Explanation

Carolus linnaeus called human as Homo sapiens or wise men and placed them along with apes and monkeys. There are certain similariting between human and chimpanzee. 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 difference 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.
