Question

Describe an example of adaptive radiation.

Answer 1

Adaptive radiation:

1. Adaptive radiation is a rapid increase in the number of species having a common ancestor.
2. It is characterized by great morphological and ecological diversity.
3. The main reason behind adaptive radiation is the adaptation of organisms to new ecological niches.

Example of adaptive radiation:

1. An example of adaptive radiation is Darwin's finches or the Galapagos finches.
2. It was found that during evolution, the morphology and size of the beaks of Darwin's finches changed.
3. Due to changes in their beak size their food habits also changed, few ate small animals or insects while others fed on plants.
