When gene flow swamps local adaptation, is it a dead end?

Evolution and adaptation are, by definition, multigenerational processes. An exciting recent insight has been the extent to which opposing forces of spatially diversifying selection and homogenizing gene flow can result in local adaptation at small spatial scales relative to average dispersal distances (Richardson et al. 2014). Multiple mechanisms that can account... [Read More]

You may be aware that many of the evolutionary biology’s most revered founders like Charles Darwin, RA Fisher, Francis Galton, William Bateson, and others, held questionable or even downright repugnant notions concerning evolutionary differences and hierarchies between races or the differently abled. But, even if you know this now, did... [Read More]

Feeling the heat across the generational divide

Park yourself on a beach towel at the coast for long enough, and you will likely experience a fraction of the environmental stress intertidal animals see on a regular basis. But they thrive in this environment, partially due to their physiological plasticity. Plasticity is a trait commonly seen in organisms... [Read More]
