Some people believe that the human brain evolved from the ape-size 350cc to the present-day human-size 1300cc after our distant ancestors started to eat meat. This Meat:Brain Hypothesis is driven by the carnist view that human supremacy resulted from vegetarian apes who evolved by dominating other animals. This hypothesis has been around since at least the early 1900s and started to fall apart around 1980. By now, the Meat:Brain Hypothesis is thoroughly debunked, yet it persists in some scientific and public circles.
This video lecture, filmed at Santa Monica College in July 2019, reviews the evidence and argument that explains why progressively social prehumans and early humans caused our brain to grow. Cooked food (plants or animals) was only the fuel for that growth, not the cause. And meat was barely a food source since the prehuman and early human diet was almost entirely plant-based, including cooked tubers like yams. The role of meat in the prehuman and early human diet may have gotten us through some periods of starvation but that doesn't mean that meat should be credited for making our big brain, just like occasional gusts of wind are not the fuel nor cause of your airplane travels.
