1. It has long been theorized that mating preferences in many animal groups are driven by a need for offspring to survive and pass on genetic material. This leads to a dichotomy in terms of different mating strategies utilized by male and female members of the species. Female mating preferences are driven by the pursuit of security and protection for the female and her (typically single) offspring, while males are motivated to find the female(s) that will most likely lead to healthy offspring. In humans this manifests itself when we often see women pursuing older (more secure) men and men pursuing younger (more fertile) women. If this is true then we should see a tendency for older men to marry younger women. A random sample of 12 married couples was drawn from the population of married couples in the US (where age is roughly normally distributed). The ages of the husbands and wives are shown below.
