Nikolay [14]

La respuesta correcta para esta pregunta abierta es la siguiente.

Las etapas de la prehistoria básicamente son:

La Edad de Piedra. Durante esta época hace muchos miles d años, los primeros humanos comenzaron a realizar algunas actividades con el apoyo de las piedras, como objetos y utensilios para abrir o romper cosas.

Las divisiones de esta etapa son el Paleolítico, Mesolítico y el Neolítico-

La Edad de los Metales. Durante esta época, los humanos empiezan a descubrir cómo trabajar con ciertos metales. Hacen a un lado las piedras y se sirven de los metales para avanzar. En esta etapa también comienza la formación de las primeras civilizaciones.

Luego ya vienen la  Edad Antigua y grandes civilizaciones, la Edad Media y las grandes monarquía Europeas y los señores feudales. Aquí también se incluye la era de la Exploración y el descubrimiento de América, el Renacimiento y la Ilustración.  

Luego viene la edad moderna de los 1700s hasta nuestra época actual.
