Core B, Unit F, Evolution Blog 1

This week we begin our study of evolution or how species have adapted and become more complex over time. We will focus our attentions on fossils and fossil evidence for this blog.

Typical Fossil's found in ancient oceans. These fossils are known as Trilobites.  Trilobites are animal like mollusks that lived in the ocean, had a hard shell. 

Use the link below to watch the movie and then answer the questions in complete thoughts.

Analysis Questions: (5 points)

1. List the first 3 time periods in which dinosaurs lived from youngest to oldest.

2. What information is missing from the fossil record?

3. Give a possible explanation for why dinosaurs grew in size over time.

4. What characteristics would you expect to find in a mammal like reptile that would enhance its chances of survival over a plain reptile?

5. Why do you think this would be considered a transitional species?

Extended Response Question (16 points)

After watching both videos on whale evolution, respond to the following question.

1.Explain why the modern whales ancestor moved from land to water and provide evidence to support your explanation.

2.Describe the physical changes that took place over time that made the modern whale a water dweller and  Explain how these changes would be considered adaptations to the new environment.

3. Compare the challenges that faced the modern whale as it evolved over time.

4. Describe how the whale survived over time when confronted by predators.

The Cheetah Problem!

---

     

  

This Chart shows the predicted decline in cheetah population throughout the world. Currently, there are roughly 10,000 cheetahs in Africa and Asia.  The likely extinction of the viable cheetah population is sometime around 2015-2025.  Viability is the key word. A population becomes genetically non viable when the population drops to below 12,000.   It would seem likely that the species will survive but only in limited surroundings, provided captive breeding goes well. The problem of the endangered cheetah is quite complex but the underlying problem is really about human population growth and expansion.

 http://www1.american.edu/ted/cheetah.htm

this BLOG is worth 20 points!

1.       List the 3 main issues that endanger the cheetah population.

2.      How are the cheetah and wolf similar in nature?

3.       How did the ice age affect the cheetah population?

4.      How did this major climate event create a genetic “bottleneck” for the current cheetah population?

5.      Explain how the physical features of cheetahs make them exceptional predators.

6.      What factor could potentially kill off all the cheetahs very quickly?

7.       Describe 3 ways humans have reduced the cheetah population.
