Organisms with traits well suited to their environment survive and reproduce at a greater rate.

Front

Front

What is the main idea of evolution?

The change in the heritable characteristics of biological populations over successive generations.

Front

What is adaptation in the context of evolution?

A trait that helps an organism survive and reproduce in its environment.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures are similar due to shared ancestry, while analogous structures are similar due to convergent evolution.

Front

What role does mutation play in evolution?

Back

Mutations introduce new genetic variations, which can lead to new traits in a population.

Front

What is the significance of the fossil record in understanding evolution?

Back

It provides evidence of how species have changed over time and shows the existence of extinct species.
