The Figure Shows the Geological History of North and South

question 40

Essay

The figure shows the geological history of North and South America and the closing of the Isthmus of Panama. If a single species was distributed throughout the region indicated by the arrow in the left-most panel, and today is found as two separate species, one in the Atlantic Ocean and one in the Pacific, is this allopatric speciation likely to be an example of the vicariance model or the peripheral isolate model of allopatric speciation? Why?
