Occurrence of endemic species in South America and Australia is due to

1. These species have been extinct from other regions
2. Continental separation
3. There is no terrestrial route to these places
4. Retrogressive evolution

Correct answer: Continental separation

Solution

Endemic species are often found where long-term isolation prevented them from spreading and mixing with other populations. South America and Australia became separated from other landmasses, allowing unique lineages to evolve independently.
