127 Wrangham accompanies it with the fact that cooking food was the sine qua non in order to give energy to an increasingly large and awake brain. Ours is three times larger than that of any primate, and it requires 20% of energy consumption at rest. Due to cooking, the relationship between Homo and food changes, so much so that it involves less intestine and allocates to the brain the necessary contribution to its evolution. Thus, we collect the rests of Homo Heidelbergensis, which lived 700 thousand years ago, with a brain 30% higher in mass, certainly capable of lighting fire when desired and whose remains were brought to light in Germany, Greece and China. Then came the Homo Neanderthalensis, that certainly ate and cooked vegetables and large animals. There is no lack of evidence for these Erectus’ evolutions. If fires and bones of animals dating back to 2 million years ago cannot necessarily be traced back to cooking and slaughtering the meat, halving the time that separates us from this scenario, an abundance of evidence demonstrates the culinary evolution of this species. Bones, feces, tartar. In the microscopic legacies of fibers and deposits found on the discovered specimens, evolution here knows fire applied to food and its consequences on humans. These traces are also found far from Africa, sharing all the expressions for the same species, the first that the present day will find at various latitudes and longitudes of the globe. A journey started in coincidence with the evolution of the brain which, once alimented, opened up to the world and its interactions.
