Question

Quizplus · Accepted Answer

In more complex societies, property rights become more important, and controlling mating is a way of controlling property. By limiting premarital sex, societies can ensure that property is passed down through legitimate heirs and prevent illegitimate children from disrupting inheritance patterns. This is not the case in less complex societies, where property and inheritance may be less important. The other options (B, C, and D) are not sufficient explanations for the trend of greater restrictiveness towards premarital sex in more complex societies.
