Many genes that mediate sexual reproduction, such as those involved in gamete
recognition, diverge rapidly, often as a result of adaptive evolution. This widespread …

Different loci within the genome of a single species can potentially coevolve in a manner that
is analogous to the Red Queen process among species. The major factor driving this …

When Darwin proposed that females shape evolution by being choosy in their choice of
male suitors, his Victorian contemporaries were shocked that he accorded so much …

The causes of speciation in the sea are rarely obvious, because geographical barriers are
not conspicuous and dispersal abilities or marine organisms, particularly those of species …

Sulfated fucans and galactans are strongly anionic polysaccharides found in marine
organisms. Their structures vary among species, but their major features are conserved …

REVIEW Although fertilization has been studied for more than a century, the cell surface
proteins mediating the process are only now becoming known. Gamete interaction in …

Behaviors, morphologies, and genetic loci directly involved in reproduction have been
increasingly shown to be polymorphic within populations. Explaining how such variants are …

Bindin is a gamete recognition protein of sea urchins that mediates species-specific
attachment of sperm to an egg-surface receptor during fertilization. Sequences of bindin …

During fertilization, the sea urchin sperm acrosome reaction (AR), an ion channel-regulated
event, is triggered by glycoproteins in egg jelly (EJ). A 210-kD sperm membrane …

▪ Abstract The evolution of proteins involved in reproduction is only now beginning to be
studied. A reoccurring observation is the rapid evolution of the molecules mediating …
