Zoologist: Meerkats are desert mammals that live in groups and are believed to exhibit altruistic behavior. While the group is foraging, a single meerkat will stand guard, keeping watch for predators and giving loud warning cries when danger appears. However, this behavior is not true altruism: Meerkats on guard duty do not face a greater risk of being killed, and solitary meerkats will also stand guard.
