What are pseudogenes?

• cell structures that function like genes

• gene sequences that no longer function

• protein sequences that look like genes

Evolution is considered to be one of the most important theories in science, because it

• was developed more than 100 years ago.

• is not supported by the fossil record.

• unites the fields of biology, geology, chemistry, and ecology.
