To increase the amount of a crop that can be grown, it is necessary to prepare the soil to maximize aeration and nutrient dispersion. Before 3000 BCE, this tilling of the land was done by hand, with a form of pick or hoe. The Chinese, however, discovered that a fixed blade could be attached to a frame, and pulled through the earth, allowing a much greater area of land to be cultivated for significantly less effort and time. Initially, plows were pulled by farmers, but, thanks to the domestication of animals, plows could be harnessed to beasts of burden, greatly reducing the effort needed to farm an area of land and effectively increasing the area of land that a farmer could oversee. This increase, in turn, led to

 In c.130,000 BCE, the northern hemisphere entered the Eemian interglacial period of the most current Ice Age. During this period, the average temperature was as much as two degrees warmer than the modern period. As such, it encouraged the migration of various species, in particular Homo sapiens. More than other Homo species, Homo sapiens demonstrated adaptability and ingenuity. The Eemian period made habitable portions of the world that would have previously not supported human life, and Homo sapiens took advantage of the climate shift. Approximately five thousand years later, a group of hunter-gatherer humans made the journey across central Asia and reached what is today recognized as China. Over the next several tens of thousands of years, these early hunter-gatherers began to establish permanent settlements. With this settlement, the basis for the tribes that became the Chinese was established.
