Race (biology) Four different ecotypes, i.e. ecological races, of the species Physcomitrella patens, stored at the International Moss Stock Center. In biological taxonomy, race is an informal rank in the taxonomic hierarchy for which various definitions exist. Sometimes it is used to denote a level below that of subspecies, while at other times ...
e. 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]
v. t. e. Scientific racism, sometimes termed biological racism, is the pseudoscientific belief that the human species is divided into biologically distinct taxa called "races", [1][2][3] and that empirical evidence exists to support or justify racial discrimination, racial inferiority, or racial superiority. [4][5][6][7] Before the mid-20th ...
ISBN 978-0-309-70065-8. PMID 36989389. In humans, race is a socially constructed designation, a misleading and harmful surrogate for population genetic differences, and has a long history of being incorrectly identified as the major genetic reason for phenotypic differences between groups.
Human taxonomy. is the classification of the human species (systematic name Homo sapiens, Latin: "wise man") within zoological taxonomy. The systematic genus, Homo, is designed to include both anatomically modern humans and extinct varieties of archaic humans. Current humans have been designated as subspecies Homo sapiens sapiens ...
Mozambique tilapias often travel in groups where a strict dominance hierarchy is maintained. Positions within the hierarchy correlate with territoriality, courtship rate, nest size, aggression, and hormone production. [36] In terms of social structure, Mozambique tilapias engage in a system known as lek-breeding, where males establish ...
The category includes people who are of full or partial Hispanic or Latino origin. They typically have origins in the Spanish-speaking nations of Latin America, although a few also come from other places (0.2% of Hispanic and Latino Americans were born in Asia, for example). [123] The group is heterogeneous in race and national ancestry.
Human genetic variation is the genetic differences in and among populations. There may be multiple variants of any given gene in the human population (alleles), a situation called polymorphism. No two humans are genetically identical. Even monozygotic twins (who develop from one zygote) have infrequent genetic differences due to mutations ...
