Cryptic genetic variation revealed by diet uncovers a trade-off between growth and telomere length.

Abstract excerpt

Evolutionary theory predicts that variation in longevity persists due to trade-offs between early-life fitness traits (e.g., growth or fecundity) and long-term somatic maintenance. However, such trade-offs can be difficult to detect and may often become apparent only under certain conditions. For instance, developing in novel or atypical environments may alter the genetic architecture of traits, revealing...
