Cooking transformed human evolution as it was a determining point in human history. The important topic of debate is when did this change take place? All evolved societies consume cooked food and it played a vital part in the human body evolution. For example; cooked food is softer and easier to chew and digest than the raw food. Cooking also enhance the energy levels acquired by the food they consume.
Starchy potatoes and other tubers, consumed by people globally, are scarcely digestible when raw. On top of it if we imitate Chimpanzees and other primates and eat what they consume it would be deficient in nutrients therefore cannot support a healthy lifestyle. Up to 50 % women who consume a major share of raw foods embellish amenorrhea, or lack of menstruation a symbol that the body does not possess enough energy bear a pregnancy, a major impediment to evolution.
Such proof proposes modern humans are biologically dependent on cooking. But where did this new practice emerge in the timeline of evolutionary history. Some researchers are of the view that cooking is a relatively recent phenomenon, at most 500,000 years old. Cooking necessitates dominance of fire, and there is a lack of archaeological proof for hearths and resolutely built fires before this time.
The archaeological record becomes progressively brittle farther back in time. Other’s contemplate that fire may have been regulated much earlier. Anthropologist Richard Wrangham has suggested that cooking arose before 1.8 million years ago, an invention of our evolutionary ancestors.
