitting hairs. All these populations would have been African in every sense of the word at that time and prior.

Thanks you Doug. I just back in... Looking to respond but you did already. Sometimes I wonder if everyone else is a retard on this forum.
What was/is found in Romania is exactly where and what it should be at that time in human history consistent with an African origin. The fools do not see that. Apples and apples guys not apples and oranges. SMH.

Even when the hypothesis makes absolutely no sense I am surprised when the "conscious" ones are gullible to it when they should know better and see through the "sleight of hands". No people ...mtDNA U6* 35,000years ago in Roamania is exactly consistent with an African origin of mtDNA U.
When we sample 35000yo aDNA from Africa and it is confirmed to be a subclade of U6 ONLY then we can safely assume mtDNA U6 is of non-African origin.
As it stands right now we do NOT have comparable samples FROM Africa at this point in time.
But we do have Kefi samples @ 22000ya. mtDNA U/H.?
I hope some of you use what little common sense you have. No Brilliance needed,
Lioness, Oshun and the like get a free pass....wink! I expect better of you ..."conscious"... ones.

Some of you who understand Skoglund and the new aDNA data from North Africa can see the many surpirses.
What mtDNA U6* were white Europeans that backmigrated from Romania then turned black as they entered Africa?
We know North Africans and Levantines were black as all aDNA has shown to this point. We know Luxmanda was really a "Eurasian" living in Tanzania who carried mtDNA L2a. So was she an European-African or an African-European...lol! Such fools.

This seems to be where the discrepancy lies. If someone leaves Africa and comes back, are they NEVER African again from that point forward? Most people here don't seem to deny the distant ancestors to U6 were "Eurasian" which is what I imagine what Eurocentrism is gunning for. Limit "Africanity" to people who never left.

The irony is that you guys are right. U6's people came from Asia. As far as the archaeological correlate of the subclade (U6abcd) that eventually went into Africa, it's probably the Levantine Aurignacian.

Thank you. U cometh from R. U is 2nd step from N.
I'm not saying U6 boarded a flight or set sail directly to Morocco. Of course it crossed thru the part of AME* called SW Asia among other names.
To me since the oldest U6 known is in Roumania for now any other origin is non-parsimonious speculation that could turn out correct by some later unknown find. But for now a an aDNA fossil at hand is worth.
Age, frequency, diversity of U6a'b'd'c seem to weight the African pan of the coalescence and expansion scale. Afaic they're just as indigenous African as those L clades which're younger. The Africa we know is a child of Mid Holocene monsoon withdrawal.
Will add some quotes later unless somebody beats me to it.

I'm saying the subclade that made its way to Africa stopped in the Levant, first. The Romanian individual belongs to another subclade. Both subclades originate with a parent population that migrated from Asia.

Ancient DNA classified as belonging to the U* mitochondrial haplogroup has been recovered from human skeletal remains found in Western Siberia, which have been dated to c. 45,000 years ago.[4]
From Wikipedia
Just because haplogroup U was found in Siberia 43,000 years ago does not mean it originated there. The problem here is that the time depth beyond 43,000 years ago is so great that the odds of finding other older remains with U DNA decreases. But if you have U in Siberia and U in Romania and U in Taforalt, the most logical explanation is that all of these descend from a common ancestral population that lived between Africa, Arabia and the Levant upwards of 50 to 60 thousand years ago, which is right around the time of OOA. The idea that Siberians backmigrated all the way back to Europe and then Africa to re introduce U to the continent is far fetched and illogical.
This also means by extension that the parent of U, which is haplogroup R also likely arose in Africa as well as you are talking about an age of 66 thousand years old.
When it comes to "basal" lineages like U and R the odds are that they arose in Africa among migrating populations or populations that were once more widespread in Africa (ie. in North Africa) but later displaced by environmental and other circumstances (the Sahara pump).

No it isn't. If people migrated out of Africa all over the planet that does not mean genes cannot have mutated outside of Africa and over thousands of years people migrating back into Africa pressured to due so due to the ice age or other reasons.
The idea that mutation and drift did not cause some new haplogroups to form outside of Africa is political

No, a group comprised of men and women migrate to a new location. They get into a war in that new area and they lose the war. They men are killed and the victors take the women. That is one possibility. It doesn't even have to be in large masses because after thousands of years later a small group can multiply into a new group.

