Evolutionary biologists have thought about the role of genetic variation during adaptation for
a very long time—before we understood the organization of the genetic code, the …

Laboratory studies have demonstrated that a single phenotype can be produced by many
different genotypes; however, in natural systems, it is frequently found that phenotypic …

Similar forms often evolve repeatedly in nature, raising long-standing questions about the
underlying mechanisms. Here, we use repeated evolution in stickleback to identify a large …

Genome sequencing enables answering fundamental questions about the genetic basis of
adaptation, population structure and epigenetic mechanisms. Yet, we usually need a …

Parallel adaptation provides valuable insight into the predictability of evolutionary change
through replicated natural experiments. A steadily increasing number of studies have …

Genome scans can potentially identify genetic loci involved in evolutionary processes such
as local adaptation and gene flow. Here, we show that recombination rate variation across a …

Gene flow has tremendous importance for local adaptation, by influencing the fate of de
novo mutations, maintaining standing genetic variation and driving adaptive introgression …

Dispersal and adaptation both allow species to persist in changing environments. Yet, we
have limited understanding of how these processes interact to affect species persistence …

Relative contributions of pre-existing vs de novo genomic variation to adaptation are poorly
understood, especially in polyploid organisms. We assess this in high resolution using …
