Lessons from fishermen and foragers
Anthropologist David Samson revealed that human sleep patterns have evolved from those of their ancestors, becoming shorter, deeper, and more flexible. This evolution has allowed humans more time for tool use, social interaction, and migration. He explained that humans sleep about seven hours a day, which is less than the 10.5 hours predicted by earlier models. Additionally, humans spend a higher proportion of their sleep in REM sleep compared to other primates, a factor that promotes creativity and innovation in human development. Samson studied how reduced sleep duration and increased flexibility in sleep patterns have contributed to human survival and evolution, focusing on how social environment and security have influenced sleep habits throughout history.
