Solution

  1. The given picture indicates the morphological evidence of evolution.
  2. Morphological evidence is based on the similarity of size, shape or structure of organs among a group of organisms proving that they evolved from the same ancestor.
  3. Other examples of evolutionary evidence: Anatomical evidence, paleontological evidence, vestigial organs, embryological evidence, connecting links.
  Is there an error in this question or solution?
