C. Monkeys are nocturnal; apes are diurnal.
D. Monkeys have no postorbital bar; apes do have a postorbital bar.

Answer :

Final answer:

The major difference between monkeys and apes is that monkeys have tails while apes do not. Apes are larger and more intelligent than monkeys, and they are all diurnal. These physical and behavioral distinctions help classify these primates into different groups.


Explanation:

Major Differences Between Monkeys and Apes

The primary difference between monkeys and apes lies in their physical characteristics and some behavioral aspects. Here are the key distinctions:

  • Monkeys have tails, while apes do not. This is one of the most notable differences. Monkeys, which include species such as macaques and capuchins, often possess long tails that aid in balance and climbing, whereas the entire group of apes, including gorillas and chimpanzees, lack tails.
  • Apes are generally larger in size and possess larger brains relative to their body size compared to monkeys. This structural difference also results in higher intelligence levels in apes.
  • Additionally, all apes are diurnal, meaning they are active during the day, while some monkeys may be nocturnal or have varying activity patterns.

In summary, the presence or absence of tails is a major and easily observable difference between these two groups of primates, alongside the distinctions in size and intelligence.
