Cambridge Study Reveals Humans Are More Monogamous Than Meerkats, Yet Fall Short of Beavers

A recent study from the University of Cambridge has shed light on the monogamous tendencies of humans, suggesting that while we are more monogamous than meerkats, we still rank lower than beavers.

The research analyzed the prevalence of full siblings versus half-siblings within various species to measure their inclination towards monogamous behavior. It found that humans rank seventh among eleven species noted for monogamy.

Humans Rank Lower Than Beavers

Dr. Mark Dyble, who conducted the study, commented, "There is a premier league of monogamy, where humans sit comfortably, while the majority of mammals display a more promiscuous mating strategy." The study indicated that human rates of full sibling relationships align closely with those of socially monogamous mammals.

Using a computational model, Dyble assessed monogamy ratings across species based on genetic studies and archaeological evidence. The results revealed a 66% prevalence of full siblings among humans, with meerkats at 60% and beavers at 73%. The closest species to humans in monogamous behavior were white-handed gibbons at 63.5%.

Exploring Monogamous Behavior in Nature

Monogamy has been a subject of intrigue for philosophers and anthropologists alike, who often debate whether it is a natural inclination or a societal construct. Interestingly, while monogamous behavior is rare in mammals, it is more common in bird species, with about 90% forming lifelong bonds.

Some mammals, such as grey wolves, Eurasian beavers, and gibbons, are known to form lasting partnerships. Though monogamy exists in the animal kingdom, it remains a relatively uncommon phenomenon.
