Flakes and Cores. Stone tools were made by taking a piece of stone and knocking off flakes, a process known as "knapping. Flint was commonly used for making stone tools but other stones such as chert and obsidian were also used. Palaeolithic and Mesolithic people were nomadic hunter gatherers.
Early humans in East Africa used hammerstones to strike stone cores and produce sharp flakes. For more than 2 million years, early humans used these tools to cut, pound, crush, and access new foods—including meat from large animals. Scientists have made experimental stone tools and used them to butcher modern animals. In archaeology, a hammerstone is a hard cobble used to strike off lithic flakes from a lump of tool stone during the process of lithic reduction.
The hammerstone is a rather universal stone tool which appeared early in most regions of the world including Europe, India and North America.
Blombos Cave. Blombos Cave, on the South African coast east of the Cape of Good Hope the Southern tip of Africa , is an important archaeological site with evidence of human habitation from about 95, to about 55, years ago. Materials found at the site can tell us a lot about early human life. List of Neolithic Stone Tools. Scrapers are one of the original stone tools, found everywhere where people settled, long before the Neolithic Age began. Arrows and Spearheads.
Hammers and Chisels. They would eat wild berries, fruit, some grains, plants, and roots. It was not just a steady progression from the primitive Australopithecus species best represented by Lucy to Homo erectus and then to more modern Neanderthals and fully modern humans. Instead, various species lived alongside each other and in some cases interbred. IE 11 is not supported.

I would place all this as an even more significant transition than the initial use of stone tools. Homo erectus evolved in ways "to make getting access to meat and efficiently digesting meat more successful — you've got increased brain size, about two-thirds that of the modern human average, and increased body size," Bunn said.
This doesn't mean that early stone tools were restricted to just processing animal carcasses, Bunn noted, "or that meat became a dominant factor in their lives, since by all indications, from chimpanzees to tropical hunter-gatherer people today, plants are the dominant day-to-day part of the diet.
It just shows an increased interest in meat. As tool use evolved, "somewhere along the line, there had to have been really important changes in social evolution," Wynn said. Scientists argue, for instance, when provisioning or the sharing of food began. So the suggestion is that provisioning helps females find something to eat. There are two ideas regarding provisioning. One is that males are the ones bringing food over due to pair-bonding between the sexes.
Another is the "grandmother hypothesis," where grandmothers bring their daughters food to help them raise their offspring. Still, Wynn noted other research has suggested primates spread throughout the Old World do possess these female links, "and Homo erectus has a very different distribution from the African apes, were distributed more widely in Africa and Asia, and so maybe Homo erectus mimics the behavior of these other primates.
