7.3.4 The Original Affluent Society: Comparing Ancient and Contemporary Foragers

In agricultural and industrial societies, people often assume that gathering-hunting peoples must live a hard life, oppressed by the struggle to find enough food and plagued by malnutrition and poor health. Archaeologists and cultural anthropologists who have studied gathering and hunting groups have found otherwise. Researchers have discovered that gatherer-hunters have stronger bones, lower blood pressure, and less heart disease than neighboring farmers, likely due to the amount of walking they do and the abundance of fruits, nuts, and vegetables in their diets (American Heart Association 2012; University of Cambridge 2014). In his ethnographic work among the Dobe Ju/’hoansi, anthropologist Richard Lee found that they worked on average three to four days a week obtaining food and spent the rest of their time socializing and enjoying life. He described the Dobe Ju/’hoansi as fit, healthy, and free of nutritional deficits (1993). Indeed, some Hadza have remarked that the notion of famine is unknown to their culture. While Harvard economist John Kenneth Galbraith has referred to the wealthy industrial economy of the United States as “the affluent society,” anthropologist Marshall Sahlins describes the gathering and hunting lifestyle as “the original affluent society.”

For some 95 percent of evolutionary history, humans and human ancestors relied on gathering and hunting to make a living. In evolutionary terms, it is only very recently that humans have established other modes of subsistence. Farming was invented around 12,000 years ago, far too recently to have shaped humans’ biological evolution very much. By contrast, hominins were practicing gathering and hunting for more than two million years. If humans have evolved to practice any lifestyle, it would be gathering-hunting. This suggests that humans’ brains and bodies might be best suited to the lifestyle described by ethnographers who study gathering-hunting groups: long walks in nature; a diet of mostly fruits, nuts, and vegetables; and plenty of leisure time to relax and talk. Maybe humanity’s ancestors were as robust and happy in their way of life as many contemporary foragers. Maybe.

The problem with this sort of thinking is that people today really don’t know what life was like for humanity’s gathering-hunting ancestors. The archaeological record of fossils and artifacts can reveal much about the diet and diseases of early hominins, but they tell very little about early social structures and cultural values. Some anthropologists have looked to contemporary gathering and hunting groups to understand the way of life of humanity’s ancestors. Maybe they, like contemporary gatherer-hunter peoples, lived in egalitarian bands with group decision-making and a flexible division of labor based on gender, valuing sharing and deploring stinginess. Certainly, they must have had impressive knowledge of the resources and dangers in their environments.

And yet it is a mistake to view the way of life of contemporary gathering-hunting societies as examples of the way of life of humans’ evolutionary ancestors. Groups such as the Hadza are not frozen in time, practicing a static lifeway of the deep past, but rather constantly changing and innovating, blending new ideas and practices with older ones just as farmers, herders, and industrialists do. Most contemporary gathering-hunting groups have lived side by side with farming and herding groups for centuries, often trading with those groups and even experimenting with their subsistence methods from time to time. Most gatherer-hunters have been forced to relocate to less advantageous lands due to the encroachment of these herders and farmers. The culture of many gatherer-hunter groups has been shaped by their incorporation as marginalized minorities in larger nation-states such as Tanzania. As the way of life of contemporary gatherer-hunters has changed so dramatically just in the past century, it’s difficult to draw firm conclusions about human evolutionary history based on their example.
