What is it?Edit
Adaptive radiation is an evolutionary process which means a single ancestral form that diversifies into several or many different types.
Examples in NatureEditThere are several well-known examples of adaptive radiation but the most famous of these is Darwin's finches.
Darwin observed about 15 species of birds often classified as the sub group Geospizinae. They are not true finches and show morphological variation based on
food type (Grant, 1986).
“The African cichlid fish radiations are the most diverse extant animal radiations and provide a unique system to test predictions of speciation and adaptive radiation theory” (Seehausen, 2006).
