Study comparing health and genetic differences in settled and nomadic groups of the #Ariaal of N. #Kenya. A mutation associating to #ADHD may be favourable for the nomads.
'In modern children diagnosed with ADHD, the genetic mutation generally correlates with restlessness and distractibility. And in those Ariaal children who had settled into sedentary Western behaviours, the gene was linked to poor health and distracted classroom behaviours. But in those Ariaal who still practised a traditional nomadic life, the gene mutation was linked to strength and better nutritional health.'
