Fossils, Rates & Patterns of Evolution

What is the main reason the fossil record is not complete?

• DNA, homologous structures, vestigial structures, compare bones & Skelton

• not all things that die become a fossil

• Whales are mammals, they have tiny hip bones, there's fossil evidence

• the earth is older than we once though
