Females frequently mate with several males, whose sperm then compete to fertilize
available ova. Sperm competition represents a potent selective force that is expected to …

What are the causes of natural selection? Over 40 years ago, Van Valen proposed the Red
Queen hypothesis, which emphasized the primacy of biotic conflict over abiotic forces in …

De novo gene birth is the process by which new genes evolve from DNA sequences that
were ancestrally non-genic. De novo genes represent a subset of novel genes, and may be …

Comparative analysis of multiple genomes in a phylogenetic framework dramatically
improves the precision and sensitivity of evolutionary inference, producing more robust …

The field of molecular evolution has experienced explosive growth in recent years due to the
rapid accumulation of genetic sequence data, continuous improvements to computer …

Studies of evolution at the molecular level have experienced phenomenal growth in the last
few decades, due to rapid accumulation of genetic sequence data, improved computer …

Across diverse taxa, seminal fluid proteins (Sfps) transferred at mating affect the
reproductive success of both sexes. Such reproductive proteins often evolve under positive …

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

Successful reproduction requires contributions from both the male and the female. In
Drosophila, contributions from the male include accessory gland proteins (Acps) that are …

Sexual reproduction requires coordinated contributions from both sexes to proceed
efficiently. However, the reproductive strategies that the sexes adopt often have the potential …
