The Holocene /ËhÉlÉµsiËn/ is the geological epoch that began after the Pleistocene at approximately 11,700 years BP and continues to the present. The Holocene is part of the Quaternary period. Its name comes from the Greek words á½Î»Î¿Ï (holos, whole or entire) and ÎºÎ±Î¹Î½ÏÏ (kainos, new), meaning entirely recent. It has been identified with the current warm period, known as MIS 1, and can be considered an interglacial in the current ice age based on that evidence.
