Question

The most intelligent ape is.
A. Gibbon
B. Orangutan
C. Gorilla
D. Chimpanzee

Answer 1

Hint: Apes are a branch of tailless simians originating in Africa and Southeast Asia from the Old World. They are the Old World monkeys' sister group, which together form the catarrhine clade. As formed by the impact of brachiation, they are distinguished from other primates by a wider degree of freedom of movement at the shoulder joint.

Complete answer:
Mostly, gibbons move by swinging. The Gibbons are renowned for their quick and graceful way of swinging their long arms through the forest.
Native to Indonesia and Malaysia, orangutans are great apes. The heaviest tree-dwelling mammal is the Orangutan.
Gorillas are terrestrial primates, mainly herbivorous, living in the forests of central Sub-Saharan Africa.

Several morphological and genetic modifications in the organism have contributed to evolution, leading to better adaptation. They have advanced hunting techniques involving teamwork, authority and rank, they are status aware, deceptive and capable of deception. Chimpanzees make instruments and use them to obtain food and for social displays.
They can learn to use symbols and understand elements of human language, including some relational grammar, number concepts, and numerical sequence concepts, and can prepare for a potential state or event spontaneously. So, relative to gibbons, orangutans and gorillas, they are the most intelligent apes.
So, the correct answer is “Option D”.

Note: Chimpanzees are unbelievably smart. They deal with instruments, engage with expressive vocalisations, and are effective problem-solvers. But as smart as chimps are, in contrast to our own, their brain capacity pales. A variety of factors help make the human brain superior to the chimps, but recent research shows that looser genetic regulation of human brain growth enables us to learn and adapt with greater resilience to our environment than our primate cousins.
