Earth Science: Geologic History

During which geologic period did humans first appear on Earth?

• Quaternary

• Paleogene

• Triassic

• Permian

Base your answer on the data table below and on your knowledge of Earth science. The data table lists samples of three different materials, the age of each sample, the radioactive isotope used to date each sample, and the location where the sample was found. The iridium-enriched sediment layer was deposited at the end of which geological period

• Permian

• Paleogene

• Quaternary

• Cretaceous
