Canarian Genetic Study

[Isleño]

Canarians are commonly perceived to be predominantly European with minor North African ancestry, some more, some less. But is this true? Let's take a closer look at Canarian genetics in comparison to Iberian genetics and North African genetics. This look into Canarian genetics is based on the study from Pino-Yanes et al., 2011.

Since it's anticipated that Canarians are predominantly European, this thread will examine the North African admixture percentage in Canarians.

Looking at the samples from the study this thread is based on, I counted the number of samples that made up the Canarian sample as a whole. I also counted the number of samples with no North African ancestry, those that are around half to mainly North African ancestry and those with minor North African admixture whom are predominantly European. From what I can tell (I'm rounding the percentage), it looks like about 50% of the samples are mainly European with minor North African admixture, about 30% have no North African admixture and look to be completely European or near full with just a few percent, and about 20% are around half to mainly North African. {50%/30%/20%} Again, this look into Canarian genetics is based on the study from Pino-Yanes et al., 2011.

Calculated North African total averages among Canarians as a whole and per island, in comparison to Iberians and North Africans




My conclusion of the study is that half of the population of the Canary Islands is predominantly European with minor admixture. Almost One-third of the population is completely European or having around 1-5% admixture and one-fifth is at least half or mostly North African. So it does hold true that most Canarians are predominantly European with minor North African admixture. But surprisingly, a significant portion of the population is purely European and a smaller population is at least half to predominantly North African.

To break it down even further, we can say that 50% are predominantly Euro with minor NA admix (10-20%), 30% are a mix of full and near full Euros (1-5% NA admix), 10% are mestizo types (half Euro/half Berber) and 10% are predominantly Guanche Berber. Of course these numbers have been rounded off. {50/30/10/10}

I fall into the largest group, whom are those of predominantly European ancestry with minor North African admixture as my genetic make-up is 90% European, 10% North African.

That's cool.
But why Is there Spanish and Iberian separated ?

Spaniards are Iberians.

Spaniards are Iberians.

I wondered the same thing. There has to be a particular reason they did this. Maybe the "Iberian" was a sample including both Spanish and Portuguese where the Spanish sample included only Spaniards.

It's seems of low quality that "Study".
Or they make one as Portuguese and Spaniards.
Or Iberians as a hole.Me think's.

No, it's a good study, it's very accurate and is in line with other studies I've seen on Canarians. But as far as the thing with that Iberian/Spaniard on the plot, the only thing I could guess is that the "Iberian" sample includes Portuguese where the "Spaniard" sample only included Spaniards. I'm almost sure that's what it means.

The Guanches weren't Berbers after all?

Yes they were Berbers, but I also have a hunch that they were a mix of Proto Berber Capsian types and Iberomaurusian descended types.

I know a few Guanches were taken to Iberia and the Americas also.

What I think will be quite a surprise for many, is that 1/3 of the population is purely European and has no Guanche ancestry. The other 2/3 does.
