Evolutionary Mismatch And What To Do About It: A Basic Tutorial
... Evolutionary mismatch is a state of disequilibrium between an organism and its environment. In a classic case of mismatch, adaptations that contributed to survival and reproduction in previous environments become relatively maladaptive in a changed environment, a situation that can only be addressed ...

THE EVOLUTION OF PARASITES IN RESPONSE TO TOLERANCE
... The evolution of type I tolerance is likely to increase disease prevalence (Figs. 4A, D). This is due, in part, to the lower death rate of infected hosts, which also increases the opportunities for disease transmission (Roy and Kirchner 2000). The reduction in virulence associated with the evolution ...
