The informal taxonomic rank of race is variously considered equivalent or subordinate to the rank of subspecies, and the division of anatomically modern humans (H. sapiens) into subspecies is closely tied to the recognition of major racial groupings based on human genetic variation. A subspecies cannot be recognized independently: a species ...
It has been used as a higher rank than strain, with several strains making up one race. [ 2 ] [ 3 ] Races may be genetically distinct populations of individuals within the same species , [ 4 ] or they may be defined in other ways, e.g. geographically, or physiologically. [ 5 ]
Human behavioral ecology (HBE) or human evolutionary ecology applies the principles of evolutionary theory and optimization to the study of human behavioral and cultural diversity. HBE examines the adaptive design of traits , behaviors , and life histories of humans in an ecological context.
Genetic studies of traits and populations have been used to justify social inequalities associated with race, [7] despite the fact that patterns of human variation have been shown to be mostly clinal, [8] with human genetic code being approximately 99.6% – 99.9% identical between individuals and without clear boundaries between groups.
There is disagreement if certain extinct members of the genus, namely Neanderthals, should be included as a separate species of humans or as a subspecies of H. sapiens. [7] Human is a loanword of Middle English from Old French humain, ultimately from Latin hūmānus, the adjectival form of homō ('man' – in the sense of humanity). [9]
Most of them were coined since the mid 20th century in imitation of Homo sapiens in order to make some philosophical point (either serious or ironic), but some go back to the 18th to 19th century, as in Homo aestheticus vs. Homo oeconomicus; Homo loquens is a serious suggestion by Herder, taking the human species as defined by the use of ...
In case of humans, the sentence "the human races all form part of one single subspecies", meaning that they are not as wide apart to be considered different subspecies, makes scientific sense, and so by implication, the termina "subspecies" and "race" mean something different.--2001:A60:159F:A401:58D9:7B9E:2E9E:966D 14:00, 28 August 2014 (UTC)
Human behavior is the potential and expressed capacity (mentally, physically, and socially) of human individuals or groups to respond to internal and external stimuli throughout their life. Behavior is driven by genetic and environmental factors that affect an individual.
