The Way We Lived for Two Million Years

Here's a fact that might reshape how you think about human nature: for roughly ninety percent of our existence as a species, we lived as hunter-gatherers. Agriculture, cities, smartphones, and everything we call "civilization" occupy only the final sliver of our timeline. The way your ancestors lived for nearly two million years—roaming in small bands, foraging for plants, hunting game—isn't ancient history. It's the default human condition.

And some people still live this way today.

What Hunter-Gatherers Actually Do

The term "hunter-gatherer" describes people who obtain most or all of their food from wild sources rather than farming. They gather edible plants, nuts, fruits, and eggs from their environment, and they hunt or fish for meat. This isn't some exotic human invention—it's actually the standard approach among omnivorous vertebrates. We're the odd ones out for farming.

Hunter-gatherer groups typically consisted of a few dozen people, often several families traveling together. They were usually nomadic or semi-nomadic, following food sources as seasons changed. This stands in stark contrast to agricultural societies, which stay put, cultivate crops, and raise domesticated animals.

The distinction matters more than you might think. When humans shifted from foraging to farming around ten thousand years ago, it triggered cascading changes in social organization, health, inequality, and environmental impact that we're still navigating today.

The Deep History

Hunting and gathering emerged with Homo erectus approximately 1.8 million years ago. When our own species, Homo sapiens, appeared around 200,000 years ago, we inherited this lifestyle and refined it. For context, the agricultural revolution began only about 12,000 years ago. That means modern humans spent roughly 94 percent of our species' existence as foragers.

During the Late Pleistocene—the geological epoch that ended about 11,700 years ago—modern humans spread from Africa across the entire globe. We reached Australia around 50,000 years ago and the Americas roughly 15,000 years ago, crossing from Asia via the Beringia land bridge, a stretch of land now submerged beneath the Bering Strait.

These migrations coincided with massive extinctions of megafauna—woolly mammoths, giant sloths, saber-toothed cats, and dozens of other large species. Whether humans hunted them to extinction, outcompeted them, or simply arrived alongside climate changes that doomed them remains debated. Probably all three factors played roles in different places.

Were Early Humans Hunters or Scavengers?

In the 1970s, anthropologist Lewis Binford proposed a provocative idea: maybe early humans weren't really hunters at all. Perhaps they were primarily scavengers, picking meat from carcasses killed by predators or animals that died naturally.

The evidence is genuinely complicated. Early humans in the Lower Paleolithic period lived in forests and woodlands where they could collect seafood, eggs, nuts, and fruits without needing to tackle dangerous prey. Scavenging would have been safer and required less coordination than hunting large animals.

Scientists now recognize that the answer depends heavily on local ecology. In some environments and time periods, scavenging probably dominated. In others, active hunting made more sense. The key insight is that our ancestors were opportunistic and flexible—they did whatever worked given their circumstances.

The Specialization Revolution

Something interesting happened between 80,000 and 70,000 years ago during the transition from the Middle to Upper Paleolithic period. Hunter-gatherer bands began specializing. Rather than exploiting every available food source equally, some groups concentrated on hunting specific large game while gathering a narrower selection of plants.

This specialization drove innovation. People developed fishing nets, hooks, and bone harpoons—tools designed for specific purposes rather than general use. Archaeologists can track these changes through stone tool assemblages, which become more varied and sophisticated during this period.

Specialization also enabled some groups to become sedentary. The indigenous peoples of the Pacific Northwest Coast, for instance, lived in such fish-rich environments that they could stay in one place year-round. The Osipovka culture in the Russian Far East, dating from 14,000 to 10,300 years ago, represents one of the earliest known permanent settlements, sustained entirely by abundant fish.

The Chumash people of coastal California achieved something remarkable: the highest recorded population density of any known hunter-gatherer society, with an estimated 21.6 persons per square mile. For comparison, that's denser than many rural agricultural communities.

The Egalitarian Puzzle

Here's where things get philosophically interesting. Hunter-gatherer societies are remarkably egalitarian. Not perfectly equal—no human society ever achieves that—but strikingly so compared to virtually every other form of human organization.

Consider the San people of southern Africa, sometimes called "Bushmen." Their social customs actively discourage hoarding and displays of authority. They share food and material goods extensively. Karl Marx, observing similar patterns across foraging societies, called this arrangement "primitive communism."

