You compare the size of our digestive system to, for example, cows. We devote less of our head to our mouth, and less of our body to our digestive tract. This is because we begin the digestive process externally, in cooking and cutting food. This efficiency allows us to direct the nutrition we do digest to other functions, most crucially the development of our brains. Humans who lack a wholesome diet don’t develop their physical or mental capability.