Good arguments all around.
A method implied by Swenet will tell us a lot; line up as much of the mitogenomes accessible to ascertain any lineal direct relationships of Roumania & Maghreb.
Meanwhile are the authors misleadingly pointing to PM1 U6 ancestral to U6a'b'd'c? Figure 2. Distribution of the U6 mitochondrial lineages. (A) Phylogenetic analysis and temporal estimates for lineages including the Pestera Muierii-1 (PM1) from the mitochondrial tree.
In lieu of editing my last post here's some relevant Hirbo for some reason last August I took notes on .
Sorry for block of text. If I underscored points it'd only take away from the overall presentation.
" Middle Paleolithic tool industries of northeast Africa, which might have served as transition technology to the Near East, have been broadly classified into two complexes: Nubian that is riverine that probably expanded northward from the Sudan, and the Lower Nile valley complex [586]. The Lower Nile valley complex is described as flexible, which made it possible for its users to adapt and exploit different environments including the desert [586]. The Lower Nile valley complex is considered as a continuation of industry practiced by earlier occupiers of the Nile Valley (from 90 kya), before subsequent transition to Upper Paleolithic industry around 40 kya [586]. Similarity between stone tool technologies dated to between 35-44 kya at Nazlet khater 4 in Egypt and those used at the site in the Levant (Boker Tachtit) [691, 692] serves as evidence of a transition of modern humans from Africa to Eurasia. In fact, archeological findings from several 30 - 50 kyo sites in the Levant have been termed “transitional industries” between the Middle and Upper Paleolithic [29].
The Upper Paleolithic industries thought to be the work of modern humans seem to have appeared somewhat earlier in western Asia than in Europe [29]. Some historians argue that the 40 kya common tradition that marks the behavioral modernity sometimes attributed to Neanderthal (art, personal decoration, ritualized burials, formal bone tools and gift exchange), might represent the expansion of Upper Paleolithic anatomically modern human populations across Europe [393, 685, 693]. Despite the fact that Europe was settled by modern humans by the end of the Middle Paleolithic (by 30 kya) [404, 694], the early European modern human fossil evidence from Mladec (28 kya) [695] exhibit features that support substantial and relatively recent African ancestry [26]. Moreover, a study of comparison in body proportions of skeleton samples from the European Early Upper Paleolithic (30 -20 kya) shows that they cluster with recent African samples rather than European Late upper Paleolithic (19-10 kya) samples indicating that there was some gene flow and/or migration from Africa associated with the emergence of modern humans in Europe [696]. Therefore, the sequence of historical events and archaeological evidence above, indicates that the expansion from Africa into Southwest Asia might have taken place around 40 - 50 kya. This is further supported by anatomically modern human produced tools shared between North Africa and the Near east [697].
During two periods, the African faunal zone seems to have extended briefly into the Near East and allowed modern humans to expand their range out of Africa into southwestern Asia [698] before contracting back [699]. These two periods, about 100 kya and 50 kya, coincide with the initial unsuccessful and the second the later expansion out of Africa, respectively [29, 148, 684, 686]. Therefore, the contiguous area that constitutes part of north Africa, specifically the Nile valley and near East, might have also acted as a corridor of human range expansion from Africa and population contraction back to Africa from 40 kya up to the late Pleistocene (20 kya) [586].
The scenario described above fits the genetic evidence and time period for modern human dispersal from Africa through the northern route [17], mostly by individuals with R0 mtDNA lineages (sub-family of the N-clade). Based on principal components analysis (PCA) of a dataset of 940 individuals from 53 representative global populations typed at ~650,000 SNPs as part of the Human Genome Diversity Project [343], Reich et al., [555] speculated that there was sub-Saharan African gene flow into Europe and the rest of Eurasia. Moreover, based on a novel PCA and clustering method which was used to determine the phylogeny of 1737 complete human mtDNA sequences, Alexe et al., [191] argued that M and N mtDNA clades arose due to two different migration events that represent the previously described southern and northern routes respectively. They [191] further argue that the N carrying population that followed the northern route split along an East-West geographic division, resulting in a western “European R clade” containing the haplogroups H, V, H/V, J, T and U, and an eastern “Eurasian N subclade” containing haplogroups B, R5, F, A, N9, I, W and X. However, considering the distribution pattern of the „Eurasian N-clades‟ in Southeast Asia, the
