The relative evolutionary roles of adaptive and non-adaptive processes remain a central
question in population genetics. Resolution of this debate has been difficult as an …

Genetic variation is the fuel of evolution, with standing genetic variation especially important
for short-term evolution and local adaptation. To date, studies of spatiotemporal patterns of …

Since the pioneering work of Dobzhansky in the 1930s and 1940s, many chromosomal
inversions have been identified, but how they contribute to adaptation remains poorly …

The rates of mutation, recombination, and transposition are core parameters in models of
evolution. They impact genetic diversity, responses to ongoing selection, and levels of …

Novel genes are essential for evolutionary innovations and differ substantially even between
closely related species. Recently, multiple studies across many taxa showed that some …

A long-standing enigma concerns the geographic and ecological origins of the intensively
studied vinegar fly, Drosophila melanogaster. This globally distributed human commensal is …

The cohabitation of Drosophila melanogaster with humans is nearly ubiquitous. Though it
has been well established that this fly species originated in sub-Saharan Africa, and only …

Meiotic drive supergenes are complexes of alleles at linked loci that together subvert
Mendelian segregation resulting in preferential transmission. In males, the most common …

To advance our understanding of adaptation to temporally varying selection pressures, we
identified signatures of seasonal adaptation occurring in parallel among Drosophila …

Abstract Background The piwi-interacting RNAs (piRNAs) are small non-coding RNAs that
specifically repress transposable elements (TEs) in the germline of Drosophila. Despite our …
