Tang and colleagues (2004) wrote, "we detected only modest genetic differentiation between different current geographic locales within each race/ethnicity group. Thus, ancient geographic ancestry, which is highly correlated with self-identified race/ethnicity—as opposed to current residence—is the major determinant of genetic structure in ...
Race is a categorization of humans based on shared physical or social qualities into groups generally viewed as distinct within a given society. [1] The term came into common usage during the 16th century, when it was used to refer to groups of various kinds, including those characterized by close kinship relations. [2]
Social interpretations of race regard the common categorizations of people into different races. Race is often culturally understood to be rigid categories ( Black , White , Pasifika , Asian , etc) in which people can be classified based on biological markers or physical traits such as skin colour or facial features.
Transracial is a label used by people who identify as a different race than the one they were born into. They may adjust their appearance to make themselves look more like that race, and may participate in activities associated with that race.
It defines "white people" as "people having origins in any of the original peoples of Europe, the Middle East, or North Africa". [6] The Federal Bureau of Investigation uses the same definition. [7] The definition actually does vary and is also published as "a light skinned race", which avoids inclusion of any sort of nationality or ethnicity. [8]
Much of the color-based classification relates to groups that were politically significant at different points in US history (e.g., part of a wave of immigrants), and these categories do not have an obvious label for people from other groups, such as people from the Middle East or Central Asia. [1]
In it, Lewontin presented an analysis of genetic diversity amongst people from different conventionally-defined races. His main finding, that there is more genetic variation within these populations than between them, [2] is considered a landmark in the study of human genetic variation and contributed to the abandonment of race as a scientific ...
The number of ethnicity/nationality options available on Soviet censuses was enormous—the Soviet Union offered 194 different choices for ethnicity/nationality in its 1926 census. [74] There were 97 options in 1939, 126 options in 1959, 122 options in 1970, 123 options in 1979, and 128 options for the Soviet Union in 1989. [ 74 ]
