Figure 1. Aging cells thrive in non-optimal environments. Whereas the aging cells in a population are at a competitive disadvantage during growth on media for which the organism is specialised, we observe that aging yeast cells have a competitive advantage in non-optimal conditions. This provides an unexpected selective advantage for aging cells when the population is exposed to non-optimal or fluctuating environments.
