What processes gave rise to the reproductive isolation between Caribbean and Pacific marine organisms on either side of Central America? Discuss both biotic and abiotic processes in your answer
What will be an ideal response?
After the formation of Central America by geological processes the Caribbean and the Pacific became isolated from one another. As a result, different selective processes began to operate in the two regions resulting in populations diverged evolutionarily from one another. Different evolutionary paths led to reproductive isolation between groups that once belonged to the same species.
