Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

Evolutionary changes in traits that affect both ecological divergence and mating signals
could lead to reproductive isolation and the formation of new species. Insect cuticular …

The National Research Council issued a report in 2009 that heavily criticized the forensic
sciences. The report made several recommendations that if addressed would allow the …

Divergent natural selection has been shown to promote speciation in a wide range of taxa.
For example, adaptation to different ecological environments, via divergent selection, can …

Dietary composition is known to have profound effects on many aspects of animal
physiology, including lifespan, general health, and reproductive potential. We have …

A combination of divergent natural and sexual selection is a powerful cause of speciation.
This conjunction of evolutionary forces may often occur when divergence is initiated by …

Sex differences in dioecious animals are pervasive and result from gene expression
differences. Elevated sexual selection has been predicted to increase the number and …

Speciation has been a major focus of evolutionary biology research in recent years, with
many important advances. However, some of the traditional organising principles of the …

Natural selection is notoriously dynamic in nature, and so, too, is sexual selection. The
interactions between phytophagous insects and their host plants have provided valuable …

Sexually selected traits contribute greatly to phenotypic diversity, yet we have historically
understood little about their genetic basis and how that basis may affect their evolution …
