Question

Deviation of homologous organs are caused by

• A. Time consequence along
• B. Gradual changes in structure
• C. Drastic changes in structure
• D. No changes in basic structure

Answer 1

The correct option is B Gradual changes in structure

Starting from a common ancestor, homologues show gradual changes, retaining the overall basic structure and not deviating drastically.

So, the correct answer is 'Gradual change in structure'