408 Pacific and the Americas, some of the N clades might have been present in individuals who followed the southern route. Interestingly, the R clades that are found in South/Southeast Asia and the Americas (A, B, F, N9, R5-R11, P and Y) seem to have split off from other R clades that are mainly found in the Near East and Europe about 50-70 kya [190]. Such a scenario may indicate that the N clade split within Africa before its expansion out of Africa. The M haplogroup, whose M1 haplotype is predominantly East African and whose other haplotypes are found in the Indian subcontinent and southeastern Asia, might also reflect a population split just before/or after the out-of Africa migration, with most of the M haplotype carrying populations expanding through the southern route. The TMRCA age estimates based on ~4600 sequences – N=3191, M=1416 (60 from this study and the rest from previously published data) of the N and M haplogroup lineages are 41 – 67 ky (Kivisild et al., [220] 62.11±6.09 ky and Mishmar et al., [178] 47.92±6.98 ky) and 41 – 62 (Kivisild et al., [220] 55.76±4.36 ky and Mishmar et al., [178] 45.11±4.53 ky), respectively (Appendix 7b). These age estimates for the two haplogroups concurs with estimates done using a corrected time-dependent mutation rate based on the entire mtDNA genome using a maximum likelihood method which estimated the TMRCA of the N haplogroup to be 76.92±17.53 ky and the TMRCA of the M haplogroup to be 73.3±9.64 ky [190] (Appendix 7b).
It is still not yet clear whether M and N arose in Africa just before the exodus, or just after it (as indicated by the close relationship and similar ages for M and N (as estimated above), but it is highly unlikely that it happened further east in India as speculated elsewhere [598] based on high diversity of M [412, 600, 700, 701]. The ages of the haplogroups coupled with the distribution pattern of N and M haplotypes described above are consistent with the
409 hypothesis that they diverged prior to migration of modern humans out of Africa or just after it. This time period coincides perfectly with the return to warm, moist conditions in global climate after volcanic ash from the Mt. Toba eruption (which took place 73 kya in modern-day Sumatra) dissipated. The effects of the eruption on the tropics and sub tropics were reduced temperature, precipitation and increased aridity, and may have lasted until 60 kya [393]. It is hypothesized that these events led to a contraction of the human population, reducing genetic diversity and limiting the distribution of human populations to areas with climatically favorable conditions and ecologically stable environments [48, 110, 393]. The climatic conditions improved around 57 kya with increased insolation (solar radiation received) and precipitation in northern Africa [393]. During dry periods, environmental barriers associated with the severity of the Sahara desert could have made the northern route difficult, so it is likely that this route was more suitable during wetter climatic periods [702]; thus the expansion may have been more likely during the wet periods of 43-57 kya [393, 592]. Recent study‟s [703] findings of a crude age estimate (13.6 – 108.4 kya) and distribution pattern of 17q21 inversion (microtubular associated protein tau (MAPT) inversion), mainly across Europe, Central and southwestern Asia and Africa [703], also seem to conform to northern route out-of-Africa human and Neolithic expansion. "
What do you think the discussion is about? Repeating it doesn't clarify anything. Apples and apples is the only way to resolve this.
Because a "dead end" of U6 was found in Romania from 35,000 does mean it originated in Romania ...or the middle East. Might as well make N and all it's sub-clade be of European origin like all those red circles. Even when Africans carry the highest diversity and ancestral clades of all these haplo-groups. SMH. Asses.
Let me read what Sage has to say.

