Test your knowledge on the consequences of continental drift and allopatric speciation with this quiz. Explore how landmass separation leads to isolated populations and the formation of new species. Discover the diverse frog species in Madagascar, India, and Southeast Asia resulting from continental drift. Put your understanding to the test and see how much you know about speciation caused by the movement of continents.
