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.

What evidence could be used to convince policy makers to change a shipping lane from going through a whale breeding ground? information on the number of all whale species currently alive information on the number of all whales hit by boats in the given area information on the number of whale deaths in the world's oceans information on the number of whale offspring born every year. (a) scientists could collect and combine data on fish populations all around the world to show that their populations are declining. (b) scientists collect and combine data on fish populations all around the world to show that their populations are increasing. (c) scientists work together and use past data to show that fish populations are becoming locally extinct in some areas. (d) scientists work together and use past data to show that some fish populations are adapting to environmental changes.
