South Africa and Andes Mountains

ZULU

I consider the people to be African due to their darker skin tone contributed by the hotter climate and UV rays.The 9 million Zulu-speaking people live mainly in KwaZulu-Natal Province of South Africa. The subtropical climate brings lots of sunshine and brief, intense rain showers.

Durban boasts an average of 320 days of sunshine a year. Temperatures range from 16 to 25º C in winter. During the summer months the temperature ranges from 23 to 33º C between, September and April. January is generally Durban’s hottest month, with an average daily temperature of +/- 32ºC. The warm Mozambique current flowing along the coast means wonderfully warm bathing throughout the year, the water seldom falling below 17º C even in the middle of winter.There are many people and animals killed annually by lightning, thus the fear.

During periods of increased rainfall, the carrying capacity of the land also increases and this allows for the population to increase; again this develops a momentum as increases are cumulative. Then, when the cycle turns and becomes drier, the population is too large for the lower carrying capacity of the land. The growing competition for the dwindling resources leads to rapid and escalating resort to military means. The winner is that group which developed the strongest and best military machine. Those in Southern Africa still experience food shortages due to the sub-Saharan conditions that exist in this region. Climate changes have also become more important and made a difference in the way the climate impacts where people live in Southern Africa.

ANDEAN

I would consider the population to be Indian by their skin color and dark long hair. The precipitation of the Andes Mountain climate changes but not drastically between two places. In Colombia there is a lot of rainfall all year round. In Ecuador there is the desert climate without much rainfall. Peru is similar to Ecuador. In Chile there are two different climates but in both there is a sufficient rainfall all year round. The rain fall in the summer averages less than 8 in. In the winter it averages less than 4 in. These numbers are from biomes in and around the Andes Mountains.

First, there is the alternating daily extreme of climates that often range from hot, sun burning days to freezing nights.  In addition, winds are often strong and humidity low, resulting in rapid dehydration.  Second, the air pressure is lower.  This is usually the most significant limiting factor in high mountain regions.

The primary solution of Indians from the high mountain valleys produce more hemoglobin and the checks will be red due to increased blood flow and more red blood cells.

The higher the altitude, the lower the temperature, the coastal lowlands, the lower western Andean slopes, and the Orient generally have a warm, tropical climate. The climate grows much cooler in the highland valleys. Above 12,000 feet (3,700 meters) it is continually cold and the higher Andean peaks are snow-covered all year long. Rainfall is heaviest in the Orient, which may receive 100 inches (2,500 millimeters) or more of rain a year.

I think for both groups physical appearance is a bit easier to categorize the populations based upon outward appearance. I think you can tell someone is feeling, healthy by their physical appearance. But I think for a anthropologist physical and cultural adaptations will let them know why the people of that area look a certain way, diet, climate, water and skin.
