- High levels of solar radiation. This has negatively impacted the survival of humans because if not properly equipped to tolerate the radiation, it can cause illness and death.

- The benefits of studying human variation over environmental clines is that it gives a greater understanding to the origin of variations. How the variation began, and why it changed.
- Looking at race to explain the variation to high levels of radiation does not paint a clear picture. As race is the product of this environmental cline, not the other way around.
This was a short on content and explanation. In particular, the second section needed expansion explaining how each adaptation helped address the chosen stress.
ReplyDeleteFor your opening section, how does solar radiation cause "illness and death"?
Short term: Sunburn is not an adaptation. It is an indicator that the body has failed to adapt to the stress. Remember that an adaptation will help the organism, not hurt it.
Facultative: How does tanning help address solar radiation?
Developmental: What does "dark photo-protective pigmentation" mean? Do all humans develop this to the same extent? Why or why not?
Cultural: Expand.
Okay on section 3.
Race isn't a product of the environment. It is a social construct and subject to individual and cultural bias. That is why it is not useful. How does the adaptive approach avoid this problem?
I like the pictures you used , in particular the Kim one. Is that her sunburn or her dark photo pigmentation ? I thought it was a little short but i understood it . Good job .
