(N/A) Adaptive radiation is an evolutionary process that produces new species from a single,rapidly diversifying lineage. This process occurs due to natural selection.
An example of adaptive radiation is Darwin's finches,found on the Galapagos Islands.
$A$ large variety of finches is present on the Galapagos Islands that arose from a single species,which reached this land accidentally.
As a result,many new species have evolved,diverged,and adapted to occupy new habitats.
These finches have developed different eating habits and different types of beaks to suit their feeding habits.
The insectivorous,blood-sucking,and other species of finches with varied dietary habits have evolved from a single seed-eating finch ancestor.
