Solution

Divergent evolution:

  1. In the process of divergent evolution two or more distinct species share a common ancestor from which they have been diverged, in this evolution the organs get modified to perform different functions according to the adaptation.
  2. For example, the skeletal framework of humans and horses looks similar because they have shared a common ancestor.

Convergent evolution:

  1. Convergent evolution is an evolutionary process in which unrelated organisms evolved structures, traits, or even morphological features that can have the same function.
  2. For example in the given question eyes of octopuses as well as mammals have the same function of vision which is why they can be said to have a convergent evolution.
  3. So, the eyes of octopuses and mammals are an example of convergent evolution.
