Evolution is not necessarily slow. The Russian silver fox domestication experiment produced massive personality changes and even physiological changes in only 20 generations. As for humans, current scientific consensus is that 5000 years ago virtually no human adult could digest milk, and now lactose tolerance is prevalent in like 95% of European-descended people. And none of the above would appear in a visual inspection of a skeleton. I figure the kind of neurological and digestive adaptations to being perma-buzzed might be similar.
