For Intro to Anthropology, after exploring primate diversity, we read Chapter 5, “Human Origins & Earliest Hominins.” This page covers stone tools and material culture. For bipedalism, the earliest hominins, and the evolutionary-theory background—common ancestors, bushy evolution, lumpers and splitters, the species problem—see Bipedalism in Anthropology. Next is chapter 6 on human dispersal.
Key Concepts: Who Made the First Stone Tools
- Genus Homo emerges from Australopithecus. Between late Australopithecus and early Homo we see increased brain size, reduced face and teeth, and more gracile builds as diets shift away from heavy chewing.
- Homo habilis (~2.3 mya), “man the toolmaker.” Found at Olduvai Gorge with a larger braincase (143). The name reflects an outdated assumption—we now know chimpanzees, bonobos, and other primates make tools too.
- Oldowan tools (~2.6 mya) are the earliest secure stone tools (145-146), once tied to Homo habilis but no longer confidently attributed to any single species.
- You don’t need a big brain to make stone tools. The Gona tools (~2.5 mya) were likely made by Australopithecus garhi, not a Homo species—and several species may have invented toolmaking independently.
- The capuchin problem. Wild capuchin monkeys bash rocks and produce flakes that archaeologists cannot reliably distinguish from early human tools—so “intentional toolmaking” is harder to prove than it sounds.
- Flintknapping requires apprenticeship. Knapping a sharp edge is difficult enough that it must be learned by watching and imitating, then passed on as tradition.
- Early tools probably served scavenging, not hunting (146)—cracking bones for marrow after larger predators had finished, accessing protein without the hunt.
- Stone tools are the earliest preserved material culture (147): durable evidence that creatures were learning, teaching, and modifying their world.
- Three levels of culture: basic tool use (macaques flossing with human hair), cultural transmission between groups (chimpanzee grooming and tool traditions), and cumulative culture that builds across generations (humans) (148).
- Who do you picture making the tools? The “conquering hero” image imagines violent males, but anthropological evidence from contemporary groups often shows women making and using stone tools—a caution against projecting present assumptions onto the past.
- Archaeologists are custodians, not extractors. Finds belong to the places and peoples they come from; better interpretation comes from a more diverse field working beyond the usual sites.

Homo habilis and the First Stone Tools
After the australopiths—or overlapping with some of them—we see creatures that get placed in the genus Homo. This means scientists think they’re similar enough to existing Homo sapiens to put them in the same genus as us. The shift from late Australopithecus to early Homo shows an increase in brain size, a reduction in face and tooth size, and a more gracile, less robust build, as these creatures came to eat different foods and no longer needed heavy chewing teeth.
The first of these was Homo habilis, or “Handy Human,” appearing around 2.3 million years ago at Olduvai Gorge (143). The name literally means “man the toolmaker,” and when it was assigned, toolmaking was thought to be uniquely human. We now know from studying primates that various apes and monkeys make and use tools, so that assumption has been debunked. But the stone tools associated with early Homo are still significant—they represent a new level of sophistication and, crucially, they preserve in the archaeological record when wood, grass, and other materials simply decay.
Oldowan Tools: The Earliest Material Culture
The first stone tools we can securely identify are called Oldowan tools, appearing around 2.6 million years ago (145-146). You make them through a process called knapping—taking one stone and flaking off another to get a sharp edge. This is quite difficult to do; it’s not as easy as it looks. The difficulty suggests these creatures were transmitting their practices from one generation to the next through apprentice-style learning—learning by close association and watching someone else do it. You can’t figure this out on your own; you need to be shown. If you ever get the chance to try flintknapping yourself, you’ll find out how hard it is.
What were these tools for? It’s still debatable. Many have a sharp edge all around, which would cut your hand if you simply gripped them—so some researchers think these might be the cores left over after flaking off the actual tools, the byproduct rather than the product. Whatever their exact use, they probably enhanced early Homo’s ability to scavenge (146). When something died, the big predators and scavengers came in first; our ancestors could then move in with stone tools to crack bones for marrow and other nutrients others couldn’t access—animal protein without having to hunt. There are question marks all over this: butchering marks on animal bones near stone tools are the best evidence of use, but they are a rare find.
Importantly, you don’t need a large brain to make these tools. Some of the earliest, the Gona tools from around 2.5 million years ago, were probably made by Australopithecus garhi—not a Homo species at all. It looks increasingly like toolmaking may have arisen among several different species independently, which is one reason the Oldowan can no longer be pinned confidently to Homo habilis.
The Capuchin Problem: When Is a Tool a Tool?
Here’s a funny problem: it’s difficult to tell early stone tools from ordinary rocks. This became especially clear when researchers realized that capuchin monkeys bash stones together for no apparent reason—maybe they like the sound, maybe they like to lick the dust, who knows. The flakes they produce look very much like what we classify as early human tools. When researchers handed those capuchin-made flakes to archaeologists who specialize in human stone tools, the archaeologists couldn’t tell the difference.
