Skin Deep Human evolution and skin color

It's all about Vitamins


1. Why did humans evolve dark skin pigmentation?

2. What are the risks associated with being folate depleted?

3. How does the risk of being folate depleted relate to the process of natural selection for human skin color?

4.Why don't other primates living near the equator (gorillas, chimpanzees) have dark skin pigmentation?

5. Why did humans evolve low (think light skin) skin pigmentation?

6. What are the risks of being Vitamin D deficient?

7. How does being Vitamin D deficient relate to the process of natural selection for human skin color?

7. At what latitude can humans no longer produce enough Vitamin D regardless of skin color?

8. How come humans can now live above this Vitamin D latitudes regardless of skin color?

Predator Prey Lab Analysis Questions

Discussion Section: Round 1 (Deer Only)

1. Did the class data fully support your hypothesis regarding the effect of having no predators on the deer population? Did it disprove your hypothesis? Did it support your hypothesis but with certain exceptions? (1-2 sentences)

2. What specific data from your lab led you to support or reject your hypothesis? Refer to your graphs as evidence to support your judgment regarding your hypothesis. (1 paragraph)

3. Use your understanding of community ecology to explain why the results did/did not support your hypothesis. If your hypothesis was disproved, how has your understanding of community ecology changed? (1 paragraph)

4. What were the limitations of our model (simulation) for round 1? What impact do these limitations have on the data? (1 paragraph)

Discussion Section: Round 2 (Deer and Wolves)

1. Did the class data fully support your hypothesis regarding the effect of having predators on the deer population and the wolf population? Did it disprove your hypothesis? Did it support your hypothesis but with certain exceptions? (1-2 sentences)

2. What specific data from your lab led you to support or reject your hypothesis? Refer to your graphs as evidence to support your judgment regarding your hypothesis. (1 paragraph)

3. Use your understanding of community ecology to explain why the results did/did not support your hypothesis. If your hypothesis was disproved, how has your understanding of community ecology changed? (1 paragraph)

4. What were the limitations of our model (simulation) for round 2? What impact do these limitations have on the data? (1 paragraph)

Discussion Section: Round 3 (Deer, Wolves, and Hunters)

1. Did the class data fully support your hypothesis regarding the effect of human hunters on the deer population and the wolf population? Did it disprove your hypothesis? Did it support your hypothesis but with certain exceptions? (1-2 sentences)

2. What specific data from your lab led you to support or reject your hypothesis? Refer to your graphs as evidence to support your judgment regarding your hypothesis. (1 paragraph)

3. Use your understanding of community ecology to explain why the results did/did not support your hypothesis. If your hypothesis was disproved, how has your understanding of community ecology changed? (1 paragraph)

4. What were the limitations of our model (simulation) for round 3? What impact do these limitations have on the data? (1 paragraph)

Predator Prey Lab Class Data

Use your class data to graph all three rounds.

1 round per graph

Round 1 Deer only (one line)
Round 2 Deer and Wolves ( two lines)  *if you are really thinking you will use 2 vertical axis scales
Round 3 Deer, Wolves and Hunters (two lines) * if you are really thinking you will use 2 vertical axis scales


Period 1 Class Data

Period 3 Class Data

Writing the results section

Use lab write to guide the writing of the results section of your lab


Use the remainder of the period to write the results section of your lab.  Upon completion ask a member of your lab group to review your results section using this rubric.



Visualizing the data from the video game lab

Upon completion of the testing  please do the following

1. Make sure all members of your lab group have entered their data
2.Graph the data collected from your group
3. Graph the class data



If you need help creating the graphs please go to labwrite.




5. Visualizing the data:

Now that you have entered your data in a table or spreadsheet, you are ready to represent your data in the appropriate visual format for your lab report.
  • Establish what types of data you have, quantitative or qualitative (refer to the Resources page in the web version of this document; once there, choose "Data Types").
  • Determine if the data should be represented as a table or a graph (refer to the Resources page in the web version of this document; once there, choose "Tables vs. Graphs").
  • If you decide to use a graph to represent your data, determine which type of graph is one that best represents your data (refer to the Resources page in the web version of this document; once there, choose "Graph Types").
  • If a table is the best format for your data, then modify the table you used to collect your data so that it is labeled and organized properly (refer to the Resources page in the web version of this document; once there, choose "Designing Tables").
  • If you need help creating a spreadsheet to make a table or graph, refer to the Resources page in the web version of this document. Once there, choose "Excel Tutorial."
  • Remember that the purpose of your table or graph is to summarize your findings for yourself and for others and to reveal trends in your data.

Meiosis review questions


1.     Explain how meiosis differs from mitosis.
2.     Why meiosis is called reduction division? What is being reduced? What is being divided?
3.     A) What is synapsis? B) Draw a tetrad. C) Draw a crossing over using different colors. D) during what stage synapsis occur?
4.     Why from an evolutionary perspective synapsis make sense?
5.     Explain the advantage of meiosis during sexual reproduction over mitosis during asexual reproduction from an evolutionary perspective.
6.     Why is important that sex cells are haploid? Explain why the accuracy of meiosis play a major role in the survival of a child and give an example of what happens when there is a mistake in meiosis? Use a human life cycle as an example.
7.     Diagram and label what is happening at each stage of meiosis. Use 4 homologue pairs.
