Fat, Not Meat, May Have Led to Bigger Hominin Brains
One of the first <i>human</i> foods was actually bone marrow which is basically pure fat.<p>This happened about 2MYA by Homo habilis who figured out that you could use rocks to bust open bones.<p>Lions and Hyenas would leave huge piles of bones in the middle of the dessert which had been picked clean by vultures.<p>One of our ancestors had the brilliant idea to use a rock to bust open the bones.<p>Well it's a massive source of free calories.  It's absolutely brilliant.  It's just sitting there and there are no other predators or species around to fight with at that point.<p>It's also very safe to eat even days after since the marrow is wrapped in bone.<p>Next time you're out at a fancy restaurant and they have bone marrow GET IT...<p>Then realize you're eating one of the first foods that modern man ate and think of the gift he gave us.
