A theory that can explain this finding from an evolutionary perspective is the parasite-stress theory which explains that an increase of infectious disease can cause humans to evolve selectively according to these pressures. Evidence also shows that as disease risk gets higher, it puts a level of stress on mating selection and increases the use of polygamy. In regions such as Sub-Saharan Africa the use of polygyny is commonly practiced as a consequence of high sex-ratios more males per females and passing on heterozygous diverse genetics from different females to offspring. Another reason that polygynous communities have larger age-gaps between spouses is that intrasexual competition for females increases as fewer females remain on the marriage market with males having more than one wife eachtherefore the competitive advantage values younger females due to their higher reproductive value. Smaller than average age-gaps[ edit ] In Western societies such as the US and Europe, there is a trend of smaller age-gaps between spouses, reaching its peak average in Southern Europe of 3. Using the same pathogen-stress model, there is a lower prevalence of disease in these economically developed areas, and therefore a reduced stress on reproduction for survival. Additionally, it is common to see monogamous relationships widely in more modern societies as there are more women in the marriage market and polygamy is illegal throughout most of Europe and the United States.
