Different types of fore limbs ?
Solution:
The correct option is (1).
The forelimbs of all mammals like humans (A), cats (B), whales (C), and bats (D) have the same basic bone structure. They have inherited this pattern of their forelimbs from a common ancestor. However, these organs have evolved with time to perform different functions in them. In bats, forelimbs are modified into wings for the purpose of flying, which is an aerial adaptation.
