quote:genetic diversity in Eurasians is largely a subset of that in Africans, supporting the out of Africa model of human evolution
Not true. Africans have highest (mean) genetic and craniometric variation because they had the largest population size throughout the entire Pleistocene. Population size mimics a recent African origin. See:
Relethford, J.H. and Harpending H.C. 1995. Ancient differences in population size can mimic a recent African origin of modern humans. Curr. Anthropol. 36:667- 674
No geneticist now uses this as evidence for RAO (recent African origin).

"Genetic diversity is greater in African farming people than in African hunters-foragers."(Watson et al., 1996)
Mean genetic variation is simply down to population size. More people = more mutations, less drift.

Lame, very lame. Mod is deleting Swenet's replies?
This forum is virtually dead, now with malware all over it, and you delete the only sensible or knowledge posters replies. Come 2015 there probably wont be a single person on here, so just leave his stuff up.

All posts which are not respectful to the person whose point is being countered will be deleted. Since ARtU asked not to be personally defamed and Swenet continued ad hominem his post was deleted.
In either case ES EGYPTOLOGY (even should it disappear in a day) doesn't need him or you.
We'd like to have you both but whoever refuses to behave as in adult company will find themselves on the outside looking in should a mature member object to character assasination and make it known to me.
If one wishes to post, one must abide by forum policies designed to make this forum an inviting place for lurkers to turn into posters without cringing at the thought of immature responses.

No matter how many times you try to repost you will be deleted. You can't force yourself on the forum.
So post away. As long as you fume ad hominem your effort is a waste. I will delete your disrespectful missives when I get around to it. so go ahead knock yourself out if you've nothing better or productive to do.
You will not come here and **** on the ES people that you hate so much It will not be tolerated.

As for the imminent death of this forum plans were put in place since 2005 for interested parties to continue as a group via TheNileValley forum and EgyptSearchReloaded should EgyptSearch parent site fall.

I just explained xyymans error and brada comes in an does the same thing
There is no such thing as a " stereotypical Eurasian" Eurasia is the whole landmass of Europe and Asia, one continuous piece of land with a wide variety of people on it.
Brada does the same thing, he starts off about Eurasia then in the same sentence says there were no whites in Europe 40 kya -as if the to terms are synonymous
People please stop this "Europe" does not even comprise most of the landmass of Eurasia
The origin of HG R is believed to be Eurasia but not in Europe,
Not necessarily in Siberia, However the oldest remains of R was found there 24Kya (Raghavan 2014) the Mal'ta boy (mtDNA U)
Sure,
quote: Table S1. Haplogroup Affiliation of the Seven Chromosomes that Were Re-sequenced
The number of deep branchings leading to African-specific clades has doubled, further strengthening the MSY-based evidence for a modern human origin in the African continent. An analysis of 2204 African DNA samples showed that the deepest clades of the revised MSY phylogeny are currently found in central and northwest Africa, opening new perspectives on early human presence in the continent.
[...]
conclusion, we present here a Y chromosome phylogenetic tree deeply revised in its root and earliest branches. Our data do not uphold previous models of Y chromosomal emergence15 and 16 and demand a reevaluation of some fundamental ideas concerning the early history of the human genetic diversity we find today.38, 39 and 40 Our phylogeny shows a root in central-northwest Africa. Although this point requires further attention, we think that it offers a new prospect from which to view the initial development of our species in Africa.
The deepest branching separates A1b from a monophyletic clade whose members (1a A2, A3, B, C, and R) all share seven mutually reinforcing derived mutations (five transitions and two transversions, all at non-CpG sites).
quote:Originally posted by Clyde Winters: This innocent looking article, without any support for its conclusions is very dangerous and should be vigorously attacked. Its aim is to resurrect the multiregional theory for the raise of anatomically modern man--with Eurasia--as the center for this evolution.
In this article the authors claim that diversity among African genes is the result of Eurasian genes. They contend that the Eurasian genes exist in Africa because of a back migration.
On the surface this seems like a pretty tame theory. In reality this is quite radical. What the authors are saying is, sure Africans are diverse, but this diversity is the result of Eurasians migrating back into Africa.
If you accept this hypothesis, the next step is to claim that the diversity among haplogroups took place in Eurasia, rather than Africa, and that Europe--not Africa--is the center of evolution and genomic diversity. This is just a first step in destroying the out of Africa (OoA) theory and replace it with a multiregional theory that moves Eurasia back into the center for the raise of modern man.
This paper is a call to return to the days of white/European supremacy in world events and history.

