Scientists from the consumer genetics company 23andMe<\/a> have published the largest DNA study<\/a> to date of people with African ancestry in the Americas<\/a>.<\/em><\/p>\n

More than one and a half centuries after the trans-Atlantic slave trade<\/a> ended, a new study shows how the brutal treatment of enslaved people has shaped the DNA<\/a> of their descendants.<\/p>\n

The report<\/a>, which included more than 50,000 people, 30,000 of them with African ancestry, agrees with the historical record about where people were taken from in Africa<\/a>, and where they were enslaved in the Americas<\/a>. But it also found some surprises.<\/p>\n

For example, the DNA of participants from the United States<\/a> showed a significant amount of Nigerian ancestry \u2014 an unexpected finding, as the historical record does not show evidence of enslaved people taken directly to the United States from Nigeria<\/a>.<\/p>\n

At first, historians working with the researchers \u201ccouldn\u2019t believe the amount of Nigerian ancestry in the U.S.<\/a>,\u201d said Steven Micheletti<\/a>, a population geneticist at 23andMe who led the study…<\/p>\n

…The 23andMe project found this general pattern, but also uncovered a startling difference in the experience of men and women between regions in the Americas.<\/p>\n

The scientists calculated that enslaved women in the United States contributed 1.5 times more to the modern-day gene pool of people of African descent than enslaved men. In the Latin Caribbean, they contributed 13 times more. In Northern South America<\/a>, they contributed 17 times more.<\/p>\n

What\u2019s more, in the United States, European men contributed three times more to the modern-day gene pool of people of African descent than European women did. In the British Caribbean<\/a>, they contributed 25 times more…<\/p>\n
