But I've always thought that it requires many thousands
of years before we adapt to "new" food. Or is milk one of those
"easy" adaptations (through neoteny) that require much less time?
Even so, would 1000-odd years really be enough for a population to
adapt? It would be nice if there were any convincing evidence
that humans have adapted to milk (someone mentioned buffalo milk for Asians)
since I'm starting to really miss milk products.
