Science Summary

This article was written based on the results of epigenetic experiments ( changes resulting from external rather than genetic influences) done on worms that suggested that "the body's physiological responses to hardship could be inherited" (science daily).Because " researchers have discovered a genetic mechanism that passes on the body's response to starvation to subsequent generations of worms" (science daily), implications can be made that humans exposed to starvation would have similar results. In the study, worms were starved and responded by producing small RNA,which regulate gene expression. The starvation-induced RNA were inherited by at least three subsequent generations. "We identified a mechanism called small RNA inheritance." (Dr. Rechavi). Small RNA inheritance allowed for the worms to pass on the "memory" of starvation.

This research could also be applied to to help people with physiological challenges including anorexia nervosa and bulimia nervosa. The results mentioned in this article are supported by similar experiments on rats that yielded the same results, deeming these conclusions reliable. The article included interesting information that, with extended experimentation, could be very helpful in the future.
