🧬 How a Father’s Fitness Rewrites the Genetic Playbook
A fascinating look at how lifestyle choices might leave molecular signatures in our descendants — expanding heredity beyond traditional DNA inheritance.
New research suggests that a father’s exercise habits can biologically influence his offspring through RNA molecules carried in sperm. Experiments in mice show that physical activity changes microRNA expression in sperm, reprogramming embryonic gene regulation and producing offspring with greater endurance. These findings point to an epigenetic mechanism that allows paternal experiences to shape the health and performance of future generations.
