Why is the unique wildlife of the Galápagos Islands explained by their volcanic origin and isolation?
Why is the unique wildlife of the Galápagos Islands explained by their volcanic origin and isolation?
- Due to the presence of similar fossil species on the islands
- Volcanic origin and isolation influence the evolution of endemic species (correct)
- Because the islands have a high population density of organisms
- As a result of continental drift separating the islands from the mainland

How do the forelimbs of humans, whales, bats, and birds demonstrate evolution?
How do the forelimbs of humans, whales, bats, and birds demonstrate evolution?
