Fat frenzy: did an early taste for bone marrow fuel hominin brain development?
Four million years ago, our hominin ancestors’ appetite for fat could be what delivered the energy needed to develop big brains and evolve into modern humans, anthropologists suggest.
In a paper published in the journal Current Anthropology, they theorise that our early ancestors, long before they developed tools with which hunt and eat meat, smashed open bones left by predators to eat the fat- and nutrient-rich marrow sealed inside.