So when you find something from this period, there are possibilities: it was made intentionally by early humans, or it was made unintentionally by monkeys bashing rocks. There’s even a third possibility nobody mentions—maybe early hominins were sometimes bashing stones together for fun too, and liked the sound as well. To get past the ambiguity, archaeologists look for deliberate shaping patterns, for hand bones anatomically adapted to toolmaking (144), and for butchering marks on animal bones near the tools (145). Those associations are what turn a suggestive rock into evidence of behavior.
Three Levels of Culture: From Macaques to Cumulative Culture
The most important thing about stone tools is what the textbook emphasizes: they provide the earliest archaeological evidence of material culture (147). Creatures are beginning to modify their environments in ways that can be transmitted to the next generation. This connects to niche construction—organisms constantly change their environments, and those changes alter the conditions of evolution for the generations that follow. Tool use creates new selective pressures, perhaps favoring better learning, and biology and culture co-evolve.
We can identify three levels of tool-related behavior. The first is basic primate tool use: macaque monkeys at temple sites in Indonesia and Bali have learned to floss their teeth with human hair taken from tourists—so if a monkey there pulls out your hair, it may be headed for dental use. The second is cultural transmission: among chimpanzees, different groups groom differently and use different tools, and these practices are handed down from generation to generation (148). The third, which we believe begins around the Homo genus, is cumulative culture: humans don’t just hand down traditions, they build on them, transforming the environment so that improvements accumulate and become part of the conditions of reproduction for the next generation (148). With writing and other record-keeping this becomes even more powerful, but all human societies show this accumulation across generations.
Who Do You Picture Making the Tools?
When we tell stories about the deep past, we have to be careful about what we might call the “conquering hero” narrative—the urge to project our own image of impressive people from today back onto the past, and then go looking for them there. This shapes paleoanthropology in real ways, from contests over who gets to name a new species to assumptions about who did what.
Consider stone tools. When we picture creatures bashing rocks, butchering, perhaps being violent—what do we imagine, gender-wise? Most people picture men. But the anthropological evidence from contemporary groups frequently shows women making and using stone tools, often for demanding, unglamorous work like scraping hides. That doesn’t prove women always made the tools in the deep past—assuming that would be its own projection. What it shows is that the default male image is an assumption, not a finding. The honest position is that we often don’t know, and our guesses reveal our biases.
The same caution applies to visual reconstructions. The artist renderings in the textbook are educated guesses: skin color, hairiness, and beards don’t fossilize, so those features are imagined, not read off the bones.
Custodians, Not Extractors
A diverse human past is best interpreted by a diverse community of researchers. Historically, paleoanthropology has been dominated by a narrow group—often elite white men—and conducted in a narrow set of places. Most major finds have come from Ethiopia, but there is much to learn elsewhere; the further the field reaches beyond Europe and the usual sites, the more it recovers of the human story.
This raises a question of stewardship. When researchers enter a region, the assumption that what they dig up belongs to the extractors—to be carried home and displayed in their own museums—is one to resist. Archaeologists and paleoanthropologists are custodians of the past, not owners of it. These are displaced ancestors. Giving due credit to the people of the places where finds are made, approaching the work with humility, and supporting good museums and exhibits everywhere are part of doing the science well.
Frequently Asked Questions
Who made the first stone tools?
We no longer attribute the earliest stone tools confidently to any single species. The Oldowan tools (~2.6 mya) were once linked to Homo habilis, but the older Gona tools (~2.5 mya) were probably made by Australopithecus garhi, which is not a Homo species. Several different hominin species may have invented toolmaking independently—and you don’t need a large brain to do it.
What are Oldowan tools?
Oldowan tools are the earliest securely identified stone tools, dating to around 2.6 million years ago. They are made by knapping—striking one stone with another to flake off a sharp edge—and they represent the earliest preserved evidence of material culture (145-147).
Why is Homo habilis called “Handy Human”?
Homo habilis means “man the toolmaker,” named around 2.3 million years ago when toolmaking was thought to be uniquely human. That assumption has since been debunked—chimpanzees, bonobos, capuchins, and other primates make and use tools—so the name reflects an outdated view (143).
Were early stone tools used for hunting?
Probably not, at least not primarily. The evidence points more toward scavenging: early Homo likely used sharp flakes to crack bones for marrow after larger predators had stripped a carcass, obtaining animal protein without hunting (146). The exact uses remain debated.
Did men or women make stone tools?
We often don’t know, and the common image of male toolmakers is an assumption rather than a finding. Anthropological evidence from contemporary groups frequently shows women making and using stone tools for work such as hide-scraping. Projecting either men or women onto the deep past risks reading our own biases into the evidence.
