During the 1990s Knowlton and colleagues studied pairsof sister species of the genus Alpheus (snapping shrimp). In eachof these sister species pairs, members of one pair lived on theCaribbean side of the Isthmus of Panama, while members of the otherpair lived on the Pacific side. What type of speciation might beresponsible for this distribution of sister speciesspeciation?
Sympatric speciation
Allopatric speciation with the peripheral isolatemodel
Allopatric speciation with vicariance
Founder effect dispersal based speciation
Autopolyploid speciation
