The Isthmus of Panama began to appear around 10 million years ago, and completely connected North and South America by 3 million years ago, which divided the Caribbean and Pacific oceans. An original 15 snapping shrimp species are hypothesized to have become 30 different species after being split into separate populations by the Isthmus of Panama. What kind of speciation is most likely to have caused this increase in snapping shrimp species around the Isthmus of Panama?
A. Parapatric speciation
B. Temporal speciation
C. Sympatric speciation
D. Allopatric speciation
