Answer 1

c. a rapid increase in the number of related species. Adaptive radiation refers to an event in which a particular linage of organism rapidly diversifies into newly formed lineages that have evolved with different adaptations.

Adaptive radiation can be defined as the process by which organisms diversify rapidly into new species from a common ancestral species. Any change in the environment conditions creates new challenges and the species become adaptable to the changes, survive and reproduce to increase in population.
