Abstract The aim of this study was to establish the genetic studies of the population from one of the most important known aboriginal funerary spaces of the island of El Hierro (Canary Islands), the Punta Azul cave, which harbors remains of 127 individuals. Sixty-one adult tibiae were examined, 32 left and 29 right. Radiocarbon dating yields an antiquity of 1015–1210 AD. We have obtained an overall success rate of 88.5% for the molecular sexing, and of 90.16% for the uniparental markers. Short tandem repeats (STR) profiles were also possible for 45.9% of the samples. This performance is a consequence of the good conservation of the bones in their archaeological context. The mtDNA composition of the sample is characterized by the complete fixation of the H1-16260 lineage. These results can be explained by a mixture of consecutive founding events, a bottleneck episode at the beginning of the colonization and/or as a consequence of genetic drift. Paternal lineages were also affected by these processes but in a less acute way. These differences lead us to propose social behaviors as an explanation for this difference. The maternal transmission of the lineages, mentioned in ethnohistorical sources of the Archipelago, could be an explanation. These results could be in agreement with endogamous practices, but the autosomal STR results indicate a relative high diversity. These results have allowed us to characterize the Punta Azul cave population and see the way in which geographical isolation, the process of adaptation and specific social behaviors affected the aboriginal population of the Island.

So, more evidence that DEBUNKS the Steppes Hypothesis. R1b-M269 was present in Africa BEFORE the arrival of "Europeans". Also more evidence of the continuum. The ancient Natives carried as much as 50% "European" lineage from the Steppes(insert Sarcasm). Lol! The other lineage was South Saharan and indigenous North Saharan. Apparently it was a matrilineal society like a lot of Africans. I wonder how those "white" males made out amongst these Africans? Did they fear for their life(Insert sarcasm). These ancient Africans also carried mtDNA H1 UNIQUE to Africa(North). So much for back-migration (lol!).
Why do we even continue these discussions and absurd beliefs?

Lol. I swear yesterday I said to myself gramps is going to claim M269 now based on this paper. And sure enough..

Why not just read it in context? They have Y-DNA I, which is indisputable evidence of contact (whether direct or indirect) with Iberians. Stop the spin gramps

Yes "young boi".

Point!! There was NEVER any isolation it was always a continuum. ALL recent papers have proven that. There is no race! There is no "admixture" , the proper label is SHARING. Sharing of SNPs or AIM. Isolation by Distance with increasing frequency emanating from ....YES.....AFRICA! Europeans are a subset of Africans...both old and new. It is only within the last 400years modern Europeans(the subset) has gain control over the world.
"Sure enough" test these ancient Africans(precolonial) and my money is they carry an OLDER version of Western European (R1b-M269). But they wouldn't. you know why? Tic! Tic! Tic!
This is not rocket science.

Do you know why I am ALWAYS right and I got this?
Answer: I am not prejudiced by modern politics and modern European influence. The answers are staring them in the face.

I assume you have the Supplemental? In the main paper(which I downloaded) they Reported for 16males carrying E1a, R1b-M269 and E-M81 Table 2. But they typed 36 males. Are they with-holding data....yDNA -I ?

Ok gramps. I give up. Your overwhelming evidence debunked me..
Posted by xyyman (Member # 13597) on :
You don't get off that easily. WTF? yDNA-I where? when? what? lol! They reported only 16 haplogroups but said they typed 36 males. You know something I don't.?
share!

See the other report with 'aboriginal' Canary Island 'aDNA'. Also look at their mtDNAs. These sampled individuals might even be less African than modern day coastal Maghrebis.
Now he is "moonwalking". Lol! But you are too young to know what that is. "OTHER" report? Careful you are tripping over yourself. ..."young bwoi".
What is "less African"? Berbers are Africans!!
Even if I is present doesn’t that prove me correct ....again. "I" is also African. The belief is yDNA-I has a Sardinian origin. And it is absent in East Africa. Tic! Tic! Tic! Significance?
Quit while you are behind!
There was no "I" in the El Hierro. But the question remains. Why did they only report 16 out of 36 male haplogroups? Agreed they were warranted in focusing on R1b-M269 and the high frequency PRIOR to the arrival of "Europeans". That is significant. Proving "European" colonialism had very little genetic impact...on the male side. Although there was a decease in South Saharan lineage.

C'mon gramps. You were caught with your pants down making fictitious claims about Canary Island uniparentals talking 'bout "they're all H1" and "pure African".
Then you learn about the larger context of regional 'aDNA' and the first thing you do is scramble for half-baked explanations why Meslithic European mtDNAs and Y DNAs are there. You're caught with your pants down. Thumping your chest with your buttcheeks out doesn't make you right. It makes you look rediculous.

This is a teaching moment. Don't get caught up in modern geopolitics. There is no "European" genes. "Europe" is only 7 miles from Africa!!!!! Europeans are new to the world and recently added to the civilized world. Civilization started in Africa. Eurocentric beliefs is screwing up the world. They only dominated the world for the last 400years and the direction China, India, South America.... and Africa is heading. It will come to an end within the next 100years. And we will be back on track. Back to our civil way of doing things as it should be.
I can safely conclude now. Just like mtDNA-H . R-M269 is ALSO of African origin. I always speculated but waiting on more proof. This is further affirmation.

Yeah! Yeah! Make shyte up now. SMH
