Grand-parenting hypothesis, английский
This is the supposition that is abruptly terminating reproduction at a particular age (menopause) and prolonged survival of human females after menopause may have been selected for because of better success in child-rearing (and hence the survival of the gene pool) when older women focus their resources on the welfare of their grandchildren and thereby increase their likelihood of survival of the tribe, rather than investing energy in producing more and more children of their own, and potentially compromising the reproductive success of their more mature offspring.
Gompertz model, английский
A class of statistical models first proposed by the nineteenth-century british actuary benjamin gompertz, in which the hazard rate for death rises exponentially with increasing age of the organism (at least after an initial period of high risk of mortality at birth and infancy and much lower risk in late childhood and adolescence). today, the wibel model is superior to the gompertz model, as it more accurately explains observed demographic data.
