The Zulu people generally populate the north eastern region of South Africa, primarily within the KwaZulu-Natal province, bordering the Indian Ocean on their furthermost eastern border, and Mozambique to the north.
Zulu peoples’ primary physical adaptation is dark skin. As the weather is often hot and humid, minimal clothing is worn to aid in temperature regulation. The high concentration of melanin within their skin cells protects their skin from the damage of constant sun exposure and helps maintain the balance of their internal body temperature.
Cultural adaptations can be observed in their housing, attire, and resource management, all working to combat environmental stressors previously mentioned. Traditional Zulu homes are made of local mud and grasses, properly insulating to keep warmth in the night and expel heat during the day. As mentioned above, traditional attire is minimalist, combatting constant sun exposure by keeping the skin cool and avoiding overheating.
Zulu are racially categorized as Black, and of the Bantu ethnolinguistic family. As “black” is a widely used, highly applicable category, the Bantu group narrows the group further based on common cultural and linguistic ancestry within the Niger-Congo family. Even with this narrowing, the Bantu race encompasses hundreds of ethnicities besides Zulu, each sharing similar features of dark skin and round facial features. From an anthropological perspective, it would be more useful to examine the Zulu under the Bantu race as it places them within the very broad context of “black” or “African.”
The indigenous peoples of the Andean Mountain Range live across a number of nations in western South America. While largely within the tropical and equatorial region, the high peaks, lowlands, and Atlantic and Pacific coastal regions offer tons of variability in climate. On average, the lowlands are hot, particularly dry, and humid near the coasts, while the mountainous peaks are icy and the air is especially thin given the high altitude. Rain varies based on altitude and location; the inner regions experience the most precipitation, measurable rainfall dwindling as you move outwards towards the coastal deserts. Additionally, annual rainfall and average temperatures are dependent on the cyclical El Niño and La Niña weather phenomena. The warmest portions of the mountain range typically rest around high 70s on summer days, and nights are cold across the range all year. The eastern region known as the Amazon basin houses torrential rain and frequent flooding. Environmental stressors like limited oxygen, temperature extremes, and intense sun exposure put the Andean people in a position to be out of homeostasis.
These highlanders are proved to have physical adaptations to combat the high altitudes and sun exposure. Indigenous Andeans have increased lung capacities and higher hemoglobin levels, both of which allows greater oxygen per breath and improve the flow throughout the body, ultimately preventing hypoxia. These are genetic adaptations of the utmost importance as the high altitudes greatly affect how much oxygen is available and how the human body utilizes it. Andean complexions also aid in preventing sun damage while maintaining sufficient levels of vitamin D. Given the equatorial location and intense exposure on the mountain peaks, Andeans had to biologically adapt to the sun exposure as is it often too cold to dress minimally as seen in the Zulu people.
Andeans have also learned to combat geographical challenges against farming. By learning to cultivate resilient crops tolerant to poor soil quality, drought and frost alike. Terrace farming allows the people to work within their environment rather than fight the mountains or have to move away. Generations have learned to observe the sky to predict rainfall and make the most of their harvests.
Indigenous Andeans are categorically considered Native American, as their cultures and genetic landscapes developed before the Columbus era. There is also quite a bit of nuance in considering these people, as the Inquisition introduced many Spaniard features and genes into the region, but the Andeans do not traditionally speak Spanish or fit the “white” category many other Latin cultures get placed into. Native American is likely the most appropriate race given the tan to dark skin, dark straight hair, and prominent bone structure shared with other indigenous Americans.
