This definition of immortality has been challenged in the Handbook of the Biology of Aging, [1] because the increase in rate of mortality as a function of chronological age may be negligible at extremely old ages, an idea referred to as the late-life mortality plateau. The rate of mortality may cease to increase in old age, but in most cases ...
A life history strategy is the "age- and stage-specific patterns" [2] and timing of events that make up an organism's life, such as birth, weaning, maturation, death, etc. [3] These events, notably juvenile development, age of sexual maturity, first reproduction, number of offspring and level of parental investment, senescence and death, depend ...
The shape of their skull does not change into adulthood (only increasing in size), due to sexual dimorphism and an evolutionary change in the timing of development. [ 39 ] In some groups, such as the insect families Gerridae , Delphacidae and Carabidae , energy costs result in neoteny; many species in these families have small , neotenous wings ...
Maturity (geology), in petroleum geology; Maturation, as a threat to internal validity of an experiment; Tissue maturation, an aspect of developmental biology The final stages of cellular differentiation of cells, tissues, or organs
[18] [19] Andrew Arthur Abbie agrees, citing the gerontomorphic fleshy human nose and long human legs as contradicting the neoteny hominid evolution hypothesis, although he does believe humans are generally neotenous. [7] Brian K. Hall also cites the long legs of humans as a peramorphic trait, which is in sharp contrast to neoteny. [20]

Senescence (/ s ɪ ˈ n ɛ s ə n s /) or biological aging is the gradual deterioration of functional characteristics in living organisms. Whole organism senescence involves an increase in death rates or a decrease in fecundity with increasing age, at least in the later part of an organism's life cycle.
Adult development encompasses the changes that occur in biological and psychological domains of human life from the end of adolescence until the end of one's life. Changes occur at the cellular level and are partially explained by biological theories of adult development and aging. [1]
