Answer Key with Extended Explanations
1. C – Biogeography studies how species are distributed across the planet and how that distribution relates to evolution.
2. C – Evolutionary biology uses biogeographical patterns to trace lineage and adaptation.
3. C – The separation of continents explains the distribution of similar flightless birds that share a common ancestor.
4. C – Plate tectonics/continental drift greatly affected where species evolved and spread.
5. C – An endemic species is one that’s found in a specific, limited location.
6. B – The Galápagos tortoise is native only to the Galápagos Islands, making it endemic.
7. A – Continental drift describes the movement of Earth’s tectonic plates over millions of years.
8. C – The presence of similar but distinct species on different continents supports the idea of common ancestry followed by geographic isolation.
9. E – Most marsupials, like kangaroos and koalas, are found in Australia.
10. C – Species on separated continents often evolved from common ancestors before the landmasses drifted apart.
11. C – Island biogeography theory suggests that species diversity depends on island size and its distance from the mainland.
12. C – Dispersal refers to organisms moving from their place of origin to new areas.
13. B – Vicariance occurs when physical barriers like mountains or oceans split populations.
14. C – The breakup of supercontinents like Pangaea caused vicariance, isolating populations.
15. C – Islands develop unique species because of their geographic isolation, which limits gene flow.
16. D – Convergent evolution occurs when different species evolve similar traits due to similar environmental pressures.
17. B – Though unrelated, whales (mammals) and fish (not mammals) have streamlined bodies due to aquatic environments—convergent evolution.
18. C – The same species’ fossils on different continents show those lands were once joined.
19. C – The Amazon is one of the most biodiverse regions on Earth.
20. C – Biogeography supports evolution by showing how similar environments produce similar adaptations in unrelated species.
