What would human civilization be like if we are Herbivorous?
imagine if evolution led human to become complete Herbivorous. We can eat all grass, leaf, fruits, straw and all vegetables, like we do now. But not well design to eat meat. How would that influence human civilization and history?
Dramatically, I think. It's believed that humans incorporation of protein had a significant impact on the development of our brains.
It would drastically change our lives. But most people are not herbivores. Not even all animals are herbivores, the cow is the closes at 95% because a source of protein is needed. The development of the brain is interesting. If you look back in history the average brain size of Neanderthals was 1450cc while today it is 1250cc.
