7．Have you ever wondered why there are so many skin colours in the world？Do you know why people living in particular areas usually have a certain colour？Biology and history are the two reasons for this．
Skin contains something called melanin，which determines a person's skin colour．The more melanin a person has，the darker his or her skin will be．The amount of and production of melanin are controlled by genes，but can be affected by other things，such as sunlight．If a person lives in a place with strong sunlight，his or her skin will protect itself by producing more melanin，making the skin darker．In a place with less sunlight，a person's body will produce less melanin，making the skin lighter．
Skin colour is also affected by another source-vitamin D．Humans all need vitamin D to build bones．People can get it by eating foods such as fish and milk，or from sunlight，which causes vitamin production in the skin．Melanin protects skin by absorbing sunlight，so sunlight absorbed by melanin cannot be used for vitamin D production．Therefore，a dark-skinned person will produce less vitamin D than a light-skinned person when they receive the same amount of sunlight．
The connection between vitamin D production and skin colour is clear when we look at evolution．The earliest humans lived in Africa，their dark skin covered with hair．When they moved to places that had less sunlight，their bodies produced less vitamin D because of their dark skin．As a result，their skin made less melanin，so they could get enough sunlight to produce vitamin D．Their skin gradually got lighter and they lost hair．Now，people who live in areas with strong sunlight，like Africa，have darker skin，while people living in other areas have lighter skin．The exception to this is the Inuit，who live in a place with little sunlight，but have dark skin because they eat a lot of fish and have enough vitamin D．
Evolution has given us a rainbow of skin colours．Humans have always had melanin to determine our skin colour．What has changed through history is the environment where we have lived．This has in turn changed our melanin production，and eventually，skin colour．

A World of Skin Colour
| Brief introduction | People living in a particular area usually have the （71）sameskin colour and there are many different skin colours in the world． |
| Reasons for skin colour | The reasons for different skin colours mainly （72）lie/consist in biology and history． |
| Biological reasons | The amount of melanin，by which a person's skin colour is （73）determined，varies from people to people．The more melanin a person has，the （74）darkerhis or her skin will be． Vitamin D is another source （75）affectingskin colour．Vitamin D is necessary for humans to build bones．Sunlight contributes to vitamin D production in the skin． |
| （76）Historical reasons | The earliest people in Africa had dark skin with hair covering it because the sunlight is very strong．． When they moved to places where they could not get enough sunlight to （77）producevitamin D，their skin colour became lighter． Generally speaking，people in areas with strong sunlight，have darker skin （78）whilepeople in other areas have lighter skin． |
| （79）Conclusion/Summary | Melanin （80）playsan important role in our skin colour．With our living environment changing，melanin production is changed，which leads to the changes in our skin colour． |
