# behav: ADHD may have been a feature of nomadic exploration among hunter-gatherer societies

<< All mobile organisms forage for resources, choosing how and when to search for new opportunities by comparing current returns with the average for the environment. In humans, nomadic lifestyles favouring exploration have been associated with genetic mutations implicated in attention deficit hyperactivity disorder (ADHD), inviting the hypothesis that this condition may impact foraging decisions in the general population. >>️

# life: hypothetical 'subtle variations' about three ancient neuro-cognitive models, the nomadic explorer, the nomadic owner, the farmer.

<< Prehistoric humans underwent three major migration events across Eurasia, influencing the genetic diversity of present-day Europe. These include the arrival of hunter-gatherers approximately 45,000 years ago, the expansion of Neolithic farmers from the Middle East around 11,000 years ago, and the rise of animal husbandry when steppe pastoralists migrated from the Pontic Steppe approximately 5,000 years ago. Each of these events represents a crucial period in human history that has shaped the genetic diversity observed in present-day Europe, although specific genetic and demographic details remain poorly characterized. >>️
