The Reason for Our Evolution

Theories talk about the motives and causes of evolution. Darwin explained our origin from primates and the mechanism of evolution of natural selection, but in our case, it is not yet clear. Are free hands important? What about upright gait and brain volume? It is widely believed that free hands and upright gait made it possible to meet the need for food, thus enabling brain development. The author points out that the brain is important, but its development is the understanding of abstraction! Two million years ago, the volume of our brain (not our hands) developed abruptly. Can you imagine how much of a need there was for such great brain growth? Today we live in a technological age and the volume of the brain has not increased even by a millimeter! In theory, it can be imagined what was the initiator of the brain enlargement. It's a belief! The author explains how and why the primate began to believe. Over time, belief has enabled the evolution of the brain to understand abstraction.
