I'm not really sure but DNA is weird business. I have my own theory which is that there were Negroid-Native Americans (a long with Asiatic) already on this land when WP came. They were the first people to be enslaved and later African slaves were brought over and to some extent mixed together. As the geneticist in the video indicates, they over simplify our DNA while falsely diversifying the DNA of WP. So they lump similar "negro/African" DNA together. However, if they are basing these communities off the DNA of Africans on the continent ( ie why someone who is not AA would relate strongly to an AA community) then I would think that the more African, as opposed Negroid-American, ancestors you have the strong you will relate to these communities.
I believe I may have more Negro-Native DNA that you or less African DNA, although I believe you have it too, which is why I related lower to the communities.
This is a really good article from the department of interior that touches on the enslavement of natives and how they relate to AA.
NPS Ethnography: African American Heritage & Ethnography
" After the passage of this law many “black-Indians” found themselves classified as black and forced into slavery.
In the fields and homes of colonial plantations, mutually enslaved African Americans and American Indians forged their first intimate relations. In spite of a later tendency in the Southern colonies to differentiate the African slave from the Indian, chattel slavery was built on a preexisting system of Indian slavery.
Even though the arrival of Africans in 1619 began to change the face of slavery in North America from “tawny” Indian to “blackamoor” African, Indian slaves were exported throughout the Caribbean often in trade for Africans. As the 18th century dawned the slave trade in American Indians was so serious that it eclipsed the trade for furs and skins and had become the primary source of commerce between the English and the South Carolina colonials (Minges 2002:454).
...The 1740 slave codes of South Carolina served to blur the distinction between African, American Indian and the children of their intermarriage, declaring:
All negroes and Indians, (free Indians in amity with this government, and negroes, mulattoes, and mustezoses, who are now free, excepted) mullatoes and mustezoes who are now, or shall hereafter be in this province, and all their issue and offspring…shall be and they are hereby declared to be, and remain hereafter absolute slaves (Hurd 1862:303 as cited in Minges 2002:455)
