What Did Ancient Humans Do All Day?

What Did Ancient Humans Do All Day? What did ancient humans do all day, and did hunter-gatherers really work only 15 or 20 hours a week? We rebuild one ancient day in five measured numbers, from a 1964 work diary in the Kalahari to ice age footprints in New Mexico. 📝 ABOUT THIS VIDEO: You have probably seen the meme: cavemen barely worked. The number behind it is real. It comes from a work diary kept by the anthropologist Richard Lee at a camp in the Kalahari Desert. But what exactly did that number count, and what did it leave out? We follow one day through five numbers: the famous work-hours tally, how often hunters come home with an animal, how many hours foragers spend sitting, a nearly mile-long walk preserved in mud at White Sands National Park, and a fifth number about chewing that changes the meaning of the whole question. Along the way we test the "original affluent society," the "Man the Hunter" picture, and the recent debate over how often women hunted. How many hours did hunter-gatherers work? Did prehistoric people sleep more than we do? Every claim is rated on the certainty gauge: measured, debated or just a guess. 📚 RESEARCH & SOURCES: ▸ Lee's work diary — Richard B. Lee, "What Hunters Do for a Living" (1968) and The !Kung San (1979, Cambridge University Press) — about 2.4 days a week of food-getting at Dobe in 1964; about 40 to 44.5 hours a week with chores. ▸ The original affluent society — Marshall Sahlins, Man the Hunter symposium (University of Chicago, 1966); Stone Age Economics (1972). ▸ Re-reading the numbers — David Kaplan, "The Darker Side of the Original Affluent Society" (2000) — includes the 1948 Arnhem Land records of McCarthy and McArthur. ▸ Man the Hunter and its critics — Lee and DeVore, eds., Man the Hunter (1968); the critique by Jane Collier and Michelle Rosaldo; Frances Dahlberg, ed., Woman the Gatherer (1981). ▸ Hadza life — Frank Marlowe, The Hadza (2010, University of California Press). ▸ Hadza hunting — Hawkes, O'Connell and Blurton Jones (1991) — a large animal on about 1 hunter-day in 30. ▸ Hadza activity — Raichlen et al. (2017, American Journal of Human Biology) — about 135 minutes a day of moderate to vigorous activity. ▸ Walking and energy — Pontzer et al., "Hunter-Gatherer Energetics and Human Obesity" (2012, PLOS ONE) https://doi.org/10.1371/journal.pone.... — men walked about 7 miles a day, women about 3.5. ▸ Sitting and squatting — Raichlen et al. (2020, PNAS) https://doi.org/10.1073/pnas.1911868117 — about 9.9 resting hours a day, much of it squatting or kneeling. ▸ Sleep — Yetish et al., "Natural sleep and its seasonal variations in three pre-industrial societies" (2015, Current Biology) — 5.7 to 7.1 hours a night. ▸ Women and hunting — Anderson et al. (2023, PLOS ONE); Venkataraman et al. (2024, Evolution and Human Behavior). ▸ White Sands trackway — Bennett, Reynolds and colleagues, "A tale of two trackways" (2020, Quaternary Science Reviews) — a walker carrying a toddler for close to a mile. ▸ Older White Sands prints — Bennett et al. (2021, Science); Pigati et al. (2023, Science); Holliday et al. (2025, Science Advances) — the dates are still debated. ▸ Time spent eating — Organ, Nunn, Machanda and Wrangham (2011, PNAS) — predicted 48% of daily activity, observed 4.7%. ▸ Cooking and fire — Richard Wrangham, Catching Fire (2009); Berna et al. on Wonderwerk Cave (2012, PNAS). ▸ Farming and leisure — Dyble et al. (2019, Nature Human Behaviour) — about 10 more hours of work a week where the Agta farmed most. ▸ American Time Use Survey — US Bureau of Labor Statistics, released June 2026 — about 5.2 hours of leisure a day. ———————————————————— PEOPLE & PLACES IN THIS VIDEO: ▸ Dobe, Kalahari Desert — the Ju/'hoansi camp near the Botswana-Namibia border where Richard Lee kept his 1964 diary. ▸ The Hadza — about 1,200 people near Lake Eyasi, Tanzania, about a third of whom still forage for most of their food. ▸ The Agta — a people of the northern Philippines, some foraging and some farming. ▸ White Sands National Park, New Mexico — home to the largest known collection of fossilized human footprints, according to the National Park Service, on the shore of a vanished ice age lake. ———————————————————— #prehistory #evolution #archaeology #huntergatherers #ancienthumans
