Imagine that European explorers sailing across the Pacific left several male and female pairs of pigs on a remote island with the intention of visiting again in future years to harvest fresh meat. This would MOST closely resemble a case of artificially induced allopatric speciation through:
A)vicariance.
B)dispersal.

This is an example of dispersal, as the pigs were intentionally transported from their original habitat (Europe) to a new, isolated habitat (the remote island in the Pacific). Artificial selection may eventually lead to divergence in the pig populations on the island, leading to allopatric speciation. However, the initial event that led to their separation was dispersal. Vicariance, on the other hand, would involve a physical barrier separating a population, such as the formation of a new island or a geological event that splits a landmass in two.
