Evidence for Evolution Quiz

What is the main idea of the article?

• Living things adapt over time to their environments

• Fossils give strong evidence of evolution

• Evolution is when parents pass on traits to their children

• Evolution is a recent discovery

What is the fossil record?

• A record of the remains of modern animals

• A record of the age of fossils

• A story of the past showing the evolution of form over millions of years

• A record of all the fossils found in the world

What are homologous structures?

• Structures that have no clear function and appear to be remaining parts from a past ancestor

• Structures that are present in living things but have not been lost

• Structures that share the same simple form and come from a shared ancestor

• Structures that show convergence of form in living things

What are vestigial structures?

• Structures that show convergence of form in living things

• Structures that are present in living things but have not been lost

• Structures that share the same simple form and come from a shared ancestor

• Structures that have no clear function and appear to be remaining parts from a past ancestor

What is an analogous structure?

• Structures that share the same simple form and come from a shared ancestor

• Structures that have no clear function and appear to be remaining parts from a past ancestor

• Structures that show convergence of form in living things

• Structures that are present in living things but have not been lost

What is the similarity between homologous and analogous structures?

• They both share the same simple form and come from a shared ancestor

• They both have no clear function and appear to be remaining parts from a past ancestor

• They both show convergence of form in living things

• They both have a surface-level similarity because they are adaptations to similar environments

What is the difference between homologous and analogous traits?

• Homologous traits share an evolutionary path that led to the making of that trait, while analogous traits do not share that path

• Homologous traits are present in living things but have not been lost, while analogous traits share the same simple form and come from a shared ancestor

• Homologous traits have no clear function and appear to be remaining parts from a past ancestor, while analogous traits show convergence of form in living things

• Homologous traits share the same simple form and come from a shared ancestor, while analogous traits are present in living things but have not been lost

What is the main difference between chimpanzees and humans despite sharing 99% of their genes?

• The relative lengths of their arms and legs

• The shape of their fins

• The shape of their tails

• The shape of their wings
