Inter-species hybridization has been recently recognized as potentially common in wild
animals, but the extent to which it shapes modern genomes is still poorly understood …

While hybridization has recently received a resurgence of attention from systematists and
evolutionary biologists, there remains a dearth of case studies on ancient, diversified hybrid …

In the past two decades, genomic data have been widely used to detect historical gene flow
between species in a variety of plants and animals. The Tamias quadrivittatus group of North …

The shape of the tree of life is the result of shifting diversification rates, and identifying the
factors driving these shifts is one of the main aims in evolutionary biology. Various biotic and …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Many species have experienced dramatic changes in their abundance and distribution
during recent climate change, but it is often unclear whether such ecological responses are …

The idea that species boundaries can be semipermeable to gene flow is now widely
accepted but the evolutionary importance of introgressive hybridization remains unclear …

The incidence of introgression during the diversification process and the timespan following
divergence when introgression is possible are poorly understood in the neotropics where …

Integration of molecular methods, ecological modeling, and statistical hypothesis testing are
increasing our understanding of differentiation within species and phylogenetic relationships …

If all nucleotide sites evolved at the same rate within molecules and throughout the history of
lineages, if all nucleotides were in equal proportion, if any nucleotide or amino acid evolved …
