Co-evolutionary processes can be studied in particular circumstances when the selective pressure and response trait are readily identifiable and variation in selective pressures is apparent. The coevolution of tetrodotoxin production in prey (newts) and toxin resistance (snakes) has been studied in the western USA. by describing coincident trait variation in a predator-prey system across a geographic mosaic of selective pressure, and linking genotypic and phenotypic variation, the mechanisms of at least one co-evolutionary phenomenon have been revealed.
