The Oldowan Culture is frequently defined by rolled stone cobbles or nodules of stone with removed few large flakes from one side to create a cutting edge which was not modified.In addition, the Oldowan is defined by the presence of a few other key objects: discoids, polyhedrons, spheroids, and simple bifaces. This culture is mostly associated with the Homo habilis. A landmark study by Nicolas Toth showed that unmodified flakes are actually much sharper than the core tools, such as the characteristic choppers.
Compared to previous periods, the climate of eastern Africa was generally colder, but more importantly, it was variable. There were significant swings between warm and wet and cold and dry. Similarly, the landscape frequently changed from forested to grassy. Animal life was in great flux with successions of organisms suited to survive in those environments. Hominids and their hominin descendants grew increasingly dependent on tools to survive the changing environments.