The contrast with our closest primate relatives is dramatic. Chimpanzees organize themselves into rigid hierarchies typically dominated by an alpha male. The difference is so pronounced that many paleoanthropologists argue resistance to domination was a key evolutionary pressure shaping human consciousness, language, and social organization. We evolved, in part, to prevent bullies from taking over.

How did hunter-gatherers maintain equality? Several mechanisms worked together. Nomadism meant you couldn't accumulate more possessions than you could carry. Sharing norms redistributed windfalls like successful hunts. Mockery and social ostracism discouraged anyone who tried to act superior. Most importantly, there were no permanent leaders—authority shifted depending on the task at hand.

The Division of Labor Question

For decades, anthropologists assumed a straightforward division: men hunted, women gathered. This made intuitive sense. Hunting large game is dangerous and requires extended time away from camp, while gathering can be done while caring for children.

Recent research has complicated this picture considerably.

A 2023 study examining contemporary and historical hunter-gatherer societies found that women participated in hunting in 79 percent of the groups studied. Among the Ju/'hoansi people of Namibia, women help track quarry. In Australian Martu communities, both sexes hunt, though they employ different strategies—men take more risks pursuing larger game like kangaroos, while women focus on smaller, more reliable catches like lizards.

Archaeological evidence reinforces this revision. In 2018, researchers discovered 9,000-year-old remains of a female hunter at Wilamaya Patjxa in Peru, buried with projectile points and animal processing tools. A follow-up study examining 27 hunter-gatherer burials with associated hunting tools found that 11 were female and 16 were male—suggesting women may have constituted 30 to 50 percent of big game hunters.

However, critics note methodological problems with some of these studies, arguing they don't necessarily overturn the evidence for gendered divisions of labor in foraging societies. The truth probably varies significantly across cultures and time periods.

One compelling theory suggests that a more flexible sexual division of labor gave Homo sapiens an advantage over Neanderthals. Our ability to organize work differently may have helped us spread across the globe while our evolutionary cousins went extinct.

The Original Affluent Society

In 1966, anthropologist Marshall Sahlins presented a paper that challenged centuries of assumptions about hunter-gatherer life. The philosopher Thomas Hobbes had famously described the state of nature as "solitary, poor, nasty, brutish and short." Sahlins argued the opposite: hunter-gatherers were the original affluent society.

His evidence was striking. Ethnographic data showed that foragers worked far fewer hours than people in industrial societies while still eating well. Their "affluence" stemmed not from abundance but from wanting little. With modest material desires and reliable food sources, they enjoyed extensive leisure time.

Later research partially supported Sahlins. A 1996 meta-analysis found that adults in foraging and horticultural societies work an average of about 6.5 hours per day, compared to 8.8 hours in agricultural and industrial societies. That's more than two hours of extra free time daily.

But Sahlins' romantic view has serious limitations. His calculations excluded time spent collecting firewood, preparing food, making tools, and other necessary labor. More importantly, hunter-gatherer life included extremely high infant mortality, frequent disease, and recurrent violence. Researchers estimate only 57 percent of hunter-gatherers reached age 15, and life expectancy ranged from 21 to 37 years. About 70 percent of deaths came from disease, 20 percent from violence or accidents, and 10 percent from degenerative conditions.

The "original affluent society" was real in some ways—foragers probably did enjoy more leisure and less tedious labor than peasant farmers. But it wasn't a paradise.

Inequality Existed, Just Differently

A 2010 study found that while hunter-gatherers had lower inequality than modern industrialized societies, they weren't perfectly equal. The average Gini coefficient—a standard measure of inequality where 0 represents perfect equality and 1 represents perfect inequality—was about 0.25 among hunter-gatherers, roughly equivalent to Denmark in 2007.

More surprisingly, wealth transmission across generations existed in these societies. "Wealthy" hunter-gatherers, within their community's context, were more likely to have children who were also relatively well-off. Some social stratification was present, even if less pronounced than in agricultural societies.

This finding undermines simple narratives about egalitarian primitive communism while still acknowledging that foraging societies distributed resources more evenly than most alternatives.

We should be cautious, though, about extrapolating from contemporary hunter-gatherers to prehistoric ones. Today's foraging societies have experienced 10,000 years of contact, trade, and change since the agricultural revolution began. They may not accurately represent Paleolithic social structures.

