Explanation:
They were made from large flakes that were struck from boulder cores or from larger cobbles and nodules. Tools were more extensively shaped than before, as seen in the large range of proficiently created retouched tools such as backed knives, awls and side scrapers.
Answer:
The earliest stone toolmaking developed by at least 2.6 million years ago. The Early Stone Age includes the most basic stone toolkits made by early humans. The Early Stone Age in Africa is equivalent to what is called the Lower Paleolithic in Europe and Asia.
The oldest stone tools, known as the Oldowan toolkit, consist of at least:
• Hammerstones that show battering on their surfaces
• Stone cores that show a series of flake scars along one or more edges
• Sharp stone flakes that were struck from the cores and offer useful cutting edges, along with lots of debris from the process of percussion flaking
By about 1.76 million years ago, early humans began to strike really large flakes and then continue to shape them by striking smaller flakes from around the edges. The resulting implements included a new kind of tool called a handaxe. These tools and other kinds of ‘large cutting tools’ characterize the Acheulean toolkit.
The basic toolkit, including a variety of novel forms of stone core, continued to be made. It and the Acheulean toolkit were made for an immense period of time – ending in different places by around 400,000 to 250,000 years ago.
