Nov 26, 2024 · here, we leverage a “natural experiment” in developmental evolution in sea urchins, where a major life history switch recently evolved in the lineage leading to heliocidaris. In three genera it evolves under positive selection, in four under mostly purifying selection, and in one, results have been mixed. We studied bindin evolution in the pantropical sea urchin. Apr 1, 2004 · in sea urchins, adhesion of sea urchin sperm to eggs and fusion between sperm and egg membranes is controlled by the sperm protein bindin (vacquier and moy 1977; Oct 10, 1999 · in the sea urchin genus echinometra, the protein bindin mediates sperm attachment to eggs, evolves quickly, and is polymorphic within species.
A thorough understanding of sea urchin reproduction.
