Question

Closest primate to man is
(a) Gorilla
(b) Rhesus monkey
(c) Orangutan
(d) Lemur

Answer 1

This is the largest living primate and is also a critically endangered species mainly found in the forest of central Sub-Saharan, Africa. These are social animals but when they feel threatened they can become aggressive towards humans.

Complete answer:
Out of the given options, the gorilla is the closest primate to man. Primate is a group of mammals that includes lemurs, lorises, tarsiers, monkeys, apes, and humans.
-For several years the scientists are trying to solve the mystery of how we humans originated. They were using chimpanzees as an invaluable source of clues.
-Now it is known that it's not a chimpanzee from which humans have evolved. They have spent time for millions of years evolving from our last common ancestor on its own path, just as we have done in evolving. So, it is clear that chimpanzees are still our closest living relatives.
-Humans share ${ 98.8 }$% of chimpanzee’s DNA. Researches are being continued to get an insight into our similarity, discovering the roots we both stem from.
-On the basis of the analysis done on the sequences of 7100 nucleotides found in a segment of DNA from the hemoglobin gene, the scientists have suggested that humans and chimpanzees are closer to one another as compared to chimpanzees and gorillas.
-In comparison, the result was at ${ 98.8 }$% of the bases matched in man and chimpanzee and ${ 97.9 }$% with gorilla and man. So, gorillas are the closest primates to man after chimpanzees then came the Rhesus monkeys, afterward orangutans, and lemurs.

So, the correct answer is,' Gorilla'.
