Evidence

How is the Cambrian Explosion inconsistent with macroevolution?

• New types of body plans showed up gradually.

• New types of body plans showed up suddenly.

• Changes appeared suddenly, all at once.

• Changes appeared gradually throughout the layers.

• All of the above

What is true about morphological intermediates?

• They are organisms that share characteristics with different animal groups.

• There are many examples in the fossil record.

• Macroevolution predicts their appearance in abundance in the fossil record

• All of the above

• Archaeopteryx was thought to be a morphological intermediate between dinosaurs and birds.

Give one piece of evidence from the eruption of Mount St. Helens that shows that geologic processes can occur rapidly.

• Rock layers formed quickly from ash and sediment.

• The decay rate was always constant.

• There are millions of fossils.

• Many animals were buried in ash.

Which of these statements are assumptions that must be true for radiologic dating to be accurate?

• The rock has interacted chemically with only certain other rocks.

• The decay rate is always constant.

• The rock being tested hasn't had any chemical exchange with rocks around it.

• The beginning amount of daughter product is variable.

• Mother-to-daughter ratios were only affected by radioactive decay.

Which evidence is inconsistent with the geologic time scale of millions of years.

• Erosion and sedimentation in the ocean.

• Bedding layers of sedimentary rock.

• Flat gaps

• There are large rock layers across big areas.

• Marine fossils are found on the continents.

Which are evidence of a world-wide flood?

• Millions of fossils

• Widespread sedimentary deposits

• Marine fossils are found on the continents.

• Sedimentary layers laid down by water all across the continent.

• All of the above

What is true about morphological intermediates?

• They are organisms that share characteristics with different animal groups.

• There are few examples in the fossil record.

• Macroevolution predicts they won't appear in the fossil record

• All of the above

Which of these statements are assumptions that must be true for radiologic dating to be accurate?

• Half-lives can change.

• The decay rate is always constant.

• The rock being tested hasn't had any chemical exchange with rocks around it.

• The beginning amount of daughter product is known.

• Radioactive ratios were affected by things besides decay.

Which evidence is inconsistent with the geologic time scale of millions of years.

• Erosion and sedimentation in the ocean.

• Slowly formed layers.

• Flat gaps are eroded away.

• There are large individual rock layers across big areas.

• Marine fossils are found on the continents.

Which are evidence of a world-wide flood?

• Millions of fossils

• Only a few sedimentary deposits

• Marine fossils are found in the ocean.

• Sedimentary layers laid down by water all across the continent.
