What are vestigial organs?

• Organs that perform vital functions in an organism

• Organs that have lost all or most of their original function in the course of evolution

• Organs that are fully functional in one species but not in another

• Organs that are present in adults but not in embryos

Which of the following best describes natural selection?

• The process by which individuals that are better suited to their environment survive and reproduce most successfully

• The process by which all individuals in a species acquire new traits simultaneously

• The process by which individuals learn to adapt to their environment

• The process by which individuals change their behavior to survive

Why is the fossil record important for understanding evolution?

• It shows that Earth is less than 10,000 years old

• It provides direct evidence of organisms that lived in the past

• It shows that all organisms are unrelated

• It disproves the theory of natural selection

What does the presence of homologous structures in different species suggest?

• The species are not related

• The species have a common ancestor

• The species live in the same environment

• The species have the same diet

• They are larger than their functional counterparts

• They have lost their original function through evolution

• They are newly evolved organs
