Which of the following best describes the concept of adaptive radiation?
- A.Evolution of different species from a common ancestor in a new geographical area
- B.The process by which two species evolve to become more similar
- C.The gradual change in allele frequencies over time due to genetic drift
- D.The sudden extinction of a species due to environmental catastrophe
Show correct answer & step-by-step solution
Correct answer: A — Evolution of different species from a common ancestor in a new geographical area
Solution
- Adaptive radiation involves the rapid evolution of multiple species from a single common ancestor.
- This typically occurs when a population colonizes a new environment with diverse resources.
- Each lineage adapts to a specific niche, leading to morphological and functional divergence.
- Hence the answer is (A).
