New research across multiple species shows how aging shapes social behavior in ways that mirror human society.
Why it matters: Understanding how animals adapt their social connections as they age could provide insights into healthy aging in humans. This research challenges the assumption that becoming less social with age is always negative.
- Scientists have long studied social isolation in aging populations, but rarely across different species.
Key finding: Older animals, from red deer to house sparrows, actively reduce their social connections – often as a beneficial survival strategy rather than a deficit.
“Wild animals provide a good model system for considering the costs and benefits of changing social behavior with age.”

The process:
- Researchers analyzed 16 different studies across multiple species
- Used long-term tracking data from wild populations
- Compared social behavior patterns across age groups
Keep in mind: While reduced socialization appears beneficial in some cases, the impacts likely vary across species and circumstances.
Real-world impact: This research could inform human aging strategies, particularly around managing social connections to reduce disease exposure while maintaining necessary social bonds.
- The findings suggest that strategic social distancing in older age may be a natural and potentially beneficial behavior rather than something to be automatically counteracted.
TL;DR
- Animals naturally reduce their social connections as they age, often as an adaptive strategy rather than a deficit.
- This pattern appears across diverse species, from deer to fruit flies, suggesting it’s a fundamental biological phenomenon.
- Understanding animal social aging could help develop better approaches to healthy human aging.
