That's what I thought at first. The interesting thing about the article is that it shows the native population was already pretty diverse by the time of first contact with the Europeans. Also, a minor nit picking. Even if slaves brought to Mexico came from a very specific Portuguese enclaves within the African continent, the population within Africa is extremely diverse. It would not surprise me if they brought about as much diversity as the other two source "races", for lack of a better word. It seems a bit too simple to have them reduced to a note margin as in "imported Africans".
