The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of mankind. The exact date of its discovery is not known; evidence of burnt animal bones at the Cradle of Humankind suggests that the domestication of fire occurred before 1,000,000BCE; scholarly consensus indicates that Homo erectus had controlled fire by between 500,000BCE and 400,000BCE. Fire, fueled with wood and charcoal, allowed early humans to cook their food to increase its digestibility, thereby improving its nutrient value and broadening the number of foods that could be eaten.
