How long does it take for a baby monkey to be born?

Your question seems to be based on misinformation. Monkeys, just like humans, undergo a gestational period that varies depending on the species. Most monkey species have gestation periods ranging from two to six months. For example, marmosets give birth after a little over two months, while baboons have gestation periods closer to six months. It's essential to research specific monkey species to obtain accurate information regarding their pregnancy and birth durations.
