I know in a pinch people could maybe tolerate small amounts of saltwater, but if I’m not mistaken, I’m pretty sure you can’t survive off it alone, and so…How’d that happen?
It seems kind of bizarre, but I guess the further inland people went the more advantageous it was to shed any such capacity to process saltwater?
Same here! Glad you asked tbh, as I was also curious about the broader question but felt it might be easier to keep it narrow.
