Bigger Brains and Enhanced Immunity: Keys to Mammalian Longevity
Recent research from the University of Bath reveals that larger brains and robust immune systems contribute to longer lifespans in mammals. Analyzing the genomics of 46 species, the study found that species with more complex immune-related genes and larger brains tend to live longer, suggesting evolutionary advantages.

According to groundbreaking research led by the University of Bath, mammals with larger brains and more complex immune systems enjoy longer lifespans. The international team investigated evolutionary differences across 46 mammal species and discovered that investment in immune-related genes corresponds with enhanced longevity.
The study, published in the journal Scientific Reports, highlights broad genomic changes in the evolution of longer lifespans. These findings emphasize that not just individual genes but entire gene families associated with the immune system are pivotal. This genetic architecture shapes maximum lifespan potential, offering insights into why some species surpass others in longevity.
Dr. Benjamin Padilla-Morales, a key researcher from the Milner Centre for Evolution, elucidated, 'While larger brains have long been linked to longer lifespans, our study uncovers the unexpected role of the immune system in promoting longevity across mammals.' The research team plans further exploration into cancer-related genes to deepen understanding of lifespan variances among mammals.
