Question : The wings of a bird and an insect are
Option 1: homologous organs
Option 2: analogous organs
Option 3: vestigial organs
Option 4: rudimentary organs
Correct Answer: analogous organs
Solution : The correct answer is analogous organs.
The wings of birds and insects share structural similarities, suggesting a common function: flight. However, they originate from different anatomical structures and possess distinct compositions. Bird wings are modifications of forelimbs, featuring a skeletal framework supporting feathers composed mainly of keratin. In contrast, insect wings are extensions of the body wall, comprising thin, transparent membranes primarily made of chitin. Although chitin lacks the flexibility of feathers, it provides strength and lightness to insect wings.
