    I would guess that humans have been around for what, 250k years? And that the vast majority of that didn’t involve a whole lot of milk after age 4.

    So it wouldn’t have been to much advantage to be able to metabolize lactose.

      Keeping Lactase production happened at least twice; north europe and a group in west africa.
