Biology Question on evolution
Which of the following are homologous organs
Wings of birds & Locust
Wings of birds (Sparrow) & Pectoral fins of fish
Wings of bat & Butterfly
Legs of frog & Cockroch
Wings of birds (Sparrow) & Pectoral fins of fish
Solution
The correct option is (B) : Wings of birds (Sparrow) & Pectoral fins of fish
Homologous organs are those that have a common ancestor and fundamental structure but may vary in outward form and function. The pectoral fins of fish and the wings of birds are two examples of similar organs. Organs that differ in their anatomical structure yet operate similarly are referred to as analogous organs. Similar organs include the wings of birds and locusts, the wings of bats and butterflies, the pectoral fins of sharks, and the flippers of dolphins.
