Please help i am giving away brainiliest Which of the following is necessary in order for natural selection to act on a
population?

A. selective pressures that favor certain individuals
B. asexual reproduction through mitosis
C. equal chance of survival for all individuals
D. decrease in diversity through genetic drift

No dam links

A

Explanation:

Natural selection occurs when an environment makes organisms with certain traits more likely to survive and reproduce.

Asexual reproduction results in no genetic variation (meaning differences in traits, also called divserity). Genetic variation must be present for certain organisms to be better suited to their environment, because in its absence all organisms share the same traits. This rules out B, C, and D. I hope this helps :)

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
