Question

Some well-known researchers have claimed that group selection theory is required if we are to explain why people have the capacity to behave generously, nicely, and morally to other members of their group whereas the selfish side of human behavior has been caused by natural selection. What is wrong with this claim?

a. Group selection theory contradicts natural selection
b. Group selection theory is the only explanation for human behavior
c. Altruistic behavior can also be explained by kin selection
d. Group selection theory has been proven to be false

Answer 1

The incorrect claim is that group selection theory is the sole explanation for altruistic behaviors, ignoring kin selection and evolutionary game theory's contributions within sociobiology to understanding such behaviors.

Step-by-step explanation:

The claim that group selection theory is required to explain why people behave generously and morally, while natural selection explains selfish behavior, is not entirely accurate. Altruistic behavior among humans and non-human animals can be explained through other theories such as kin selection and evolutionary game theory. The discussion around group selection versus natural selection, kin selection, and the impacts on altruism and genetic determinants of behavior is part of the broader field of sociobiology, which studies the biological basis of social behavior. Ultimately, behaviors that improve an individual's chances of passing on their genes, which may include altruistic actions towards kin, are favored by natural selection.
