Answer:
The correct answer is option d. "Many species that moved into North America from South America outcompeted the endemic taxa and still exist today".
Explanation:
The Great American Biotic Interchange (GABI) was an historical period at which numerous species from South America migrated to North America, and numerous species from North America migrated to South America because of the formation of the Isthmus of Panama. During this event, many species that moved into North America from South America outcompeted the endemic taxa and still exist today. The species that successfully immigrated to South America and exist today were mostly small mammals, such as armadillos and opossums.
The correct answer would be the last one: "evolved from past organisms." This theory basically just states that all living organisms evolved from a single common ancestor. Hope this helped! :)
