The Scientific Saga of Dr. Mary Schweitzer

What was the initial reaction of Dr. Mary Schweitzer upon discovering soft tissue in a T. rex bone?

• She dismissed it as contamination.

• She thought it was a mistake.

• She was shocked and surprised.

• She expected it as a common finding.

Which of the following was NOT one of the initial hypotheses about the soft tissue discovery?

• The fossil was a fake.

• The fossil was preserved by a natural mechanism.

• The fossil was contaminated by biofilm.

• The fossil is younger than previously thought.

Why was the hypothesis that the fossil was younger than previously thought considered unlikely?

• The fossil was found in a modern rock layer.

• Radiometric dating confirmed the age of the rocks.

• The fossil was found in a museum.

• The fossil showed signs of recent activity.

What role does iron play in the preservation of soft tissue according to Dr. Schweitzer's findings?

• Iron accelerates decomposition.

• Iron prevents fossilization.

• Iron initiates cross-linking, preserving tissue.

• Iron has no effect on preservation.

What is cross-linking and how does it relate to preservation?

• A process that destroys proteins.

• A process that preserves proteins by binding them.

• A process that creates new proteins.

• A process that removes iron from tissues.

In Dr. Schweitzer's experiment, what was the outcome for the ostrich blood vessels soaked in iron-rich hemoglobin?

• They remained intact for two years.

• They turned into fossilized bones.

• They decomposed in three days.

• They showed signs of bacterial growth.

Why did Dr. Schweitzer choose ostrich bones for her experiment?

• Ostrich bones decompose quickly.

• Ostriches are unrelated to dinosaurs.

• Ostrich bones are similar to dinosaur bones.

• Ostriches are easy to find.

What does Dr. Schweitzer's story exemplify about the scientific method?

• It demonstrates the process of observation, hypothesis, and experimentation.

• It highlights the importance of ignoring critiques.

• It shows that science is based on assumptions.

• It proves that all scientific discoveries are accidental.

What impact has Dr. Schweitzer's discovery had on the field of paleontology?

• It has confirmed that all fossils contain soft tissue.

• It has opened new avenues for understanding ancient life.

• It has led to the dismissal of previous fossil records.

• It has shown that fossils cannot be trusted.

How has the discovery of soft tissue in fossils changed researchers' approach?

• Researchers are actively searching for soft tissue in other fossils.

• Researchers have concluded that all fossils are young.

• Researchers have stopped using radiometric dating.

• Researchers now ignore soft tissue in fossils.
