I love it when the modern science backs up the ancient science of Ayurveda.
Here Neuroscientist Suzana Herculano-Houzel explains how we would not have evolved into the ever-so-advanced species that we are without having discovered cooking. Without the technology of cooking we would have to spend a full half of our time chewing food. Not an efficient use to time for a smart ape. We are primates but we are not monkeys and this is one of the clearest explanations I have heard of how we became human.
