Sociobiology is a field of study that explores how biological factors influence social behavior in animals, including humans. It combines ideas from biology and sociology to understand how evolution shapes behaviors like cooperation, aggression, and mating. By examining the genetic and environmental factors that drive social interactions, sociobiologists aim to uncover the underlying reasons for various social structures and behaviors. One key concept in sociobiology is the idea of natural selection, which suggests that certain behaviors may enhance survival and reproduction. For example, altruistic behaviors, where individuals help others at a cost to themselves, can be explained through the lens of kin selection, where helping relatives increases the chances of shared genes being passed on to future generations.
