Rapid Parallel Adaptation to Anthropogenic Heavy Metal Pollution.
The impact of human-mediated environmental change on the evolutionary trajectories of wild organisms is poorly understood. In particular, capacity of species to adapt rapidly (in hundreds of generations or less), reproducibly and predictably to extreme environmental change is unclear. Silene uniflora is predominantly a coastal species, but it has also...Papadopulos, Alexander S.T. ; Helmstetter, Andrew J. ; Osborne, Owen G. ; Comeault, Aaron A. ; Wood, Daniel P. …

Genetic assimilation of ancestral plasticity during parallel adaptation to zinc contamination in Silene uniflora.
Phenotypic plasticity in ancestral populations is hypothesized to facilitate adaptation, but evidence is piecemeal and often contradictory. Further, whether ancestral plasticity increases the probability of parallel adaptive changes has not been explored. The most general finding is that ancestral responses to a new environment are reversed following adaptation (known as...
