The importance of whole-genome duplication (WGD) for evolution is controversial. Whereas
some view WGD mainly as detrimental and an evolutionary dead end, there is growing …

Parallel and convergent evolution offer some of the most compelling evidence for the
significance of natural selection in evolution, as the emergence of similar adaptive solutions …

Parallelism between evolutionary trajectories in a trait space is often seen as evidence for
repeatability of phenotypic evolution, and angles between trajectories play a pivotal role in …

Coloration facilitates evolutionary investigations in nature because the interaction between
genotype, phenotype and environment is relatively accessible. In a landmark set of studies …

Studying repeated adaptation can provide insights into the mechanisms allowing species to
adapt to novel environments. Here, we investigate repeated evolution driven by habitat …

The independent and repeated adaptation of populations to similar environments often
results in the evolution of similar forms. This phenomenon creates a strong correlation …

Sympatric adaptive phenotypic divergence should be underlain by genomic differentiation
between subpopulations. When divergence drives similar patterns of phenotypic and …

Studies of convergence in wild populations have been instrumental in understanding
adaptation by providing strong evidence for natural selection. At the genetic level, we are …

Although rapid phenotypic evolution has been documented often, the genomic basis of rapid
adaptation to natural environments is largely unknown in multicellular organisms …

When divergent populations interbreed, their alleles are brought together in hybrids. In the
initial F1 cross, most divergent loci are heterozygous. Therefore, F1 fitness can be …
