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]
The Nordic race is an obsolete racial classification of humans based on a now-disproven theory of ... as an "ethnic group" ... its pure blue or grey eyes". [33] [32]
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.
[62] [63] Athena is described as having blondish or brownish hair (xanthe (Ξανθή)) [64] and blue, green, or grey eyes. [ 65 ] [ 66 ] Contrarily male warriors like Odysseus were usually described as having brown or bronzed skin, unless attention was being brought to skin that was vulnerable to injury in battle.
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 ] )
The representation of ethnic groups in Egyptian iconography has been a source of dispute among scholars. [3] [4] The question of the race of the ancient Egyptians was raised historically as a product of the early racial concepts of the 18th and 19th centuries, and was linked to models of racial hierarchy primarily based on craniometry and ...
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 and ethnic demographics of the United States in percentage of the population. The United States census enumerated Whites and Blacks since 1790, Asians and Native Americans since 1860 (though all Native Americans in the U.S. were not enumerated until 1890), "some other race" since 1950, and "two or more races" since 2000.
