Orangutans, the mammals that take the longest to have a calf

The intergenesic interval (the time from one birth to a potential next pregnancy.) of orangutans is the largest of all primates and mammals: 6-8 years.

During all this time the offspring are very dependent on the mother because they need a long learning period in order to survive on their own. For instance, they learn how to climb, what to eat and how to get food, to identify and to avoid possible predators, etc.
