It might be an exploratory nomadic hunter-gather society that has predators and enemies day and night.
A study analyzed DNA of Neanderthals along with contemporary and prehistoric humans. They found ADHD associated alleles were on genes essential to development before the stone age, but selective pressure has decreased the frequency since then. PMC7248073
Another study on tribes examined an ADHD gene mutation that affects dopamine receptors. In the nomadic tribe, those with the mutation had better social standing and nourishment. In the sedentary tribe, those with the same mutation were malnourished, distracted, and regarded as unreliable by their peers. PMC2440754
A third study found ADHD participants collected more berries with more exploring. Non-ADHD participants collected less berries, spent more time trying to deplete bushes, with less time exploring. PMC10878810
