Phylogenomics has revealed the remarkable frequency with which introgression occurs
across the tree of life. These discoveries have been enabled by the rapid growth of methods …

Studies of plants have been instrumental for revealing how new species originate. For
several decades, botanical research has complemented and, in some cases, challenged …

Sunflowers of the genus Helianthus are models for hybridization research and contain three
of the best-studied examples of homoploid hybrid speciation. To understand a broader …

Hybridization and resulting introgression can play both a destructive and a creative role in
the evolution of diversity. Thus, characterizing when and where introgression is most likely to …

Introgression is a common evolutionary phenomenon that results in shared genetic material
across non-sister taxa. Existing statistical methods such as Patterson's D statistic can detect …

Most species will not be able to migrate fast enough to cope with climate change, nor evolve
quickly enough with current levels of genetic variation. Exacerbating the problem are …

Genetic data contain a record of our evolutionary history. The availability of large-scale
datasets of human populations from various geographic areas and timescales, coupled with …

To understand how species evolve and adapt to changing environments, it is important to
study gene flow and introgression due to their influence on speciation and radiation events …

DNA introgressed from one species into another is typically deleterious at many genomic
loci in the recipient species. It is therefore purged by selection over time. Here, we use …
