Q. Which of the following is/are the benefits of Cheetah reintroduction project?
1.Restores historic evolutionary balance in ecosystem.
2.Can save endangered species of the grasslands / open forest eco-systems.
3Aid evolutionary natural selection force.
Select the correct answer from the codes given below;

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: D

Cheetah restoration is part of a prototype or model for the restoration of original cheetah habitats and their biodiversity. Bringing back a top predator restores historic evolutionary balance resulting in cascading effects on various levels of the ecosystem. 

For instance, the cheetah has been the evolutionary natural selection force that has shaped the adaptation of high speeds in Indian antelopes and gazelles. By restoring cheetah, India would also be able to save not only its prey base comprising certain threatened species, but also other endangered species of the grasslands / open forest eco-systems, some of which are on the brink of extinction.
