Taming Fire - Setting Humans Apart from Animals

How does the use of fire demonstrate prehistoric people's ability to adapt to their environment?
The use of fire really shows us how humans were different from other animals. This is what started the whole evolution of humans, and tells us why humans became the leaders of the world and why gorillas, for example, didn't. People knew nothing about fire except for the fact that it was dangerous, and yet after a while they decided to question fire, question whether it could be of any use to them. They decided to harvest wildfires, which, although it was a very dangerous thing, helped people start to communicate among each other.
Fire helped early humans to adapt to their surroundings that they had been given in many ways. Fire gave them warmth, cooked food, and light.
It was essential for early humans to be warm for a couple of different reasons. For one, the ice age. The ice age was a very long period of time that required early humans to use what they had in order to create shelter and warmth. Their clothes, however, were not the warmest things around because they were just made of animal hides. This forced early humans to try and harvest wildfires to create fires in their camps. Somehow humans figured out that in order to ensure the survival of the human race, they would need to take some chances.
It was also very important for early humans to have cooked food. Cooked food was health and much more tasty. Without cooked food, humans got diseases and plagues and would very often die off in great numbers. This was because when a lot of food was raw, it would either have a lot of dangerous bacteria on it or it would be poisonous. The death rate increased steadily before the taming of fire and it was considered very old if one lived to the age of 35 or 40. Then, when fire was tamed, the death rate decreased and people learned to take better advantage of their surroundings.
Thirdly, it was important for early humans to get light from fire, because that way they could stay up after the sun went down. This allowed early humans to continue their work of the day after the sun went down. It also enabled them to have social time within their groups/families and start oral tradition, one of our most valuable sources. Fire helped early humans to communicate to each other about hopes, dreams, ideas, rules, and many more things that developed their culture.
In conclusion, our present culture only exists because of this important step in human evolution. The fact that humans actually managed to tame fire and use their brains for it is an incredible step in history. Without fire, we would be in a pretty bad situation here - we'd basically still be cavemen!
