How do homologous structures in different species support the idea of a common ancestor?

• They have exactly the same function in all species

• They have similar basic structures despite different functions

• They always look identical in all species

• They only exist in closely related species

Which of the following best explains why scientists use a classification system for organisms?

• To determine which animals are the most intelligent

• To group organisms based on shared characteristics

• To decide which species are most important to humans

• To calculate how many species exist on Earth

How does the fossil record contribute to our understanding of evolution?

• It shows us what dinosaurs looked like in color

• It provides evidence of how organisms have changed over time

• It tells us exactly when each species appeared

• It proves that evolution happens quickly

Which of the following is NOT a level in the hierarchical classification system?

• Kingdom

• Phylum

• Ecosystem

• Species

What is the main difference between homologous and analogous structures?

• Homologous structures have the same function, while analogous structures look similar

• Homologous structures have a shared ancestry, while analogous structures evolved independently

• Homologous structures only occur in mammals, while analogous structures occur in all animals

• There is no difference; the terms are interchangeable
