Question

Quizplus · Accepted Answer

Trivers' theory of parental investment suggests that siblings fight over limited resources that their parents can offer, such as attention, affection, and material resources. This behavior is considered normal as they are competing for the same resources. As brothers and sisters share half of their genetic material, it also makes sense for them to compete for parental investment. A and B are incorrect as the genetic relation between siblings does not necessarily make their behavior abnormal, and fighting between brother-sister pairs is also normal. D is incorrect as fighting between siblings is not solely motivated by the need for attention from parents, but also by other resources.
