उत्तर
The given diagrams depict anatomical similarities between the human hand, foreleg of the ox, forelimb of the bat, and flipper of the whale.
- Anatomical evidence are the similarities in structures and anatomy between different organisms.
- The hand of human, foreleg of ox, flipper of the whale, and forelimb 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.
