Categorization of racial groups by reference to skin color is common in classical antiquity. [7] For example, it is found in e.g. Physiognomica, a Greek treatise dated to c. 300 BC. The transmission of the "color terminology" for race from antiquity to early anthropology in 17th century Europe took place via rabbinical literature.
The Nordic race is an obsolete racial classification of humans based on a now-disproven ... (meaning 'northern') as an "ethnic group" ... its pure blue or grey eyes ...
The total number of genes that contribute to eye color is unknown, but there are a few likely candidates. A study in Rotterdam (2009) found that it was possible to predict eye color with more than 90% accuracy for brown and blue using just six SNPs. [16] [17] In humans, eye color is a highly sexually dimorphic trait. [18]
Early racial classification attempts measured surface traits, particularly skin color, hair color and texture, eye color, and head size and shape. (Measurements of the latter through craniometry were repeatedly discredited in the late 19th and mid-20th centuries due to a lack of correlation of phenotypic traits with racial categorization. [ 42 ] )
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]
Racial identity was not governed by a rigid descent rule. A Brazilian child was never automatically identified with the racial type of one or both parents, nor were there only two categories to choose from. Over a dozen racial categories are recognized in conformity with the combinations of hair color, hair texture, eye color, and skin color.
In the late 18th century, German anthropologist Johann Blumenbach extended Linnaeus's four-color race model by adding the brown race, "Malay race", which included both the Malay division of Austronesian (Southern-Thailand, Cambodia, Indonesia, Philippines, Malaysia, Brunei, Pattani, Sumatra, Madagascar, Formosans, etc.) and Polynesians and ...
The Interagency Committee agreed, stating that "race" and "ethnicity" were not sufficiently defined and "that many respondents conceptualize 'race' and 'ethnicity' as one and the same underscor[ing] the need to consolidate these terms into one category, using a term that is more meaningful to the American people." [5] The AAA also stated:
