उत्तर
- Different animal groups share comparable structures and anatomy. Human hands, bull forelimbs, bat patagiums, and whale flippers all have comparable internal architecture. All of these specimens share comparable bones and joints.
- There are no similarities in the external morphology. Also, each organ’s function varies depending on the animal. They might not have any structural similarities.
- However, similarities in their anatomy provide evidence that they may have a common ancestor.
- In this way, the anatomical evidence throws light on the process of evolution.