After the dispersal of modern humans Out of Africa, around 50–70 ky cal BP1,2,3,4 or earlier based on fossil evidence5, hominins with similar morphology to present-day humans appeared in the Western Eurasian fossil record around 45–40 ky cal BP, initiating the demographic transition from ancient human occupation [Neandertals] to modern human [Homo sapiens] expansion on to the continent1"

The haplogroup of PM1 falls within the U clade [Fig. 1B and Supplementary Table 3], which derived from the macro-haplogroup N possibly connected to the Out of Africa migration around 60–70 ky cal BP1,2,3,4. In line with this, the Peştera cu Oase individual that lived on the current territory of Romania, albeit slightly earlier than PM1 [37–42 ky cal BP] also displays haplogroup N9.

That's what I heard to and yet some in this thread are acting like I'm smoking crack. There was a recent study that claims U6 migrated from the Levant.
Heck U6 even in very low frequencies is found in the Levant if I remember correctly.

If you look at Pestera cu Oase also from Romania on this chart and older than PM1 (Pestera Muieri ) that is haplogroup N. That is ancestral to mtDNA R and R is ancestor to U.
U1 and U5 are older on this chart than U6
If you look at Pestera Muieri that was a woman also found in Romania who carried basal U6*
That haplogroup was formed before it split into U6a U6b and U6c.
This particular woman was not an ancestor herself to other individuals of these U6 splits but she carried the older basal U6* lineage type.
So her age, 35K is not the age of the basal U6* (50k) she carried
Although the exact origin dates are estimates. But so far that Romanian specimen is the oldest human remains found bearing U6

Sometimes it's better to revisit and reread your notes than to speak off the top from what you remember. Above I was arguing that U6 originated somewhere in Central Asia, and that UP European U6* and African U6abcd are two subclades separating from a Central Asian U6 carrying parent population that was on its way to West Eurasia. This is a wrongly remembered version of my original thoughts on U6. In my original notes this is what I had in mind.
U6 is analogous to R-V88, in that the both derive from (Central) Asian parents (mtDNA U and Y-DNA R), but also in that both were originally thought to be African, but have now turned out to have older offshoots in West Eurasia than in Africa. The older West Eurasian offshoots make sense because West Eurasia lies in between Central Asia and Africa.
The credible and latest estimates assign U6 a date of ~37ky old. If this is accurate (a big IF), then the Levantine Aurignacian comes into focus as an archaeological correlate of U6. And if the Levantine Aurignacian really is associated with U6, then U6 must have originated fully inside the Levant as Elite Diasporan was saying (not in Central Asia as I was alluding to above). The Levantine Aurignacian starts exactly around the time the latest research suggests U6 originated. See table 1, fig 2 and fig 3:
A couple of implications of this scenario that U6 itself (not just a U6 subclade) was spread by the Levantine Aurignacian people:
--In this scenario U6abd and some stage of pre-U6c represent the entry into Africa as two already differentiated branches, not as a single U6abcd clade as I was suggesting earlier --Since U6abd is 32ky old according Behar et al., the entry into Africa by U6abd and pre-U6c must have taken place around that time. They could have been attracted by the 33ky old wet spell in North Africa. By 32kya the Levantine Aurignacian had changed or declined (depending on how one interprets the archaeological record), which could indicate a partial displacement of Levantine Aurignacian population. This fits the 32ky old backmigration date well --This relatively late entry into Africa explains why UP European U6* is basal compared to U6abd and U6c --In this scenario mtDNA U was the Central Asian parent population, not U6 as I was arguing earlier --In this scenario UP European U6* migrated from the Levant, not directly from the aforementioned Central Asian parent population
I may end up being wrong in my reading, but this is more accurate representation of my original thoughts on Asia, the Levantine Aurignacian and U6.

My point? Don't just throw things out there without a reference of sort. That is like trolling. If you are not sure and can't back it up keep it to yourself ..until you can.

Yeah, you don't own this forum. Sam does. And I already posted one of the studies that state U^ could have come from the Middle East. Many past studies/authors have strongly hinted at U6 coming from the Middle East. Swenet even mentions the Levantine Aurignacian people. And I also mentioned that U6 is still found in parts of the Near East but in small frequencies. And no it is NOT like trolling.
Back on topic?

I would, but he's already been baiting in this thread multiple times already. Why are you defending yourself against trolling by someone who just finished making multiple (and consecutive) posts flame baiting (calling other people here retarded, etc)? You think he really cares about keeping this thread troll free? He's not going to stop. He'll just find a new way to bait later. If you want him to stop, make him. Don't ask him to get back on topic, finally tell him you'll do something. This has been the second (or fourth time if going by posts?) he's been on his messy diva bait shit.Make him stop it so we can get back to the topic, please.

