प्रश्न
Explain the importance of Anatomical evidences with examples.
उत्तर
- Anatomical evidences are the similarities in structures and anatomy between different organisms.
- The hand of a human, foreleg of ox, flipper of whale, and forelimbs of bat appear different superficially or morphologically.
- Also, the function of these structures is different in different animals.
- However, there is a similarity in the structure of bones and bony joints in the organs of these animals.
- These similarities indicate that the animals evolved from a common ancestor thus providing proof of evolution.
