Part B: Analyze and Extend
Question 1:
Challenges scientists face when classifying a new fossil:
Answer: Scientists face challenges in identifying incomplete or poorly preserved fossils, distinguishing between closely related species, and dealing with variations within a species.
Question 2:
How scientists can use the fossil record to find evidence of relationships between different species:
Answer: By examining similarities and differences in fossilized remains, scientists can trace the evolutionary relationships between species and understand their common ancestors.
Question 3:
Did classifications in part A support the original predictions? Why is understanding the environment of fossilized organisms important to scientific research?
Answer: Yes, classifications generally supported predictions. Understanding the environment is crucial as it provides insights into the ecological context, behavior, and adaptation of the organisms.
Question 4:
Which fossils are most likely heterotrophs? Which are autotrophs? How do you know?
Answer: Fossil A and C are likely heterotrophs as they exhibit features common in animals. Fossil B and D are likely autotrophs as they display characteristics associated with plants.
Question 5:
Why are fossils of hard body parts more common than fossils of other soft tissues or microorganisms?
Answer: Hard body parts like bones, teeth, and shells have a higher chance of preservation due to their durability. Soft tissues and microorganisms decay more rapidly, making them less likely to fossilize.
