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 …

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

The identification of signals of very recent positive selection provides information about the
adaptation of modern humans to local conditions. We report here on a genome-wide scan …

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

Sperm experience intense and varied selection that dramatically impacts the evolution of
sperm quality. Selection acts to ensure that sperm are fertilization-competent and able to …

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

The 15 members of the kallikrein-related serine peptidase (KLK) family have diverse tissue-
specific expression profiles and putative proteolytic functions. The kallikrein family is also …

Sexual reproduction is a fundamental biological process common among eukaryotes.
Because of the significance of reproductive proteins to fitness, the diversity and rapid …

It has been suggested that evolutionary changes in gene expression account for most
phenotypic differences between species, in particular between humans and apes. What …

Mitochondrial bioenergetics plays a key role in multiple basic cellular processes, such as
energy production, nucleotide biosynthesis, and iron metabolism. It is an essential system …
