on the car ride into work today I thought to myself " like how did humans figure out how to bake? or make wine? like who added yeast to liquid and let it ferment and was like 'if we wait long enough, this stuff will taste gross and make us sick, but it'll be cool bro trust me'? and did the guy add several other ingredients to several other batches and yeast+grapejuice was the most popular?" I'm just curious as to how humans discovered certain things. Is it all serendipitous? Trial and error? Pseudoscience that worked?
