The Society for Georgia Archaeology (http://thesga.org) offers this twelve-question quiz that asks you which side of the Atlantic various species were native to immediately prior to the Columbian Exchange. The Columbian Exchange is the name we give to contact between the Old and New World continents by human beings that began with Christopher Columbus's expedition of 1492. The Old World is Europe/Africa/Asia. The New World is the Americas—North, South—and in between.
