Discuss Theories of Parental Investment in Relationships

Extracts from this document...


´╗┐Parental investment Female investment in a child is usually greater. This is because female?s have limited offspring, whereas men can have potentially an unlimited offspring, as well as this, females also make a greater pre and postnatal commitment. The female must carry and nourish the child for 9 months, and then continue to care for the baby once it is born, as the child cannot get this care from the male, the male?s investment is much less, as the male can ?opt out? where the mother cannot.
