Received : 29 January Accepted : 09 October As with all such finds, it is necessary to demonstrate that these fires were the result of deliberate actions by pre-humans and not the result of a natural event such as a lightning strike.
Two features of the patches at Koobi Fora provide highly persuasive evidence that H. The second is the composition of the plant matter used for fuel, as indicated by phytolith analysis [1]. Campfires, by design, burn much hotter than natural brushfires. This is accomplished by better air flow and more suitable fuel. Everyone knows from experience how the bark surrounding tree and bush branches burns slowly, protecting the rest of the wood. One reason we use chopped wood in most hearths is that the interior, drier wood burns faster and hotter than the outer bark.
Another is that cut wood has more surface area, allowing more air to fuel a fire. Therefore, evidence that the fires at Koobi Fora burned at higher temperatures suggests they were deliberately assembled and tended by the hominids who camped there.
The question is then: did they have the reasoning and forethought to do so? The phytolith analysis may help to answer that question. Phytoliths are nearly-indestructible silica deposits found in plants.

They are survived by today humanity, of wich the vast majority can not care less of when Ahhhk and Nhhhk discover how to use the fire. Thanks fernandogomezbolivar I always heard it was the Uhhhrk brothers. But never knew the story behind about them. One point not noted: fire enabled cooking.
