Brain Size Correlates With Longer Lifespans

Study Links Larger Brains to Longer Lifespans in Mammals

• A University of Bath study found larger brains may correlate with longer lifespans and stronger immune systems in mammals.
• Research analyzed genomic data from 46 mammal species, identifying 236 gene families linked to maximum lifespan potential (MLSP).
• The study highlighted a connection between relative brain size and MLSP, with no link to gestation time or body mass.
• Genes associated with MLSP were more active and versatile in humans, suggesting a role in supporting longer lifespans.

The study suggests that both brain size and immune function are crucial factors in the evolution of long lifespans, revealing shared genetic mechanisms across species.
