Change accelerates stalled evolution

A new manuscript will come out the end of this week.

Researchers of FOM Institute AMOLF and Laboratoire Interdisciplinaire de Physique in Grenoble (France) have shown that the evolution of bacteria can be accelerated when their environment fluctuates in time. The research gives new insights in the evolutionary limitations of organisms and the positive effect of changing conditions, and leads to new suggestions for the evolutionary optimization of biotechnological processes. The work also reveals a flip-side, because evolutionary acceleration can also be detrimental in some cases. For example, the alternating use of antibiotics could increase the risk that bacteria more rapidly evolve resistance against antibiotics. The results will be published November 13 in PNAS.
