Zulu:
1. The Zulu tribe lives in the KwaZulu-Natal Province of South Africa. They live in a subtropical climate that is the cause of sun and sometimes intense rain. They have sunny conditions most of the year round. Almost 330 days of sunlight which leaves little days without.
2. The physical adaptation would be their skin color, the dark color of their skin would help them with their intense heat. With more color in their skin it helps block out UV rays, protecting them from the sun.
3. The cultural adaptation is their rondavels or their houses, they are made of mud, grass or iron sheets. They also provide protection from the sun’s heat and shelter.
4. The Zulu tribe is of African race.
Andean Indians:
1. The Andean Indians live in the Andes range in South America, stretching from Ecuador to Peru to Chile. Their weather is very tropical, hot and humid.
2. A physical adaptation they developed is their lungs, they tend to be larger to better suit the high altitude in which they live.
3. For the Andean Indians the cultural adaptation they created to help support their food source is irrigation systems, and even terraces. It would be hard to grow food in that area without the proper watering
4. The race of the Andean Indians is Hispanic, since they come from South America.
Part 5.
It is much better to approach describing populations through their adaptations more than their race. Race does not tell you much, it just tells you the color of their skin. It would be more useful to anthropologists to look at adaptations to understand why culture look and do the things that they do. Race is not very explanatory, while adaptations can tell you why people have larger chests in the Adeas Mountains because they need the extra space for air, or that the people of Africa tend to have darker skin to help them against the harsh sun.
