Life can be unfair sometimes, where it can seem like someone is always two steps ahead of you. For this reason, humans and other primates evolved to support long-term cooperation, according to new research.
Finding new ways to chow down on a nice, juicy bug may have helped early humans develop advanced intelligence, researchers suggest in a recent study.
The silvery gibbon - an endangered primate found on an Indonesian island - sings long and complicated songs to invaders, mates, and family. Researchers now suggest that these apes may hold clues to how language developed in humans.
How patient a primate is may depend entirely on how it has evolved. Primates with larger bodies appear to be more willing to wait for large rewards, compared to smaller species who prefer immediate gratification. One researcher claims that these observations may help us better understand the patience of humanity as well.
