Scientists have proposed that speciation occurs when members of a population become reproductively isolated from one another. for example, speciation can occur when a population becomes split by a physical barrier and the two populations come under different selection pressures. recently, fossils of fish have been discovered in sediments on opposite coasts of a large island that arose following a volcanic eruption event. design an experiment to test the hypothesis that speciation occurred in these fish. include a description of your experimental plan, the types of data you will collect, and an explanation of how the data will enable you to determine whether the hypothesis is correct.
