Question

Statement 1: Speciation is a fast process.

Statement 2: Speciation may take place when variations are combined with geographical isolation.

• A. Both the statements are correct.
• B. Only statement 1 is correct.
• C. Both the statements are incorrect.
• D. Only statement 2 is correct.

Answer 1

The correct option is D Only statement 2 is correct.

• The formation of new and distinct species in the course of evolution is called speciation.
• Speciation is a slow process. Since the variations keep accumulating generation after generation. It usually takes few million years for speciation to take place.
• Variations when combined with geographical isolation ensures that only the organisms that have well-adapted to the changing conditions will survive. This can lead to the emergence of a new species (well-adapted organisms).
