Cuanfo hablamos de la periodizacion cual es el inicio, decelace , final de era y actual​

¡Traduce del inglés al español! También lamento haber entendido mal la pregunta. En mi escuela secundaria y no estamos aprendiendo eso.

The Holocene period, which began 11,700 years ago following the last big ice age, is the official name for the 'age' we are currently in. All periodization methods are more or less arbitrary to the extent that history is continuous and not generalized. Past time would be nothing more than a jumble of events without a framework to help us understand them if there were no defined periods, no matter how clumsy or imprecise they were. Nations, nations, families, and even individuals are continuously imposing overlapping schemes of historical periodization, each with their own remembered history.
