Did monogamy develop due to sexually transmitted diseases?

It is highly probable that sexually transmitted infections may have contributed to the spread of monogamy among mankind, mathematicians at the University of Waterloo, Canada, calculated.

In prehistoric society, venereal diseases could have been life-threatening, so monogamy was the safest way of life here. Indeed, the authors of a study published in the journal Nature came to this conclusion using statistical tools while modeling the sexual habits and spread of diseases of ancient communities of different sizes.

Our analysis has shown that in a natural system, a factor such as the spread of infectious diseases can have a major impact on the development of social norms.”Said the research leader Chris belly.

According to the professor of applied mathematics, this is a good example of how mathematics can help us not only in forecasting but also in understanding the past. belly In the initial hunter-gatherer communities, where up to 30 sexually mature adults could live together, sexually transmitted infections disappeared in a short time, many times with the death of those infected. In larger, overlapping communities, however, they were more likely to spread and wreak havoc.

In the next step, groups prescribing monogamy pushed the more sick, multi-partner communities into the background.

Infections did not only affect those living in a monogamous relationship, so this form came to the fore and could even punish polygamy over time. Our moral views have not developed in isolation, they increasingly appear to have been shaped by environmental conditions.”- summed up the Chris belly, with whom many religious people will envelopably disagree.

Is monogamy a historical injustice?
