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 ]

[1] [2] Therefore, a strain (within the honey bee context) is a lower-level taxonomic rank used at the intraspecific level within a race of a subspecies. Strains are often seen as inherently artificial concepts, more usually within biology as characterized by a specific intent for genetic isolation, [3] however, within beekeeping circles ...
It is the most widely used "genetic background" for genetically modified mice for use as models of human disease. They are the most widely used and best-selling mouse strain due to the availability of congenic strains, easy breeding, and robustness. [1] The median lifespan of C57BL/6 mice is 27–29 months and the maximum lifespan is about 36 ...
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]
The Mismeasure of Man is a 1981 book by paleontologist Stephen Jay Gould.The book is both a history and critique of the statistical methods and cultural motivations underlying biological determinism, the belief that "the social and economic differences between human groups—primarily races, classes, and sexes—arise from inherited, inborn distinctions and that society, in this sense, is an ...
First studied as an adaptive mechanism specific to humans, [1] cognitive specialization has since evolved to encompass many behaviors in the social realm. Organisms have evolved over millions of years to become well-adapted to their habitats; this requires becoming specialized in behaviors that improve an organism's likelihood of survival and reproduction.
