Textbook Question
Chapter 13, Problem 9TYK
In the late 1700s, machines that could blast through rock to build roads and railways were invented, exposing deep layers of rocks. How would you expect this development to aid the science of paleontology?

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. Which of the following statements can be…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

After the dinosaurs became extinct, the small mammals that had been relatively unimportant animals in the background flourished and evolved into many new types, including the line that led to human beings. It is unlikely that these new types would have ever evolved had not the dinosaurs disappeared. If the extinction of the dinosaurs was caused by an extraterrestrial impact, did it matter how well they were adapted to their environment? What does this suggest about the starting cause in the evolutionary success of these new types of mammals?arrow_forwardWhich is a difference between a forensic anthropologist and a bioarcheologist? a forensic anthropologist looks at the whole crime scene where the bioarcheologist only looks at the skeletal remains a forensic anthropologist builds a biological profile and a bioarcheologist looks at grave goods a forensic anthropologist looks at modern humans and a bioarcheologist looks at fossil hominins a forensic anthropologist works on recent cases where a bioarcheologist looks at sites deep in the pastarrow_forward

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.
