Epigenetic ‘experiments’ — changes resulting from external rather than genetic influences — suggest that the body’s physiological responses to hardship could be inherited, although the underlying mechanism has been a mystery. Now researchers have discovered a genetic mechanism that passes on the body’s response to starvation to subsequent generations of worms, with potential implications for humans also exposed to starvation and other physiological challenges.