Ah, but what is the age of U6 in the Arabian Plate?
Is AP U6 from pre-history or from the Amazigh girls whom one physician ranked the most perfect slave?
"The Berber women are from the island of Barbara (sic), which is between the west and the south. Their color is mostly black, though some pale ones can be found among them. If you can find one whose mother is of Kutama, whose father is of Sanhaja, and whose origin is Masmuda, then you will find her naturally inclined to obedience and loyalty in all matters, active in service, suited both to motherhood and to pleasure, for they are the most solicitous in caring for their children. Abu Uthman the slave-dealer says, If it happens that a Berber girl with her racial excellence is imported at the age of nine, spends three years in Medina and three years in Mecca, comes to Iraq at the age of fifteen and is educated in Iraq, and is bought at the age of twenty-five, then she adds to the excellence of her race the roguishness of the Medinans, the languor of the Meccans, and the culture of the women of Iraq. Then she is worthy to be hidden in the eyelid and placed in the eye."
~ ibn Butlān, a Nestorian Christian physician of Baghdad ~
Here is a quote.. Hervella et al "The U6 haplogroup is the only sub-haplogroup within the U clade currently present in Africa,.."
"the haplotype of the PM1 individual belongs to the basal U6 haplogroup from which the rest of haplotypes were derived (Fig. 2A). This scenario confirms that the U6 mitochondrial lineage has a Eurasian origin, supporting the hypothesis of an early back-migration from Eurasia to North Africa in the EUP"
"We found a basal U6 in South East Europe, on the current territory of Romania 35 ky BP, suggesting that either the U6 lineage originated in Eastern Europe or the TMRCA of U6 is older than 35 ky. "...(within an African origin-xyyman)
"Given the presence of a basal U6 mitogenome in Romania 35 ky BP, the distance between Western Asia and Romania, and the estimated diffusion pace of hunter-gatherer populations 30 suggest that the early populations carrying haplogroup U6 most likely started their spread*** to*** Eastern Europe before 40 ky BP."
"It is unclear whether the haplogroup U6 diversified in Africa or arrived to the continent as an already diversified lineage."

Lets just say we need more aDNA. The problem right now is the current models of the ancient origins of certain DNA lineages are based primarily on remains and DNA samples from said remains which are primarily from Eurasia and far older than any remains that have been sampled in Africa.
Until we get samples from African remains in North Africa, the Nile valley and so forth between 30 and 50 KYA we will never know for certain that migrating Africans were not the basis of these lineages.
This is the only thing I see here. Not necessarily a conspiracy but a model that is based on a lot of speculation, assumptions, missing data and hypothetical models.

I don't lnow about the Arabian plate but think more towards the Levant. Maybe 40-30k years. The one found in Romania imo could be of a early split which is why(someone correct) its different from the ones found in the Maghreb.
And the quote you posted I use to post a lot. European female slaves and European Muslim converts slowly started overtaking the indignous North African population due to the Maghreb as a whole being sparsely populated. Which is why they state some pale ones can be found among them. The Masmuda who imo were the main Berber groups who entered Southern Europe and were the main infantry.

He's not doing anything so far that is breaking the rules. But I did edit out some of his posts.
If I started suspending/banning people that annoy me then half of this forum would be suspended/banned.

Been busy but I'm back. All the arguments by the ignoramuses in this forum aside, this comment by Beyoku below is also the conclusion I got from the study.
quote:Originally posted by beyoku: I have been reading over the data and.....................I dont think Taforalt are "Mixed" in the same way people are thinking they are "partly Natufian partly African".
All the commentary i see outside of ES simply has it wrong. We are going to need MORE ancient DNA to really know what we are looking at. They are all still making the same mistake of not accounting for African substructure. They aint learned shit. In all commentary have seen about the study the word "Substructure" is MIA. Its also not in the article.
Taforlat are not partly Naufian/Hadza/Mende because Dinka are NOT 90% Yoruba. Somali are not a combination of Yoruba and Natufian. Mota do not have more North African ancestry than Mozibites and Saharawi.
Beyoku is absolutely correct. I have read other population genetic studies especially in regards to Asia or Eurasia as a whole they all speak of substructure yet when it comes to African populations this fundamental element is missing despite Africa being the source of all human genetis diversity. This is why people use modern SSA as a strawman for all African when we here in Egyptsearch know that there was more elements to indigenous African populations. Even Swenet makes an excellent argument as to why 'Basal Eurasian' is actually African in origin. This is why when it comes to genetic population structure especially of prehistoric populations I tend to take the interpretations with few grains of salt until as Beyoku says we get more genetic data.

Why is someone outside a clique expressing an opinion/interpretation that differs from yours an ignoramus?
