Biologists Study Evolution of Animal Cooperation

Survival of the fittest is a simple reality in the game of life. Successful play necessarily requires a degree of selfishness, but across the animal kingdom species have evolved social behaviors. Why? Do they enhance survival?

“Many of us are really fascinated with the wide spectrum of social behavior we see across the diversity of animal taxa,” said Janis Dickinson, an evolutionary biologist at the University of California at Berkeley.
