All modern humans share the same origin from this single ancestral population. Modern polygenists do not accept either theological or scientific monogenism. They believe that the variation among human racial types cannot be accounted for by monogenism or by evolutionary processes occurring since the proposed recent African origin of modern humans .
1 percent of African Americans have at least 50% European ancestry (equivalent of one parent) (Gates is one of these, he discovered, having a total of 51% European ancestry among various distant ancestors); and; 5 percent of African Americans have at least 12.5% Native American ancestry (equivalent to one great-grandparent).

Correspondence between genetic clusters in a population (such as the current US population) and self-identified race or ethnic groups does not mean that such a cluster (or group) corresponds to only one ethnic group. African Americans have an estimated 20–25-percent European genetic admixture; Hispanics have European, Native American and ...
The word "race", interpreted to mean an identifiable group of people who share a common descent, was introduced into English in the 16th century from the Old French rasse (1512), from Italian razza: the Oxford English Dictionary cites the earliest example around the mid-16th century and defines its early meaning as a "group of people belonging to the same family and descended from a common ...
If a more consistent report with the genetic groups in the gradation of genetic mixing is to be considered (e.g. that would not cluster people with a balanced degree of African and non-African ancestry in the black group instead of the multiracial one, unlike elsewhere in Latin America where people of high quantity of African descent tend to ...
For example, fruit flies share 61 percent of disease-causing genes with humans, which was important when NASA studied the bugs to learn more about what space travel might do to your genes.
My great-great-great-great grandfather Hewlett Sands, born into slavery in Oyster Bay, New York in 1820, was one of the more than 200,000 names listed on the African American Civil War Memorial in ...
