Question

question 8 of 25
what is an effect of adaptive radiation?
a. geographical isolation
b. the rate of speciation decreases
c. many new species form
d. mass extinction

Explanation:

Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, creates new challenges, or opens new environmental niches. This leads to the formation of many new species. Geographical isolation is a cause of speciation rather than an effect of adaptive radiation. Adaptive radiation increases the rate of speciation, not decreases it. Mass - extinction is not an effect of adaptive radiation.

Answer:

C. Many new species form
