Plasticity can either shield or fuel evolution in new environments
In short: Researchers exploring evolutionary theory found that phenotypic plasticity—the ability of an organism to change its traits in response to the environment—plays a complex role in survival. Depending on whether the response is adaptive or non-adaptive, plasticity can either hide genetic differences from natural selection or create new opportunities for populations to evolve when they encounter changing conditions.
The study suggests that adaptive plasticity is most likely to facilitate rapid evolution if the resulting traits are close to the new environmental optimum. Conversely, non-adaptive responses to stress might push phenotypes further from the optimum or release hidden genetic variation that could potentially lead to fitter outcomes by chance.
This theoretical analysis explores how different types of plasticity uniquely influence adaptive evolution, though it remains a conceptual framework rather than an empirical observation.
Why it matters: Understanding whether a trait change is adaptive or non-adaptive is key to predicting how species evolve.
