Searching For Candidate Speciation Genes Using A Proteomic Approach: Seminal Proteins In Field Crickets

For decades, evolutionary biologists have sought to discern the types of genetic changes that lead to the creation of new species. To date, very few “speciation genes” have been identified. These “speciation genes” help to create and preserve species boundaries by preventing the production of hybrids. Genes controlling fertilization are likely candidates. Some male ejaculate proteins affect female reproductive physiology and behavior.
