Processing milk is a digestive change, and one that mammals are all able to do at some point. It’s not a very far leap. Processing water with the sea’s salinity would require changes to how our cells are constructed, or at least would require massive changes to our kidneys. There’s simply no (or not enough) selection advantage for it to have happened. |
