Climate change therefore the emergence of agriculture
The first known examples of animal domestication occurred in western Asia between 11,000 and 9,500 years ago when goats and sheep were first herded, whereas samples of plant domestication time to 9,000 years ago when wheat, lentils, rye, and barley were first cultivated. This period of technological boost took place within a time of climatic transition that followed the final glacial period. A number of researchers have suggested that, although weather change imposed stresses on hunter-gatherer-forager societies by causing quick shifts in resources, in addition offered options as brand- new plant and animal resources made an appearance.
Glacial and interglacial cycles of this Pleistocene
The glacial period that peaked 21,500 years ago was only the most up-to-date of five glacial durations within the last few 450,000 years. In fact, the planet earth system features alternated between glacial and interglacial regimes for over two million years, a period known as the Pleistocene. The period and seriousness of this glacial durations increased in those times, with a specially sharp change occurring between 900,000 and 600,000 years ago. Earth is currently inside the newest interglacial period, which started 11,700 years ago and is popularly known as the Holocene Epoch.
The continental glaciations of the Pleistocene left signatures regarding the landscape in the shape of glacial deposits and landforms; nonetheless, the most readily useful knowledge of this magnitude and timing of the various glacial and interglacial durations arises from oxygen isotope files in ocean sediments.
