First protocell form Origin of mitochondria Origin of chloroplasts First animals appear Earth's first sea form Precambrian ends A noltesuparrow_forwardResearchers looking for fossils of the earliest life-forms face many hurdles. For example, few sedimentary rocks date back more than 3 billion years. Review what you learned about plate tectonics in Section 16.5. Then, explain why so few remaining samples of these early rocks remain.arrow_forwardWe live in the Cenozoic era, and scientists know more about this era and the epochs it’s divided into than any other time period. Why is this? A. We know more about the Cenozoic era because this is the only era that has had a wide diversity of species living on Earth. B. We know more about the Cenozoic era because this is the most recent time period in the history of the Earth, and we have more information available to study. C. We know more about the Cenozoic era because the planet’s poles reversed magnetic fields at the beginning of this era. D. We know more about the Cenozoic era because fossils don’t exist to document previous eras.arrow_forward
