Researchers have discovered that the way mammals are socially organised is linked to their lifespan. Mammals live in various social groups, ranging from solitary animals to complex communities. The research shows that species with strong social cooperation often live longer than solitary animals. This may be related to the influence of social interaction on reproduction and survival.
Lifespan is thereby linked to the balance between growth and bodily maintenance. Species that mature quickly can indeed produce offspring sooner, but often have a shorter lifespan. Species with a social structure in which they help and protect each other usually have more time to reproduce and properly care for their young. As a result, their lifespan can increase.
These findings align with previous research showing that extremely social life forms, such as some bees and ants, also live longer. In mammals, therefore, social cooperation is an important factor for a longer lifespan. This helps us better understand which factors determine why some animal species live longer than others.
For people, this insight can inspire them to maintain social contacts and connectedness. Strong social networks may contribute to healthy and long-term ageing.
