Question

Researchers discovered a species of termites that inhabited a small woodland area. A few years later they returned to find that a small population of these termites varied slightly from the others and could no longer interbreed wtih the original type. this is an example of what?

a.) polypoidy
b.) sympatric speciation

You know it is speciation because the two populations can no longer interbreed; it is sympatric (same country) because they live in the same area.
