Question

Two organisms occupying a particular geographical area (say desert) show similar adaptive strategies. Taking examples, describe the phenomenon.

Answer 1

Convergent evolution

The type of evolution where organisms, present in the same environment, have evolved causing their structurally different body parts to have the same type of functions is called convergent evolution.
