Phenotypic plasticity drives local adaptation by disrupting a genetically integrated jaw apparatus in Trinidadian guppies.

Abstract excerpt

Consistently across clades, researchers find a high degree of covariation in the shape of disparate elements within the same individual, a pattern known as morphological integration. Although integration can help to maintain functionality of multi-component systems, it can also constrain long-term evolution. On shorter time scales, morphology is often shaped by plastic environmental responses; however, it remains...
