  2. Epigenetic clock - Wikipedia

    en.wikipedia.org/wiki/Epigenetic_clock

    In general, biological aging clocks and biomarkers of aging are expected to find many uses in biological research since age is a fundamental characteristic of most organisms. Accurate measures of biological age (biological aging clocks) could be useful for testing the validity of various theories of biological aging,

  3. Biogerontology - Wikipedia

    en.wikipedia.org/wiki/Biogerontology

    Genetic theories of aging propose that aging is programmed within each individual's genes. According to this theory, genes dictate cellular longevity. Programmed cell death, or apoptosis, is determined by a "biological clock" via genetic information in the nucleus of the cell. Genes responsible for apoptosis provide an explanation for cell ...

    Overview, including some physiological parameters, of the human circadian rhythm ("biological clock"). Chronobiology is a field of biology that examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms. [1] These cycles are known as biological rhythms.

  8. Adult development - Wikipedia

    en.wikipedia.org/wiki/Adult_development

    Changes occur at the cellular level and are partially explained by biological theories of adult development and aging. [1] Biological changes influence psychological and interpersonal/social developmental changes, which are often described by stage theories of human development. Stage theories typically focus on "age-appropriate" developmental ...

  9. Evolution of ageing - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_ageing

    The theory is based on the idea that ageing occurs over time due to the damage of the DNA. As an example, studies of mammalian brain and muscle have shown that DNA repair capability is relatively high during early development when cells are dividing mitotically, but declines substantially as cells enter the post-mitotic state.
