A grasshopper species lives in a temperate grassland.Along the southern edge of the grasshopper's range, drought over several years changes the habitat into a semi-desert.A large population of the grasshopper in this region separates from the rest of the population, moves farther south, and eventually becomes a new species, much better adapted to arid conditions.This instance of speciation apparently resulted from which evolutionary process?
A) Dispersal
B) Vicariance
C) Genetic drift
D) Continental drift
E) Climate change
