Throughout history they sought new ways of growing and producing foods. Through trial and error they developed different crops, learned how to breed and domesticate a wide range of animals, and found new ways of processing raw foods by bread making, brewing and fermentation. For example: Cheese making

Cheese production uses a biological process of introducing an enzyme from rennet, found in calves' stomachs, into milk, which turns it into solid curds and liquid whey This remains the basis of cheese making today
