What is the name of the pigment found in skin? Describe where melanin is found in the skin. What is the difference between a melanocyte and melanin? How does melanin help to determine a person’s skin color? What are the two different types of melanin, and how do they affect the appearance of a person’s skin color? What is an adaptation? Why do species adapt over time? What is a fitness advantage? Give an example of an adaptation that could be seen in a fly that could give it an advantage. Would you expect a person who is a native of Greenland (a country above the Atlantic Ocean, close to the Arctic Circle) to have more eumelanin or more pheomelanin? Why? What is one possible explanation for why humans from different regions of the world have different skin colors? What evidence is there to support the idea that species evolve over time? Explain how the birds in the Galapagos Islands can be evidence for this theory. Imagine a scientist wants to study why people who are indigenous (native) to Australia have dark skin. What type of data would you suggest that they collect? What risks are there for a native Ethiopian moving to the Netherlands (a country in northern Europe)? What nutrient deficiencies could they suffer from? What risks are there for a native French person moving to Panama (a Central American country near the Equator)? What nutrient deficiencies could they suffer from? What other diseases could they be at higher risk of? When it comes to risk of skin cancer, why is a person with more melanin at an advantage over people with lighter skin colors? Explain what is happening in their cells that puts them at an advantage.
