What do you realize about the evolution of altruism? Do you think you can pass this quiz? Altruistic behavior reduces the possibility that an individual will reproduce. The notion of group selection might explain the evolution of altruism, as Charles Darwin first presented it. The concept of group selection has been controversial throughout the history of evolutionary biology. Take this quiz and learn more about the evolution of altruism.
