Scientists at Harvard have come to the conclusion that humans began to evolve when they began to cook meat. This would have been due to the increased energy that comes from eating cooked meat and vegetables.
HEATING food advanced human evolution because cooked meat and vegetables provide the body with more energy than raw food, US scientists said today.
Researchers from Harvard University came to the conclusion after studying the diets of two groups of mice, one fed on raw meat and vegetables and the other on cooked.
They found that regardless of whether the rodents were fed meat or vegetables, the cooked variety delivered greater amounts of energy, leading to bigger, stronger mice.