Diet and Ecology

Hunter-gatherer diets varied enormously depending on environment. Near the equator, plant foods dominated. As you move toward the poles, aquatic resources become increasingly important. In cold, heavily forested regions, edible plants and large game are scarce, pushing people toward fishing and marine hunting.

Fat was crucial. Lean meat, counterintuitively, can be dangerous. Consuming too much protein without adequate fat leads to a condition sometimes called "rabbit starvation" or protein poisoning—the body struggles to metabolize excessive protein, potentially causing diarrhea, headache, fatigue, and in extreme cases, death. Hunter-gatherers often considered lean animals secondary food sources or even starvation rations.

This creates interesting dynamics. In seasons when animals become lean, hunter-gatherers faced genuine nutritional challenges even when meat was abundant. Some groups solved this through trade with horticulturalists—exchanging protein-rich meat for carbohydrate-rich plant foods.

Marine foods probably didn't become dietary staples until relatively recently in human evolution—during the Late Stone Age in southern Africa and the Upper Paleolithic in Europe. Fishing requires specialized technology like boats, nets, and hooks, which may have delayed its intensive exploitation.

The Transition to Agriculture

Around 12,000 years ago, some hunter-gatherer groups began cultivating plants and domesticating animals. Why they made this transition remains debated. Climate change, population pressure, depletion of wild resources, and cultural innovation all probably played roles.

The shift wasn't obviously beneficial. Early farmers were shorter, sicker, and harder-working than the foragers they descended from. Skeletal evidence shows increased malnutrition, dental problems, and repetitive stress injuries. Agricultural diets were less varied and more dependent on a few crops, making famines more devastating when those crops failed.

So why did farming spread? Primarily because agricultural societies could support larger, denser populations. Farmers outbred and eventually displaced or absorbed hunter-gatherers across most of the world. In Western Eurasia, farming and metallurgical societies gradually pushed foragers into increasingly marginal territories—dense forests served as their last refuge until Bronze and Iron Age technologies allowed farmers to clear even those.

Agriculture also enabled permanent settlements, which led to accumulation of possessions, development of governments, emergence of social classes, and eventually the complex civilizations we inhabit today.

Hunter-Gatherers Today

Only a handful of societies still practice pure hunting and gathering. Most contemporary groups classified as hunter-gatherers actually supplement foraging with some horticulture or pastoralism.

The San people of southern Africa maintain aspects of their traditional lifestyle, though they increasingly engage with the modern economy. The Pumé of Venezuela continue foraging practices. The Sentinelese of North Sentinel Island in the Indian Ocean remain uncontacted and presumably live entirely as their ancestors did—we know almost nothing about them because they violently resist any approach.

These contemporary groups offer windows into our past, but we must view them carefully. They're not living fossils frozen in time. They've adapted and changed over millennia, faced pressures from expanding agricultural and industrial societies, and made choices about what traditions to maintain. They represent possible ways of living as foragers, not necessarily the exact patterns of our Paleolithic ancestors.

What Hunter-Gatherers Teach Us

Understanding hunter-gatherer societies matters beyond academic curiosity. These patterns shaped human nature during our species' formative millennia. Our psychology, social instincts, and even our bodies evolved in foraging contexts.

The tension between our evolved preferences and modern circumstances may explain some contemporary problems. We evolved in small groups where everyone knew everyone—now we navigate anonymous crowds. We evolved for feast-and-famine cycles—now we face constant food abundance. We evolved for physical activity integrated into daily life—now we sit at desks and must artificially "exercise."

Hunter-gatherer societies also challenge assumptions about human nature. Are hierarchy and inequality inevitable? Foragers suggest otherwise—humans can organize egalitarian societies under the right conditions. Is war built into our genes? Some foraging groups were remarkably peaceful, suggesting violence is more culturally variable than often assumed. Do humans need less to be happy than consumer culture suggests? The "original affluent society" thesis, despite its flaws, raises profound questions about what we actually need versus what we've been taught to want.

The hunter-gatherer way of life isn't returning, and romanticizing it ignores genuine hardships like high mortality and limited medical knowledge. But understanding how humans lived for two million years illuminates who we are and hints at different ways we might organize our lives and societies in the future.
