Question

Assertion (A): Speciation is a function of time and tropical regions got a long evolutionary time for species diversification as compared to temperate regions.

Reason (R): Temperate regions have undergone frequent glaciations in the past whereas tropical regions have remained relatively undisturbed for millions of years.

पर्याय

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

Explanation:

Tropical regions remained relatively undisturbed for long periods, giving species more time to diversify. Frequent glaciations in temperate regions disrupted populations and habitats.
