I've had a longterm habit of reading some pretty diverse subjects with new scientific theories being pretty high on the list of general interests. Today I found a positive article about ADHD I think is worth sharing since many of my friends have carried around the label as well as medication for a condition I think is essentially a normal part of being human. The article pretty much confirms my feeling that there's a benefit to being able to focus lightly on multiple subjects rather than just one thing at a time. Here it is for you to decide for yourself:
A genetic propensity for attention deficit hyperactivity disorder may actually help people thrive in nomadic environments, says a study of Kenyan tribesmen.
U.S. researchers found that a gene associated with the disorder was linked to better health and body weight in a group of nomadic cattle herders, but could cause malnourishment in their cousins who have recently settled and begun to grow crops.
"Our findings suggest that some of the variety of personalities we see in people is evolutionarily helpful or detrimental, depending on the context," said lead author Dan Eisenberg, an anthropologist at Northwestern University in Chicago, Illinois.
"This insight might allow us to begin to view ADHD as not just a disease but something with adaptive components," he said.
The effects of these genes have been studied in industrial countries but little research has been carried out in subsistence environments which more closely mirror the environments where much of human genetic evolution took place.
"It is possible that in a nomadic setting, a boy with this allele might be able to more effectively defend livestock against raiders or locate food and water sources, but that the same tendencies might not be as beneficial in settled pursuits such as focusing in school, farming or selling goods," Eisenberg said.
The study was published in the journal BMC Evolutionary Biology. Now all we have to do is become nomads and we'll all be perfectly normal.
By the way this is one of my very first silk paintings and what I lacked in skill I certainly made up for in enthusiasm.
