To give a detailed chronological order of these cultures would be a difficulta task, since none of them had a written language. All the information has been obtained from archaelogical excavations. In addition one culture succeded another, bringing its own values, as the Spanish did when they conquered the Inca Empire. The only difference is that the Spaniards left written records. Peru is unique in South America for its archaelogical wealth.
Travellers enjoy visiting centuries-old ruins.
The ceramics and textiles that these cultures left behind are one of the most important sources of information about the pre-Columbian inhabitants. You can see these relics in Peru's museums. They lived in caves. Until almost 4000 BC, cultural development consisted only of stone implements for hunting. They learned how to make fires, they wore animal skins, and made simple tools and weapons mostly from stone and bones.
