Adaptive radiation occurs when <u>organisms evolve from the same ancestor. This process takes place as a result of environmental changes or when they are introduced to or colonize a new environment.</u> These changes become challenges that force these individuals to adapt to these new conditions.

Therefore, <u>this results into a faster evolution that creates different new forms</u> that possess a diversity of variations adapted to their new feeding habits, environment, and behavioral needs.

<em>One of the most famous examples of adaptive radiation is the formation of new forms of Galapagos finches.</em> These striking finches, which arose from a common ancestor, evolved different beak sizes and shapes that were especially adapted to different types of food. As different as they may appear, they are closely related!
