Bølling-Allerød
The Bølling-Allerød interstadial was a warm and moist interstadial period that occurred during the final stages of the last glacial period. This warm period ran from c. 14,700 to 12,700 years before the present. It began with the end of the cold period known as the Oldest Dryas, and ended abruptly with the onset of the Younger Dryas, a cold period that reduced temperatures back to near-glacial levels within a decade.
In some regions, a cold period known as the Older Dryas can be detected in the middle of the Bølling-Allerød interstadial. In these regions the period is divided into the Bølling oscillation, which peaked around 14,500 BCE, and the Allerød oscillation, which peaked closer to 13,000 BCE.
==Human cultures==
Humans reentered the forests of Europe in search of big game, which they were beginning to hunt relentlessly, many to extinction. Their cultures were the last of the Late Upper Palaeolithic. Magdalenian hunters moved up the Loire into the Paris Basin. In the drainage basin of the Dordogne, the Perigordian prevailed. The Epigravettian dominated Italy. In the north, the Hamburgian and Federmesser cultures are found. The Lyngby, Bromme, Ahrensburg and Swiderian were also attested in Europe at this time. To the south and far east the Neolithic had already begun. In the middle east, the pre-agricultural Natufian settled around the east coast of the Mediterranean to exploit wild cereals, such as emmer and two-row barley. In the Allerød they would begin to domesticate these plants.
