Answer :

GinnyAnswer

Final answer:

Adaptive radiation is the rapid evolution of a lineage to fill multiple ecological niches, increasing biodiversity.


Explanation:

Adaptive radiation is the rapid evolution of a lineage to fill multiple open ecological niches, as exemplified by Darwin's Finches on the Galapagos Islands. Through adaptive radiation, a single ancestral species diversifies into multiple specialized species, each occupying a distinct ecological niche. This process leads to the increase in biodiversity by allowing organisms to exploit various resources and habitats.
