But Eren and his colleagues suggest that for hundreds of thousands of years before hominins learned to manufacture stone flakes, they simply collected and used ones already lying around. These naturaliths may have been produced in a variety of ways\u2014rockfalls, erosion, wave action, glacial activity, and even trampling by large animals like elephants.<\/p>\n<blockquote>\n<p>\u201cIn some places, nature makes hundreds or even thousands of these naturally sharp stones,\u201d said co-author Michelle R.

They found that in many environments, these fragments were not rare at all. Some sites had thousands of sharp stone pieces scattered across the landscape, indistinguishable from early hominin-made tools.<\/p>\n<p>The study argues that before the first knappers, hominins were already using sharp objects to process food. This likely started with bone flakes created during marrow extraction. Experiments with modern tools suggest that bone fragments can be used effectively to cut meat, but stone flakes are significantly sharper. If hominins were already using bone flakes, it\u2019s not hard to imagine them picking up a naturalith and recognizing its advantage.<\/p>\n<blockquote>\n<p>\u201cOnce you start using sharp-edged materials, you eventually start looking for ways to get more of them,\u201d Eren said. \u201cIf you\u2019re in an area with no naturaliths, you have a problem. That\u2019s where knapping becomes useful.\u201d<\/p>\n<\/blockquote>\n<p>The researchers suggest that naturaliths served as a bridge between using bone flakes and intentionally striking rocks together to make sharp stone tools. This gradual shift\u2014from opportunistic use to controlled production\u2014may have set the stage for the technological explosion of the Oldowan industry around 2.6 million years ago.<\/p>\n<p>The traditional view of early toolmaking suggests that one particularly clever hominin, perhaps while cracking a nut or smashing a bone, accidentally broke a rock and discovered the sharp edges it produced. But the new hypothesis suggests that knapping wasn\u2019t an accident\u2014it was an imitation of nature.<\/p>\n<blockquote>\n<p>\u201cRather than being a sudden breakthrough, early knapping was likely an attempt to copy something that already existed,\u201d said Eren. \u201cHominins weren\u2019t inventing something new, they were figuring out how to make more of what they already used.\u201d<\/p>\n<\/blockquote>\n<p>This changes how archaeologists might interpret the earliest evidence of stone tool use. If early hominins were using naturaliths, then traces of tool use\u2014cut marks on bones, for example\u2014might predate the oldest known knapped tools. Future research will need to look for signs that early hominins collected and carried naturaliths before they mastered making their own.<\/p>\n<p>If early humans relied on naturaliths before learning to knap, it raises new questions about how our ancestors thought about technology. The ability to recognize and select useful objects in the environment is a key cognitive step in human evolution.<\/p>\n<p>The findings also suggest that archaeologists should reconsider the definition of tool use in the fossil record. If a sharp stone was used by a hominin but not modified, does it still count as a tool?<\/p>\n<blockquote>\n<p>\u201cIf naturaliths were being used extensively, then the history of tool use is likely much older than we think,\u201d Bebber said. \u201cAnd that means the origins of human technology are more complex than a single moment of invention.\u201d<\/p>\n<\/blockquote>\n<p>To test the hypothesis, archaeologists will need to analyze ancient sites for patterns suggesting naturalith use. This could involve examining sites older than 3.3 million years\u2014the age of the earliest known stone tools\u2014to look for cut marks on bones that may have been made with unmodified rocks. Experimental archaeology could also help determine whether naturally occurring flakes are sharp enough to leave distinct traces that can be identified in the fossil record.<\/p>\n<p>For now, the study challenges long-standing assumptions about the origins of tool use. Rather than a single discovery that launched the Stone Age, early hominins may have been cutting with sharp rocks for millennia before they ever struck two stones together with purpose.<\/p>\n<ol>\n<li>\n<p><span>Harmand, S., Lewis, J.
