Ther’s an old saying:
Brave was he who first ate an oyster...................
Overcoming Hydrophobia. But I think these common assumptions about early man are wrong. I don’t think we give them enough credit and they did not fear water at all. I think they were floating a long time before we think they were.
I eat a LOT of smoked oysters; they are relatively cheap, filling little protein bombs for a low carb diet, but yes, I often wonder about how they came to be part of the human diet. First, to the casual observer, they look like an underwater rock. You have to crack them open to see what’s inside. Presumably some early human noticed some other creature cracking them open to eat them, and figured they’d give it a try.
Another old saying:
“Hunger is the best sauce.”
