Is ADHD an advantage for Nomads?

Here’s a link to a Press Release ‘Is ADHD an advantage in early Tribesman?’

The researchers analysed how body mass and height correlated with alleles of the DRD4 gene in the Kenyan Ariaal, traditionally nomadic tribespeople. They found that the DRD4 7 rpt allele (one of the genes linked to adhd) was associated with better nourished nomads, but that Ariaal with this gene and living a modern lifestyle- were malnourished compared with carriers of other versions of DRD4, evidence that the impact of ADHD can be positive or negative , depending on the environment?
