Evolutionary genomic studies find that reproductive protein genes, those directly involved in
reproductive processes, diversify more rapidly than most other gene categories. Strong …

Sexual dimorphism is one of the most prevalent, and often the most extreme, examples of
phenotypic variation within species, and arises primarily from genomic variation that is …

The evolution of costly traits such as deer antlers and peacock trains, which drove the
formation of Darwinian sexual selection theory, has been suggested to both reflect and affect …

Simple Summary The red palm weevil (RPW) Rhynchophorus ferrugineus (Coleoptera:
Curculionidae) is a species of beetle that depends on palm trees to complete its life cycle …

Callosobruchus maculatus is a major agricultural pest of legume crops worldwide and an
established model system in ecology and evolution. Yet, current molecular biological …

Sexually antagonistic (SA) genetic variation—in which alleles favored in one sex are
disfavored in the other—is predicted to be common and has been documented in several …

Seminal fluid proteins (SFPs) are a group of reproductive proteins that are among the most
evolutionarily divergent known. As SFPs can impact male and female fitness, these proteins …

Gene expression differences between males and females are thought to be key for the
evolution of sexual dimorphism, and sex-biased genes are often used to study the molecular …

The Y chromosome is theorized to facilitate evolution of sexual dimorphism by accumulating
sexually antagonistic loci, but empirical support is scarce. Due to the lack of recombination …

Sexual dimorphism is ubiquitous in nature but its evolution is puzzling given that the mostly
shared genome constrains independent evolution in the sexes. Sex differences should …
