Question

Homologous organs indicate:

• A. Convergent Evolution
• B. Divergent Evolution
• C. Adaptive Radiation
• D. Natural Selection

Hint:

Homologous structures result from common ancestry, while analogous structures arise from convergent evolution, leading to similar functions.

Answer 1

The Correct Option is B

Understanding homologous organs.
- Homologous organs are structures that share a common anatomical origin but may perform different functions in different species. They arise due to inheritance from a shared ancestor.
Link between homologous organs and divergent evolution.
- Divergent evolution occurs when organisms of a common lineage adapt to various environmental conditions, leading to structural modifications while retaining fundamental similarities.
Example of homologous organs.
- A classic example is the forelimb structure in mammals, such as the human arm, the bat’s wing, and the whale’s flipper. Although these structures serve different purposes, they exhibit similar skeletal frameworks, demonstrating their shared ancestry.
Homologous organs provide strong evidence for divergent evolution, highlighting how species evolve distinct characteristics while maintaining structural commonalities.
