Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

Hybridization is an evolutionary phenomenon that has fascinated biologists for centuries.
Prior to the advent of whole-genome sequencing, it was clear that hybridization had played …

Understanding why some evolutionary lineages generate exceptionally high species
diversity is an important goal in evolutionary biology. Haplochromine cichlid fishes of Africa's …

Although species are central units for biological research, recent findings in genomics are
raising awareness that what we call species can be ill-founded entities due to solely …

Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

Hybridization may drive rare taxa to extinction through genetic swam**, where the rare
form is replaced by hybrids, or by demographic swam**, where population growth rates …

An ordered draft sequence of the 17-gigabase hexaploid bread wheat (Triticum aestivum)
genome has been produced by sequencing isolated chromosome arms. We have annotated …

Summary The Qinghai–Tibet Plateau (QTP) sensu lato (sl), comprising the platform, the
Himalaya and the Hengduan Mountains, is characterized by a large number of endemic …

Darwin's theory of sexual selection fundamentally changed how we think about sex and
evolution. The struggle over mating and fertilization is a powerful driver of diversification …

As populations diverge, genetic differences accumulate across the genome. Spurred by
rapid developments in sequencing technology, genome-wide population surveys of natural …
