How does the use of fire demonstrate prehistoric people's ability to adapt to their environment?

The fire shows a lot about how ancient people adapted to their environment, and how they try to fit in with their habitat, and the abiotic and biotic factors surrounding them. Ancient people realized that fire could provide them with heat, and that it can keep them warm during the cold weather. They have realized that fire can help them adapt to other, colder places, such as Europe and Asia. They realized that fire can ensure the survival of their species. They also found out that with fire they can cook food. Cooked food can help them stop ilnesses and food poisoning, because it kills the bacteria and germs. The cooked food tasted better and is more easily digested, as well. This shows that they adapted to their environment, because they have used the souces that they have the best possible way. They hunted the animals around them, and then cooked them by using fire that they have created by using natural resources surrounding their habitat. Ancient people also knew that the sun sets, and that night exists. They have tried to find a way to conquer this, and be able to stay up, and see around without the sunlight. Fire helped them acomplish this, and it also helped them start oral tradition, because, at night, the ancient people would gather around the fire, and socialize with their friends and family.
