Question

How is adaptive radiation both convergent evolution different?

Answer 1

Changes in a species in response to different environmental conditions is called adaptive radiation. Most famous example of this are the Darwin's finches found on Galapagos Islands. All the finches originated from a common ancestor but their beaks are adapted according to their diet.

When two completely different species develop similar traits to adjust with the similar environmental conditions, it is called convergent evolution.

Answer 2

$\bf \:\large \purple{ᎪꪀsωꫀᏒ :-}$

In the case of convergent evolution, several organisms converge/share a common environment. Such change assists in their survival and modifies the morphology or displays analogous organs. In the case of adaptive radiation, an organism comes out of its existing habitat and travels to a completely new environment.
