Homeostasis is the bodies ability to remain in a stable state or condition. It can be described as a specific state that our body functions best at. Conditions like those that the Zulu and Andean Indian populations experience can take the body out of homeostasis. It is important to find a way to adapt to these challenges and return the body to a stable state, below we will take a look into how homeostasis can be found through adaptation.
Tribe A: Zulu-
Environment: The Zulu tribe is located in the KwaZulu-Natal region of modern South Africa. The temperature ranges, with the coldest months being the middle of the year. The mean temperature for April through September are in the low to mid 60s. A season of rain begins usually around November and goes until February. The hottest months occur from October to May with December-February being their summer months. As far as climate variation, I would say there aren't too many distinct seasons however, the temperatures do rise and fall (“Climate & Weather Averages in Zululand, South Africa”) Conditions that may cause stress include cold or hot temperatures, as well as heavy rainfall this can lead to the body to move out of homeostasis.
Physical Adaptation: Due to their location and its proximity to the equator the Zulu population experience lots of sunlight. A physical adaptation that occurs due to this exposure to sunlight is darker skin tones by UV radiation. Due to the extreme heat they attempt to remain as cool as they can, this is present through their clothing. They tend to wear less clothing further exposing their skin to UV radiation (Tod et al.). Attempting to remain cool in a climate of extreme heat can help the population maintain homeostasis, but a bad sunburn can take the body out of homeostasis.

Cultural Adaptation: One cultural adaptation of the Zulu population includes stick fighting which for the Zulu people is a traditional way to settle disputes, mark one's dominance and occasionally to impress the family of a potential bride. Zulu stick fighting is a part of their history and is very important to the culture. It has been passed down through generations, marking its importance as most boys begin preparing and training for this as children (Administrator). Zulu stick fighting is a signature for the people, that is why I label it as a major cultural adaptation. This may be an activity that helps this population maintain homeostasis as they continue a cultural tradition.

Race: If I was to choose one race to describe the Zulu population I would describe them as Black African. Using the term black can be very broad, as a race I would identify them to be black however, they do originate in the country of Africa. Therefore, the best description I have as far as race for the Zulu Population would be Black African (“Zulu - Introduction, Location, Language, Folklore, Religion, Major Holidays, Rites of Passage”).
Tribe B: Andean Indians-
Environment: The Andean Indians live in a high altitude environment. This can make everyday tasks more difficult due to the shortage of oxygen. The climate is very cold which can lead to challenges like plants freezing and less access to water. The high altitude will cause lots of stress on the body, making it hard to survive in conditions where oxygen is limited. This can result in the body not beginning to maintain homeostasis.
Physical Adaptation: One physical adaptation for the Andean Indians is their high altitude which makes the people adapt to lower levels of oxygen. Recent studies indicate that Andean Indians have larger lung volumes to account for the high altitude. There is also reason to believe that genetic adaptation has occurred making it easier for Andean Indians to live in these conditions (Julian and Moore). This type of physical adaptation helps maintain homeostasis as it can help reduce stress if it is easier for them to breathe.

Cultural Adaptation: Cultural adaptation of the Andean Indians include how they have adapted agriculturally. Through the use of newer technology and learning how to maintain crops in a higher altitude climate (“Andean Agriculture| Globally Important Agricultural Heritage Systems | Food and Agriculture Organization of the United Nations”). This adaptation is important to the culture as it helps the strive as a whole. This adaptation can help them maintain homeostasis as they are able to be successful in agriculture which may lead to the feeling of securement in that area, reducing stress.

Race: Following information I gathered on the Andean Indians, describing them into a category of one race was difficult. I learned they came from a vast number of different locations and were very diverse (“Central Andean Indians”). If I were to choose one race that best fit a description of the Andean Indian population I would use Indigenous.
Summary-Adaptation vs. Race:
When reflecting on physical and cultural adaptation vs. race I think the proper way to describe a culture would be using summary-adaptation. I think describing a culture based on appearance alone can be harmful, but explaining their traditions and how they adapt to their climate can help someone understand the population and what they value. I think that summary-adaptation has more explanatory power as it allows for understanding and for people to ask questions. Whereas using race as a description is minimal information to what the culture is all about. For anthropologists I think they would agree it would be best to use a summary-adaptation approach to explaining populations.
