Text Solution

Verified by Experts

The correct Answer is:
A
Carolus Linnaeus called humans as homo sapiens or wise men and placed them along with apes and monkeys.There are certain similarities between human and chimanzee.These are-
(i)RNA content of diploid cells is similar
(ii)DNA matching shows that human similarity is 100% with chimpanzee and
(iii)banding pattern of chromosomes shows very little differencer in chromosomes 3 and 6 between humans and chimpanzee.Thus it can be concluded that among the primates,chimpanzee is the closest relative of the present day humans.
