A new study suggests that zoo penguins age faster biologically than their wild counterparts, despite living longer overall. Researchers found that a 15-year-old zoo penguin can have the biological profile of a 20-year-old wild penguin, based on epigenetic analysis of DNA methylation. The difference is linked to lifestyle factors. Zoo penguins benefit from consistent food, Veterinary care, and protection from predators, but they also experience reduced physical activity, altered diets, and disrupted natural rhythms. These conditions may accelerate aging at the cellular level, similar to patterns seen in humans with sedentary, Western lifestyles.
The study compared wild and captive king penguins and found that zoo penguins live longer on average but show signs of faster biological aging. Researchers believe these findings provide valuable insight into how lifestyle influences aging and highlight the importance of balanced diet and exercise for both animals and humans.
