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

The fact that ancient people used fire tells us quite a lot about how they adapted, changed and advanced in thier communities. Once the early humans uncovered the full potential and power of fire, they developed many different uses for it, they used it for heat, protection, cooking and it also allowed them to stay up later in the dark to socialize which was also a factor in the developement of language. Later on in the adventure with fire, the ancient people realized they could migrate to different areas and even colder areas which they could not survive in before the uncovering of fire. In many ways it continued the growth of the human specie, cooking prevented food poisoning, it kept them away from harmful animals that could eat them, and gave them better shelter and a source of heat. The fact that fire gave longer socializing hours promoted development of language, developement of families, and most importantly the development of oral tradition.
