Yes, monkeys do have belly buttons. Just like humans, monkeys are mammals and share this common characteristic. When a monkey is born, it is attached to its mother through the umbilical cord, which provides nutrients and oxygen during its development in the womb. After birth, the umbilical cord is cut, leaving behind a small scar, which is what we recognize as a belly button.
This feature is part of the mammalian lineage, and it emphasizes the biological similarities between different species. Whether it’s a human, a monkey, or any other mammal, belly buttons serve as a reminder of the early life stages spent in the womb. So, the next time you see a monkey, you can be sure it has a belly button just like us!
