From meerkats to macaques, social animals tend to live longer, take more time to reach maturity, and have more extended reproductive periods than their more solitary counterparts, according to research from the University of Oxford.

However, living in social groups comes with clear tradeoffs. On one hand, social animals can share resources, protect each other from predators, and help raise offspring together. On the other hand, they face increased risks of disease transmission, competition for resources, and social conflicts. Yet despite these challenges, scientists say the benefits of social living appear to outweigh the costs.

Rather than simply categorizing animals as either social or non-social, the researchers developed a novel spectrum of sociality with distinct levels. At one end are solitary animals like tigers and cheetahs, which spend most of their time alone except for breeding. In the middle are “gregarious” animals like wildebeest and zebras that form loose groups. At the far end of the spectrum are highly social species like elephants, most primates, and honeybees, which form stable, organized groups with complex social structures.

The findings have particular relevance in our post-COVID era, where humans have experienced firsthand the impacts of social isolation.

Lead author Rob Salguero-Gómez says, “This study has demonstrated that species that are more social display longer life spans and reproductive windows than more solitary species. In a post-COVID era, the impacts of isolation have been quite tangible to humans. The research demonstrates that being more social is associated with some tangible benefits.”
