History of cooking

There is, as yet, no clear evidence as to when cooking was invented. Richard Wrangham argues that cooking was invented as far back as 1.8 million to 2.3 million years ago. Other researchers believe that cooking was invented as late as 40,000 or 10,000 years ago. Evidence of fire is inconclusive as wildfires started by lightning-strikes are still common in East Africa and other wild areas, and it is difficult to determine as to when fire was used for cooking, as opposed to just for warmth or keeping predators away. While many anthropologists place the advent of cooking at around 250,000 years ago, anthropologists besides Wrangham suggest that cooking did indeed occur much earlier, evidenced by archeological findings at Zhoukoudian in China, at Chesnowanja, Swartkrans and Koobi Fora in Africa, the latter of which has been dated by the "potassium-argon method to approximately 1.6 million years ago".
