During the Neolithic, the earth's environment became substantially colder.​

The Neolithic period is generally characterized as the time when human societies transitioned from hunting and gathering to agriculture and domestication of animals. This period occurred between 10,000 BCE and 4,500 BCE and was marked by a relatively stable global climate. While there were regional fluctuations in temperature and precipitation, there is no evidence to suggest that the earth's environment became substantially colder during the Neolithic.
