What is sociobiology primarily concerned with?

Sociobiology is primarily concerned with understanding how biological factors, including genetics and evolution, influence social behaviors and structures within species, particularly humans. This field combines sociology and biology, asserting that many social behaviors have evolutionary origins and are shaped by the need for survival and reproduction. By examining behaviors such as aggression, altruism, mating practices, and parenting, sociobiologists explore how these traits are inherited and how they may have developed over time as adaptive strategies in social contexts.

The other options, while related to aspects of human behavior, focus on different domains. The psychological traits relate more to individual cognition and emotion rather than sociobiological frameworks. Economic factors pertain to societal structures and their economic dynamics, emphasizing resource distribution rather than biological imperatives. Cultural impacts examine learned behaviors and social norms that vary across societies but do not inherently focus on the biological basis of those behaviors. Thus, the selection of biological influences on social behavior accurately captures the essence of what sociobiology studies.
