Hello Emma,



This is not a question that can be answered completely in a couple of paragraphs, mainly because there are still studies being done, and also, anthropological information is pretty detailed. One piece of interesting information is that people who have wider noses, for example some Africans and Asians, lived in a hot, dry, environment. This larger nasal cavity was effective in moisturizing the inhaled air, and precipitating moisture on the nasal membranes when they exhale. This would have been important to prevent water loss and consequently, dehydration. Additionally Africans lived in an environment with high levels of UV radiation, if they had low melanin in their skin (lighter skinned) then the UV levels would allow the radiation to reach subepidermal tissues. So in reaction to this, melanization (increase in the density of melanocytes in the epidermis and the production of darker skin) would occur to protect them.

Facial structure, like cheeks can be determined by whether your ancestors were meat eaters or not. Meat eaters tended to have larger cheek and jawbones. Almost everything on your face from your lips, jaws, eyes, cheeks, neck, skin color, etc is a direct result of the persons ancestral environment. Our bodies knew then and now how to evolve to suit our needs.

What are the differences between races and how did they evolve
