But if we look on other parts of our bodies where we don't directly interact with the environment -- our kidneys, our livers, our hearts -- there is no way to say, by just looking at these organs, where in the world they would come from.
Bet ja mēs apskatām citas mūsu ķermeņa daļas, ar kurām mēs tieši nesaskaramies ar vidi -- mūsu nieres, mūsu aknas, mūsu sirdis -- nav veida kā pateikt, tikai paskatoties uz šiem orgāniem, no kurienes pasaulē tie varētu nākt.
