Question

what is survival of the fittest?
genetic drift
natural selection
speciation
evolution

charles darwin

Explanation:

"Survival of the fittest" is a phrase that describes the concept of natural selection. Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. Genetic drift is random changes in allele frequencies, speciation is the formation of new species, evolution is the overall change in species over time (of which natural selection is a mechanism), frequency is a general term, and Charles Darwin was the scientist who proposed the theory of natural selection (he used the phrase "survival of the fittest" as a way to describe natural selection). So the correct option is the one related to natural selection.

Answer:

B. Natural Selection
