On the other hand, Fogo and Brava became more Portuguese early on, both in terms of demographics, culture, and admixture.

As to your latter point, the trade between these islands also involved people. I know at least between Madeira and Cape Verde, there were population movements in both directions.
There was some movement but very limited between the Azores and Cape Verde mostly the purchase of slaves from Cape Verde it is well recorded that slaves were imported to the Azores from the Cape Verdean island of Santo Antao in 1548. The movement between Madeira and Azores was pretty much in one direction settlers from Madeira to the Azores.

I contacted my matches with sub-Saharan African maternal lineages they both responded to my questions both of their maternal lineages trace to my island of origin in the Azores. FTDNA at some point updated the match list and some people that previously showed as matches dropped off.

1. Hoplogroup L2a1c uncommon in West Africa her only match with Africa is from Mali at the HVR1 level meaning the common maternal ancestor has a 50% chance of being within the last 1,500 years. It is also possible her match has only tested at the HVR1 level. I match 36CM of autosomal DNA with this match.

Someone created an interesting video on the distribution of mtDNA L2a1c in Africa

2. Haplogroup L0a1 she has matches with individuals whose origins are from African countries. I match 197CM of autosomal DNA with this person.

West Africa
Guinea-Bissau 2(1) from the Beafada tribe which is estimated between 45,000-55,000 members.

Ghana 1 from the Fante tribe

The following matches are either found along the Sahel trade route or near which runs across Africa from Senegal to Eritrea just south of the Saharan desert.
https://en.wikipedia.org/wiki/Sahel

Ethiopia 4, Sudan 1, Chad 1,

These matches are found in Southern Africa

South Africa 1, Zimbabwe 1.

I bolded the match which indicates the region I think most plausible based on the known trade between the Azores, Cape Verde and Guinea-Bissau.

I found a link that discusses the slave population on the island of Terceira in the Azores mid 1550's the records indicate that 51.55% were classified as Black, 11.34% as Moriscos(Moroccan Berbers), and 35% Mulatto believed to be a mix of Black, Morisco and a significant input from White men.

The paper is in Portuguese I don't know if you can read the language I apologize there are no English language sources for this type of information, it also states that most of the black Africans were from Guinea but some were also from the island of Sao Tome.

I should have stated that #2 also has matches at the HVR1 level in various European countries, native Europeans not African immigrants which I found interesting.

UK 2
Denmark 1
Italy 10(2) Sicily
Spain 2
Portugal 2(2) Azores

The "100%" refers to ancestry, doesn't it? ...as in 100% of your ancestors at a certain time in the past likely lived in Europe, or Africa, or Japan...

People like to point out that all humans share >99% of our DNA, as if that proves we are really all the same, forgetting that we also share >98% with orangutans.

In fact it's probably a lot less considering the DNA tested and reported on are only the markers we know and identify... Not to suggest that it's more useful to think of 100% in the context of just the different DNA, but with all the talks of percentage of inherited DNA etc it's important to remember this context.

Thank you for sharing those links -- very informative! I definitely think the African ancestry in Azores and Madeira is mostly shared with Cape Verde.

Have you tried the website DNA.Land?

No I have never heard of them sounds really interesting are you participating?

Yep. Even critters like spiders and praying mantises have 70-ish% of our DNA, and they're not even mammals. That DNA chain is looooong. More importantly it is highly redundant. What makes us unique are the incredibly subtle nuances.

To say that an Italian and an Irishman are genetically similar seems absurd to me. Sure they're probably 99.98% the same, but it's that 0.02% that truly matters.

So if a Celt and a Lombard are genetically distinct, how much more so are, say, a Pole and a Laotian? A Finn and a Somali? A Korean and a Guarani?

Actually the 100% doesn't quite refer to what you mention. Since autosomal DNA is inherited randomly it will not represent an even picture of your ancestry. Some DNA from certain ancestors beyond about 5 generations will not be represented at all.

The 100% is the very small percentage of autosomal DNA that you have that can in fact be different between people and inside of that they are the markers that research has identified as likely representative of a certain ethnic regional group.

The fact that we share so much with orangutans is not surprising at all, they are a very close evolutionary sibling. Though you are correct in that we share much DNA with most life on this planet (not surprising since we all evolved here together). The thing to remember is DNA is *huge*... it's 2.9 billion base pairs. 1% of that is still 20 million base pairs.

Are these results from ancestry.com? My results from FTDNA show 0% sub-Saharan African they surpress percentages less than 1%, FTDNA also surpesses the Ashkenazi diaspora for percentages less than 2%.

Have you downloaded your raw data to Gedmatch.com? Those calculators can pick up minor admixture.
