Which best supports the idea of continental drift?

Which best explains why species living in Australia are found nowhere else on Earth?

• Australia has an ecosystem different from any other area on Earth.

• Humans have genetically altered many Australian species in laboratories.

• Australian species were genetically altered after a comet hit the landmass.

• Australia separated from other continents and species there evolved independently.

A new type of plant was discovered on a newly-formed volcanic island. The island is hundreds of miles away from the mainland. Which hypothesis best explains how the plant arrived?

• It spontaneously generated.

• It was carried there by humans.

• It was carried there by wind or waves.

• It was already present in volcanic materials.

Two organisms have homologous structures. Which can most likely be concluded about the two organisms?

• They are unrelated.

• They are the same organism.

• They share a common ancestor.

• They evolved in a similar environment.
