Researchers have investigated the relationship between race and genetics as part of efforts to understand how biology may or may not contribute to human racial categorization. Today, the consensus among scientists is that race is a social construct, and that using it as a proxy for genetic differences among populations is misleading. [1] [2]
Race: The Power of an Illusion is a three-part documentary series produced by California Newsreel that investigates the idea of race in society, science and history.

Skepticism towards the validity of scientific racism grew during the interwar period, [10] and by the end of World War II, scientific racism in theory and action was formally denounced, especially in UNESCO's early antiracist statement, "The Race Question" (1950): "The biological fact of race and the myth of 'race' should be distinguished.

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]
This rigid definition of race is no longer accepted by scientific communities. [ 1 ] [ 2 ] Instead, the concept of 'race' is viewed as a social construct . [ 3 ] This means, in simple terms, that it is a human invention and not a biological fact.
Human taxonomy is the classification of the human species within zoological taxonomy. The systematic genus, Homo, is designed to include both anatomically modern humans and extinct varieties of archaic humans.
