Question

In the following question a statement of assertion (A) is followed by a statement of reason (R).

A - Human beings are more closely related to apes than to monkeys.
R - All the three, monkeys, apes and humans have a common ancestry.

• A. Assertion and reason are true, and the reason is the correct explanation of the assertion
• B. Assertion and reason are true, and the reason is not the correct explanation of the assertion
• C. Assertion is a true statement but the reason is false
• D. Assertion and reason are false statements

Answer 1

The correct option is B Assertion and reason are true, and the reason is not the correct explanation of the assertion

Human beings, apes and monkeys, all three share the same common ancestry. The ancestors of Homo sapiens (human) diverged from the ancestors of other primates at varying times, and that means we are closely related to some primates, and more distantly related to others. The species diverged into two separate lineages from this common ancestor first. One of these lineages ultimately evolved into gorillas and chimpanzees, and the other evolved into early human ancestors called hominids.

Human beings share more than 98 percent of DNA with chimpanzees and bonobos (pygmy chimpanzees). Four blood groups A, B, AB and O are found in humans. The blood group A and B are also found in the apes but not in monkeys. All this evidence suggests that human beings are more closely related to apes than to monkeys.
