Which of the following periods is the earliest during which animals may have appeared? a. Ordovician period b. Cambrian period c. Ediacaran period d. Cryogenian period
There was a large proliferation of fossils showing increase in diversity of life.What period is this?
A construction project required digging hundreds of feet into the ground, which exposed many discrete strata. After a thorough investigation, paleontologists do not find fossils of Tiktaalik or any similar species. Explain why this finding could not be used to refute the theory of evolution.

Which statement would a scientist most likely offer to explain this situation? A.) The fish in the lower layer lived in the deep sea. While the other fish lived in shallow water. B.) The fish in the upper layer lived a healthier life than the other fish. C.) The rock in the lower layer is denser than the rock in the upper layer D.) The rock in the upper layer must have formed in freshwater E.) The fish in the upper layer lived more recently than the other fish. The Geologic Time Scale is a systematic chronological dating process that relates geological strata to time. This methodology is commonly used be geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that once occurred in history.

- We 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_forwardFrom the early 1700s to the modern day, how did various lines of evidence clarify and improve scientists' understanding about the ancestry of cetaceans?

- Why is it so important to learn about the Piltdown Hoax? Do you think it demonstrates that scientists may lose their objectivity when they want data to fulfill their expectations and desires or does it demonstrate the self-corrective nature of science?

He believes that the fossil is around 12,000 years old. Which method would best allow the scientist to confirm the actual age of the fossil? finding another fossil in a deeper layer of rock finding another fossil in the same layer of rock using carbon/nitrogen absolute dating using potassium/argon absolute datingarrow_forwardIt has been suggested that the current time should be made into a different period. In other words, it should not have been part of the Holocene period due to the extreme changes man has made to the earth.
