Question

multiple choice question
according to the evolutionary theory of aging, natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults because natural selection
o enables the survival of free radicals.
o causes our cells to stop dividing.
o is limited as a theory that encompasses the life span.
o is linked to reproductive fitness.

Explanation:

According to the evolutionary theory of aging, natural selection acts mainly on traits that affect reproductive fitness. Once an organism has passed its reproductive years, natural selection has less influence. Harmful conditions and nonadaptive characteristics that appear late in life (after the reproductive period) are not strongly selected against because they do not significantly impact the organism's ability to reproduce and pass on genes.

Answer:

is linked to reproductive fitness.
