question 14 of 25
what is an effect of adaptive radiation?
a. new species
b. disruptive selection
c. mass extinction
d. genetic drift

Explanation:

Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms. This occurs when there are new ecological niches available. As a result of adaptive radiation, new species are formed. Disruptive selection is a type of natural selection (not an effect of adaptive radiation). Mass extinction is a large - scale dying out of species (opposite of what adaptive radiation promotes). Genetic drift is a change in allele frequencies due to chance (not a direct effect of adaptive radiation). So, the effect of adaptive radiation is new species.

Answer:

A. New species
