Hybridization alters the shape of the genotypic fitness landscape, increasing access to novel fitness peaks during adaptive radiation.

eLife - 26 May 2022

Abstract excerpt

Estimating the complex relationship between fitness and genotype or phenotype (i.e. the adaptive landscape) is one of the central goals of evolutionary biology. However, adaptive walks connecting genotypes to organismal fitness, speciation, and novel ecological niches are still poorly understood and processes for surmounting fitness valleys remain controversial. One outstanding system for addressing these...
