Genome-scale sequence data have invigorated the study of hybridization and introgression,
particularly in animals. However, outside of a few notable cases, we lack systematic tests for …

In nature, closely related species may hybridize while still retaining their distinctive identities.
Chromosomal regions that experience reduced recombination in hybrids, such as within …

The process of speciation involves populations diverging over time until they are genetically
and reproductively isolated. Hybridization between nascent species was long thought to …

The three species of the Drosophila simulans clade—the cosmopolitan species, D.
simulans, and the two island endemic species, D. mauritiana and D. sechellia—are …

Regional rates of recombination often correlate with levels of nucleotide diversity, and either
selective or neutral hypotheses can explain this relationship. Regional recombination rates …

As whole-genome sequence assemblies accumulate, a challenge is to determine how these
can be used to address fundamental evolutionary questions, such as inferring the process of …

Abstract North American populations of Drosophila melanogaster derive from both
European and African source populations, but despite their importance for genetic research …

The phylogenetic relationship of the now fully sequenced species Drosophila erecta and D.
yakuba with respect to the D. melanogaster species complex has been a subject of …

While recombination is widely recognized to be a key modulator of numerous evolutionary
phenomena, we have a poor understanding of how recombination rate itself varies and …

Hybridization and gene flow between species appears to be common. Even though it is
clear that hybridization is widespread across all surveyed taxonomic groups, the magnitude …
