Adaptive divergence

The transcript discusses how species evolve from a common ancestor by adapting to different environments, leading to the formation of new species over generations. It highlights Darwin's observation of finches in the Galapagos Islands, where species evolved due to isolation and adaptation to local conditions and food sources.

What is the result of species adapting to different environments over many generations?

• They lose their ability to adapt.

• They become extinct.

• They form new species.

• They remain unchanged.

What did Darwin observe about the finches in the Galapagos Islands?

• They were not related to each other.

• They could not survive on the islands.

• They had adapted to different environments.

• They were all identical.

How did the finches on different islands evolve according to Darwin?

• By migrating frequently between islands.

• By adapting to local conditions and food sources.

• By remaining isolated from each other.

• By competing with each other for resources.

What role does isolation play in the evolution of species?

• It prevents species from adapting.

• It leads to the extinction of species.

• It allows species to adapt to specific environments.

• It causes species to become identical.

Why is the Galapagos finches' example significant in understanding evolution?

• It shows that species cannot adapt to new environments.

• It demonstrates the role of isolation in species adaptation.

• It proves that all species are identical.

• It indicates that species do not change over time.
