I marvel at so many ancient discoveries, non-obvious questions asked, and experiments.
Yeast and fermentation. Alcohol production.
Hulling wheat and grinding the kernel to make flour.
How heat transforms foods.
“Can I plant these seeds myself and harvest the crops?”
The growth of metallurgy to make crude but more effective farm implements (spin off from weapons)
“I wonder what this tastes like?” and the ensuing knowledge including “Nope. Don’t want to die”, it’s storage and handing down to subsequent generations. How many died as a result of “I wonder if I can eat this”experiments.
Large migrations of people to completely unknown far away places that were not hospitable to their seeds.
The explosion of discoverers taking seeds and plants with them on their voyages and bringing new discoveries home.
