In the past decade, advances in genome sequencing have allowed researchers to uncover
the history of hybridization in diverse groups of species, including our own. Although the …

While hybridization was viewed as a hindrance to adaptation and speciation by early
evolutionary biologists, recent studies have demonstrated the importance of hybridization in …

The evolution of genomic incompatibilities causing postzygotic barriers to hybridization is a
key step in species divergence. Incompatibilities take 2 general forms—structural …

Aim Hybridization is thought to have played an important role in shaping the evolutionary
history of diverse island taxa. Here, we propose an ecological and evolutionary framework …

Natural selection is responsible for much of the diversity we see in nature. Just as it drives
the evolution of new traits, it can also lead to new species. However, it is unclear whether …

Spatially and temporally varying selection can maintain genetic variation within and
between populations, but it is less well known how these forces influence divergence …

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 …

Hybridization is an important mechanism of evolution. While hybrids often express inferior
traits and are selected against, hybridization can promote phenotypic variation and produce …

Progressive changes in the environment are related to modifications of the habitat.
Introducing exotic species, and interbreeding between species can lead to processes that in …

Tree species are often locally adapted to their environments, but the extent to which
environmental adaptation contributes to incipient speciation is unclear. One of the rarest …
