Which of the following correctly explains why scientists believe that great apes like chimpanzees and gorillas are more closely related to humans than monkeys on an evolutionary timeline? a. apes are larger than monkeys and have long legs and no tails. b. apes have smaller brains than monkeys and are less social than monkeys. c. monkeys have larger brains than apes and are smaller in size. d. monkeys are larger than apes and have prehensile tails.

Scientists believe that great apes such as chimpanzees and gorillas are more closely related to humans based on the evolutionary timeline because apes are larger than monkeys and have long legs and no tails. Apes are known to have larger brains than monkeys which makes them so closely related to us. This fact cancels out B and C for the answer. Also, apes (gorillas, orangutans, etc.) are much larger than monkeys (mandrill, lesula, etc.). This right away cancels out option D. What's left is option A which features body parts and comparisons that are comparatively accurate towards humans. Hope this helped :))

Ans.

Chimpanzees and gorillas are considered as more closely related to humans as compared to monkeys. It is because apes have a larger brain, longer life-span, higher intelligence, longer legs and show absence of tails as humans, while monkeys have a smaller brain, short-life span, short legs, and tails.

Thus, the correct answer is option A). apes are larger than monkeys and have long legs and no tails.

2%? i tried finding the exact sorry if it's not 100% correct ; -;
