Lactose intolerance down to a single gene, it’s the original “state” of the human digestive system, which was never really supposed to digest milk products after infancy. Amazingly though, just as people started farming animals for dairy, the “disease” of lactose tolerance began spreading as it conferred survivability on people. Apparently in Europe, French people fart the most when drinking milk.
