Assertion (A): A group of apes split into two smaller groups - one evolved into the modern gorillas, and the other into the modern chimpazees and human beings.
Reason (R): Bipedal locomotion is advantageous because it frees forelimbs for more actions.

The correct option is B Both A and R are correct and R does not explain A
The early primates evolved into monkeys which further evolved into primitive apes. A group of apes split into two groups - one evolved into the modern gorillas, and the other into the chimpanzees. The group of chimpanzees parted ways and evolved into modern chimpanzees and modern human beings. During this evolution, the forelimbs of apes got modified, resulting in bipedalism. However, this is not the reason for the evolution of apes into humans.
