Introduction
As we continue to navigate the Earth Through Time of our Evolutionary History unit, you will continue to explore concepts such as evolution and the significance of fossil evidence.
After watching **each** video, open this forced Google Document to answer EACH/ALL of the questions in the "Task" section below.
You will then ADD the 1-page write-up in the "Evaluation" section to the Google Doc you created. Then the final/completed Google Doc will be uploaded to the assignment in Google Classroom.
Task
Task 1: Watch the video published by PBS entitled, " Fossils: Rocking the Earth" and respond to the following questions :
1) What are fossils?
2) Why are fossils significant? How do they assist scientist?
Task 2: Homologous Structures
1) Homologous structures are structures that have similar structure but different functions.
A) True
B) False
2) Homologous structures suggest that many species are related and have common ancestry.
A) True
B) False
3) Over time, species change. Once a species changes so much that it cannot reproduce with the older species a new species has developed. Meaning, older and newer species eventually are considered to be two different species because they can no longer reproduce together.
A) True
B) False
Task 3: Vestigial Structures
1) Explain what are vestigial structures.
Task 4: The Spinosaurus
Task 5:
Explore the following links to learn more about fossils
National Geographic :
https://www.nationalgeographic.org/encyclopedia/fossil/
Science News for Students :
Evaluation
Great Job! Now that you have familiarized yourself fossils and the evidence they leave behind ... NOW, Construct a 1 page explanation detailing the following (can be added to your current Google Document):
A) The importance of fossils
B) The role they play in evolutionary history
C) Explain how anatomical similarities and differences among species ( past and present) suggest they are related
