C. Evolution occurs at the population level
Evolution means the cumulative chnages that occur to the population over time, the process of evolution occurs only in population but not in individual.It involves the changes in gene frequencies in a gene pool.
Organisms or population will adapt to an environment for the
survival or they die. These are 4 mechanisms of evolution they are
natural selection, mutation, genetic drift and gene flow.
Maring is always not random in a population because non random
mating can also occur sometimes because one organisms choose to
mate with another based on certain traits.
