The two theories; non-adaptive, and adaptive, are used to explain the evolution of senescence, which is the decline in reproduction with age. [8] The non-adaptive theory assumes that the evolutionary deterioration of human age occurs as a result of accumulation of deleterious mutations in the germline. [8]
Biogerontology should not be confused with geriatrics, which is a field of medicine that studies the treatment of existing disease in aging people, rather than the treatment of aging itself. There are numerous theories of aging, and no one theory has been entirely accepted.

Previous research showed that resting energy use, or metabolic rate, didn’t change from ages 20 to 60. The new study’s findings don't contradict that. The new study’s findings don't ...
Under most assumptions, the mutation accumulation theory predicts that mortality rates will reach close to 100% shortly after reaching post-reproductive age. [10] Experimental populations of Drosophila Melanogaster, and other organisms, however, exhibit age-specific mortality rates that plateau well before reaching 100%, making mutation ...
