Lecturer: Okay. So, scientists have seen this happen with certain monkeys, like for instance a species of monkeys that live in Japan. These monkeys live together, several dozen living together in a group. And, in these groups, the stronger males are always the first in line for the best food. If a weaker male monkey was to approach the lead males by himself when they're eating to try to get some food, the stronger males might get angry and try to hurt him. So the weaker males have to wait until the stronger males have eaten, and thus, don't end up getting as much food.
But, what a weaker male will sometimes do is, it'll actually borrow one of the babies in the group, a baby monkey, from its mother. It'll pick up the baby monkey and carry it along when it goes over to the lead males to try to get some food. And, remarkably, when the weaker male monkey has the baby monkey with it, the stronger monkeys allow the weaker male to get closer, maybe even share some of the food they're eating, and won't try to hurt it.
Explain how the example from the lecture illustrates the concept of buffering.
