Taming Fire; The first scientist

Have you ever thought about fire and how it saved and helped humanity. You probably didn't. Well a resource which modern humans use rarely was once a key thing to survival. Scientist estimated that humans have been using fire for at least 250,000 but they were most likely wrong, because they found animals bones in a cave somewhere in Swartkrans that were completely burned up. And the temperature used to cook them was too high for it to be a wildfire thus making fire use be older then a 1,000,000 years. In the past humans would have used hearths {a fire place made out of stone}, often identified by a circle of rocks around it. And inside of them were bones, animal remains if you will. Like i mentioned before hearths have a higher temperature of heat then any other natural fire like wildfire, but of course not as hot as lava. Who ever seemed to ignore all of the consequences of fire changed human evolution for the better. A result of this would be food because with fire it is easier to digest it and fire also cleans up all the bacteria and worms. Another big influence fire made was the immigration of early humans form Africa to Europe and Asia, which expanded the life of early humans. Fire also protected early humans from dangers predators while they were sound asleep. As you can see their are lots of ways that fire helped us humans, in fact to much for me to write but these are the most basic ones. With out someone taking a risk we would have never discovered fire this early.
