Ohio has been home for people for at least 15, years. Beginning at the end of the Ice Age, various American Indian societies successfully occupied this area. The groups that lived here prior to around AD are usually called "prehistoric" because their accomplishments were not recorded in written documents to which we can have access today. We can learn about them through archaeology, the systematic study of the places where they lived-their "sites"-and the objects that they left behind-their artifacts. Over the past century, archaeologists have determined that some prehistoric cultures were hunters and gatherers, moving from camp to camp as the seasons changed, while others were gardeners and farmers, settling in more permanent communities supported by their crops. Some of these prehistoric cultures were quite sophisticated, developing wide-ranging trade networks, encouraging skilled artisans, and building large-scale earthen monuments that still dominate parts of our landscape.
By Ian Randall For Mailonline. Ancient humans living in the early Stone Age made tiny flint tools by recycling old hand axes, allowing them to butcher animals with surgical precision. The researchers had analysed hundreds of the tiny stone tools to determine how they were used and even found residues of flesh and bone on some. The findings suggest that early Stone Age technology was far more advanced than previously thought and used carefully by a people who wasted little of their kill. And, although the tools can't be considered early examples of cutlery because people didn't eat with them, they would have allowed food to be prepared with exactitude. The site is known for its stone tools — including dozens of hand axes — and animal remains, which were predominantly straight-tusked elephants. Each of the flints date back to the so-called Lower Palaeolithic, or Early Stone Age, around ,—, years ago.
During the early and middle Palaeolithic, human ancestors such as Homo erectus developed Mode 2 Acheulian biface axes. They also made side scrapers and end scrapers that tended to be on thick flakes. Click thumbnails to enlarge. In the Upper Palaeolithic , Neanderthal humans made Mousterian biface axes with a characteristic flat base, and scrapers which continued to be made on thick flakes. Later in the Palaeolithic, modern humans made Aurignacian industry flint tools that included pointed blades and more finely worked scrapers. In Mesolithic times, our ancestors made fine hunting tools, arrows and spears, using microliths.
