Taming Fire= adaptation

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

Even in ancient times we knew that fire was dangerous. Scientists believe that early people were exposed to fire caused by natural phenomenons such as lightning, but they feared it. This was the case until an unknown person decided enough and tamed fire. The dangers of fire were obvious, but so were the advantages. After a natural fire, animals that didn't make it out were toasted and edible. The fire cooked meat saved people from parasites that were growing on the animal, bacteria, it was easy to digest, and allowed people a greater variety because it cooked out the toxins that made food in-edible. Early humans created hearths to help them tame the fire. They discovered that by arranging rocks in a circle around the flame, there was less of a chance of it escaping. Early people knew how to tame fire, but we don't think that they knew how to make it from scratch. Scientists think that people brought flaming or singed logs up to there dwellings, and then had to keep it alive. At night, fire proved to be a plus. It gave off an excellent light source, allowing people to stay up later and exchange stories. This could have been the start of oral tradition. It also proved itself as an excellent defensive system. It could ward off wild animals, keeping people much safer. Fire proves that people can adapt to whats around them and put it to use
