Eating meat is thought by some scientists to have been crucial to the evolution of our ancestors’ larger brains about two million years ago. By starting to eat calorie-dense meat and marrow instead of the low-quality plant diet of apes, our direct ancestor, Homo erectus, took in enough extra energy at each meal to help fuel a bigger brain. Digesting a higher quality diet and less bulky plant fiber would have allowed these humans to have much smaller guts. The energy freed up as a result of smaller guts could be used by the greedy brain, according to Leslie Aiello, who first proposed the idea with paleoanthropologist Peter Wheeler. The brain requires 20 percent of a human’s energy when resting; by comparison, an ape’s brain requires only 8 percent. This means that from the time of H. erectus, the human body has depended on a diet of energy-dense food—especially meat

From around 6 million years ago to 2 million years ago, the ancestors of modern humans had pretty small brains. For about 4 million years, our brains were basically the same, and pretty unimpressive by modern standards.
But then we started eating meat. The ancestors of modern humans started eating meat around 2.5 million (2,500,000,000) years ago (for reference, the Agricultural Revolution, when we started eating grains as our staple food, was only around 10,000 years ago). With the introduction of meat into our diets, our ancestors’ brains started rapidly increasing in size and complexity.

יש גם הערכות שלבישול בשר היה חלק בזה, ככה בני האדם הקדמונים היו מבשלים בשר שגרם ללסת שלנו להיות קטנה יותר וחלשה יותר ולפנות יותר מקום למוח, וגם עצם הצייד של הבשר פיתח את המוח שלנו כי היינו צריכים לשיתוף פעולה, לא צריך להיות גאון כדי לשים לב שטורפים בטבע הרבה יותר חכמים מהנטרפים, תסתכל על צבועים ועל השיתוף פעולה שלהם, הם אפילו יודעים לנשוך את הטרף שלהם בביצים כדי שיהיה לטרף יותר קשה להגיב
