Genetic Consequences of the Transatlantic Slave Trade in the Americas
According to historical records of transatlantic slavery, traders forcibly deported an estimated 12.5 million people from ports along the Atlantic coastline of Africa between the 16th and 19th centuries, with global impacts reaching to the present day, more than a century and a half after slavery’s abolition. Such records have fueled a broad understanding of the forced migration from Africa to the Americas yet remain underexplored in concert with genetic data. Here, we analyzed genotype array data from 50,281 research participants, which—combined with historical shipping documents—illustrate that the current genetic landscape of the Americas is largely concordant with expectations derived from documentation of slave voyages. For instance, genetic connections between people in slave trading regions of Africa and disembarkation regions of the Americas generally mirror the proportion of individuals forcibly moved between those regions.
While some discordances can be explained by additional records of deportations within the Americas, other discordances yield insights into variable survival rates and timing of arrival of enslaved people from specific regions of Africa. Furthermore, the greater contribution of African women to the gene pool compared to African men varies across the Americas, consistent with literature documenting regional differences in slavery practices. This investigation of the transatlantic slave trade, which is broad in scope in terms of both datasets and analyses, establishes genetic links between individuals in the Americas and populations across Atlantic Africa, yielding a more comprehensive understanding of the African roots of peoples of the Americas.
Space added by me to ease reading.
Jimmy the Greek write that?
Thank you for your cogent analysis.
It might be likely, too, that genetics could prove the Irish came to Boston after the Brits starved them, too.
WTF is your point, Josh?
For an equivalence, that study would need to look at the different sections of Ireland that they came from and to look far more broadly than Boston. And it would be an interesting study to read,
to some of us. Further, it would follow on the heels of prior studies that focused solely on County Cork, while ignoring the larger population centered in Counties Clare and Kerry.
"My" point is that "this investigation of the transatlantic slave trade ... establishes genetic links between individuals in the Americas and populations across Atlantic Africa, yielding a more comprehensive understanding of the African roots of peoples of the Americas." It has a bunch of other features, beyond the general conclusion, as well.
I suspect(ed_ that
some of the people here would be interested in such a thing. Your disinterest is duly noted and I won't tag it for your attention next time.
