Parallel evolution across replicate populations has provided evolutionary biologists with
iconic examples of adaptation. When multiple populations colonize seemingly similar …

Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

The rediscovery of Mendel's work showing that the heredity of phenotypes is controlled by
discrete genes was followed by the reconciliation of Mendelian genetics with evolution by …

Coupling has emerged as a concept to describe the transition from differentiated
populations to newly evolved species through the strengthening of reproductive isolation …

Ecologists and evolutionary biologists are well aware that natural and sexual selection do
not operate on traits in isolation, but instead act on combinations of traits. This long …

The three-spined stickleback (Gasterosteus aculeatus) is an important model system for the
study of parallel evolution in the wild, having repeatedly colonized and adapted to …

The study of parallel ecological divergence provides important clues to the operation of
natural selection. Parallel divergence often occurs in heterogeneous environments with …

Local adaptation leads to differences between populations within a species. In many
systems, similar environmental contrasts occur repeatedly, sometimes driving parallel …

Biologists have long been intrigued by apparently predictable and repetitive evolutionary
trajectories inferred across a variety of lineages and systems. In recent years, high …

Parallel evolution can be expected among closely related taxa exposed to similar selective
pressures. However, parallelism is typically stronger at the phenotypic level, while genetic …
