Evidence of Common ancestry Post-assessment

Rocks containing 450 million year old Ordovician fossils contain jawless fish. Younger Devonian rocks that are only 400 million years old contain fossils of jawless fish and fish with jaws. This evidence supports the idea that -

• species can suddenly appear in the fossil record.

• there are large gaps in the fossil record.

• older rocks are found above younger rocks.

• groups of species have changed sequentially.