Cosigned. Especially because these authors stated that they will continue these works.

^^That's not what is says. It's says African people are genetically close to each others (low fst). And that Northeastern Africans (Amhara, Somali and a bit surprisingly Oromo) have substantial level of Eurasian admixtures which create genetic distance between East and other Africans.
The fact that Northeastern Africans like Amhara have a substantial level of Eurasian admixtures is a big duh. We all know it from multiple research posted on this very site. A lot of those Northeastern African populations even speak a Semitic (ethio-semitic) languages. If you deny it you have no place in the egyptology forum which is about science.
The study dates the earliest substantial admixtures in Northeastern Africa to be around 3200 years ago which equal (3200-2014=)1186BC. That date roughly correspond to the beginning of the foreign conquests of Ancient Egypt in the late period. Although in my opinion they must have been low level of genetic admixtures well before that time at least in Ancient Egypt which are even closer to Eurasia.
All humans nowadays are admixed to each others at various degrees, from low to high. The level of admixtures in other Africans beside Northeastern Africans is low but existent. Which is very true and is vice versa as Eurasian also have various level of African admixtures especially West Asians and Europeans (in that order). When we talk about African admixtures we talk about admixtures with people who stayed back in Africa (and eventually migrated within it) during the OOA migration.
So this study is perfectly fine, it uses Whole Genome Sequence.
The results are very balanced and not ideologically driven like Clyde and Troll here. The study involved the participation of a various African institutions.
This is the proportion of Eurasian admixtures in various African populations. Eurasian people are people who left Africa during the OOA migrations.
^^^We can see above that the level of Eurasian admixtures in most of African populations is very low (from 0 to low %) but still present. It is higher in Northeastern Africa which borders Eurasia. From other studies we know Eurasians also have various level of admixtures with Africans.

@ the so called hardcore "Afrocentric" above.
We, read sources on how Eurocentrics interprete this. They clearly state, that whites/ Europeans intruded deep into Africa.
quote:Originally posted by xyyman: To the brotha in the bad mood
Added to that, I just came across a paper on the Vikings. Dienekes sourced it within the last few days. The paper is suggesting there was another significant population turnover between 1500-1000AD in Europe, at least Northern Europe. Around the Viking age. aDNA was tested on Vikings and to their surprise about 25% of the mtDNA haplotypes were NOT found in Europe. And the MFers stopped there. They left it at that. Not disclosing where in the world 25% of the Vikings matched up. Nevertheless from what was disclosed many of the Vikings were J1b. Lioness what did Eupedia say about mtDNA J1b? That’s right…..Some African Tribes still carry mtDNA J1b.
I GOT THIS COVERED.
quote:The IJ haplogroup characterizes part of the second wave of emigration from Africa that occurred via the Middle East 45,000 years bp and defines two branches I and J that emigrated northwards and eastwards into Europe. The J branch subsequently split again and contributed to the current North African population.
This chart can be highly misleading. The idea of extensive Eurasian admixture in countries usch as Ethiopia is easily explained by the closeness of the territory. The Oromo-Eurasian admixture frequency is quite interesting. Sure, it is high but Col. Rawlinson used Oromo to decipher the Sumerian language. This is interesting because it puts Oromo speakers in Mesopotamia long before the coming of the Indo-Europeans and Turks. The so-called Eurasian elements may simply be remnants of the genome taken to Eurasian by African populations like the Oromo.

For one, I'm not an afrocentric. Secondly nowadays every human populations are admixed with each others at various degree so it's not a problem. I don't to ignore or reject scientific data. As a black man I just take the control of the narrative instead of leaving it to others. I analyse scientific data and provide a factual narrative that is relevant to us black people. Everybody should do the same for themselves.
