Humans May Have More in Common with Meerkats Than You Think — Especially in Love
When it comes to love and loyalty, humans might not belong with our primate relatives after all. A fascinating new study suggests that our pairing habits more closely resemble those of meerkats—yes, the small, social creatures that live in tight-knit groups in the desert. But here’s where it gets interesting: despite our reputation for complex relationships, humans score surprisingly high in the global "monogamy rankings" among mammals.
Scientists at the University of Cambridge created a kind of "league table" comparing how different species fare in terms of monogamy. The results? Humans sit comfortably in the upper tier, with about 66% of relationships showing monogamous patterns. That’s roughly the same as meerkats, and far higher than chimps or gorillas, whose scores barely reach 6%. However, the undisputed champions of lifelong commitment are the Californian mice, known for forming inseparable, enduring pairs that stick together for life. Talk about relationship goals!
According to Dr. Mark Dyble, who led the research, “There’s a premier league of monogamy, and humans are definitely in it.” He explains that while most mammals prefer a more promiscuous approach to mating, a select few—including us—have evolved to value long-term bonds.
Why would nature favor monogamy in some species but not others? The answer, researchers suggest, lies in cooperation. Forming a stable partnership can help animals raise offspring more effectively, share resources, and defend against rivals. This behavior, known as social monogamy, isn’t the same as total sexual exclusivity—it means that mates team up for at least one breeding season and often stick together to protect and nurture their young.
To measure just how monogamous humans are, Dr. Dyble studied different human populations throughout history, comparing the percentage of full siblings (sharing both parents) to half-siblings (sharing only one). He then ran the same analysis on over 30 other mammal species. The results placed humans at 66% full siblings—higher than meerkats (60%), but just behind beavers (73%). In sharp contrast, mountain gorillas scored 6%, chimpanzees 4%, and Soay sheep—a particularly promiscuous species—bottomed out at 0.6%. Standing proudly on top of the chart were, once again, Californian mice with a perfect 100%.
But here’s the part most people miss: being similar in monogamy levels doesn’t mean humans live like meerkats or beavers. Our social structure is entirely different. As Dr. Dyble told BBC News, “While our rates of full siblings are similar, the way we organize ourselves socially sets us apart. Most monogamous animals live as isolated pairs or in colonies. Humans, on the other hand, live in multi-male, multi-female communities where individual pair bonds form within larger, dynamic social networks.”
That unique structure complicates the story of human relationships. As Dr. Kit Opie from the University of Bristol (who wasn’t involved in the study) points out, this research adds another piece to the puzzle of how monogamy developed in our species. “Across cultures and history, humans consistently lean toward monogamy,” Opie says. Yet he also notes that our social behavior still shares deep similarities with chimpanzees and bonobos—it’s just that we evolved a different strategy for mating and family structure.
The findings, published in the Proceedings of the Royal Society: Biological Sciences, open up a new perspective on what it means to form bonds and build societies. Are humans truly monogamous by nature—or have we learned to be, shaped by culture and circumstance? And if we’re more like meerkats than our primate cousins when it comes to romance, what does that say about how love fits into evolution?
What do you think — are humans naturally built for monogamy, or do we just try to convince ourselves that we are? Share your thoughts and debate below — this one’s bound to stir up some opinions.
