Since the genesis of agriculture, humans have always had a significant incentive to increase the yields of our organic products through whatever means available to us. This incentive has remained a constant motivation for the last 10,00 years. The invention of farming was the result of the increased pressure on humans due to a change in the weather caused by a small ice age which made hunting and gathering much more difficult. Farming presented an option that demanded an increase in work in exchange for a predictable supply of food, something that was not easily attained at the time. Ancient humans chose farming over their more leisurely hunter-gatherer lifestyle, a decision which had profound effects on the crops being farmed, these effects can be exemplified by cereal crops such as wheat and barley in what is now known as the fertile crescent in the Levant Region. Early farmers would only plant crops that were easy to harvest, sometimes bringing them from quite far away to accidentally create the first domestic variety of wheat and barley. Unlike their wild counterparts, these plants didn’t drop their grain which made them much easier to harvest. Cutting grain filled stocks is much easier than picking grains from the dirt. Farming of any kind often results in a product that is more fruitful for the cultivator due to its success as a organism being reliant on its survival in an artificial environment. The more it is farmed the better it gets at being harvested and planted. This change, previously only possible through natural process, was enacted through the first instance of artificial selection, the precursor to modern day genetic modification.Farming was independently discovered and employed 2,000 years later in China with the domestication of rice making the grains larger, and easier to store, Africa, with the domestication of pearl millet making the grains stick to the stem instead of dispersing similar to wild wheat or rye, Mexico, with the domestication of maize again preventing the dispersion of the corns, and The Andes, with the domestication of the common bean making them larger with a thinner coat followed suit soon after. Agriculture technology continued to evolve in other ways as well, for example humans learned that planting and harvesting at certain times yielded much greater rewards. As farming became increasingly productive and globally recognized as more efficient than hunting and gathering, society shifted to accommodate it leading to massive reforms. Accountability for crops and herds influenced human behavior as people were now required to look after them, making humans more sedentary than ever before allowing them to have more children than any other human society to date. Societies began to recognize personal property, become tied to territory which allowed for greater accumulation of personal belongings and view land as intrinsically valuable due to its potential for farming. Cities could begin to realistically develop and the first official societies rose along the banks of rivers such as the Nile.As food becomes increasingly available, population increases leading to a higher demand for food, spurring agricultural technological advance. An increased population not only motivates the development of ingenious methods for attaining food, but also has a higher capacity for technological advance. Technological advance allows for population growth by increasing the efficiency of an existing population creating a surplus.
