What Did Ancient Humans Do All Day?

For most of the 300,000 years our species has existed, there were no jobs, calendars, or alarms. How did ancient humans survive? This video reconstructs a day in the life of our ancestors by looking at the hard evidence: a hillside dig, a roasting pit, a cooked fish, and the flour-grinding stones left behind. We examine the famous 1963 study of hunter-gatherer labor and reveal the second data point that changes the entire answer about how much effort daily survival actually required. Beyond the simple time counts, we look at factors like infant mortality and conflict that shaped the Stone Age experience. By separating archaeological data from modern assumptions, we get a clearer picture of what daily life was really like before the agricultural transition.

A note on the numbers: Lee's first count (about 12 to 19 hours a week) covered finding food only; the later totals in this video (44.5 hours for men, 40.1 for women) added food processing, tool making and housework. Retellings round the first number to 15, 17 or 20. We could not open Lee's own tables, so these totals come from the Wikipedia summary linked above; several of the study details also come from summaries of the papers. The Hadza and Ju/'hoansi are living peoples, not stand-ins for people from hundreds of thousands of years ago. #AncientHumans #Prehistory #Anthropology
