The Congo River. Crossing continent is the living pulse of Africa. The deepest river in the world, a haven for countless wild creatures. The Republic of the Congo is named after the Congo River, which crosses this country on its way to the Atlantic. The second largest tributary of the Congo - Ubangi flows to the north, and here the width of the Congo reaches almost 15 kilometers. It serves as a giant moat, which even the strongest swimmers and birds from Central Africa can not overcome. Due to this, the Congo River changed the evolution of the higher primates. When millions of years ago this river was formed, it displaced our closest relatives on this planet to the northern shore.
