LITHIC PERIOD (12 000 B.C.)
The food was based on the hunting of horses, lazy, deers and South American camels. They also ate in some parts of the coast terrestrial snails.
In the coast the way of life was different from the mountain. Bonavia (1991) says that in spite of the strong rains of the Pleistocene, the coast was dry and arid. This caused the extinction of the mega fauna (mastodons and horses).
In the coast have not been found places older than 10 000 years of antiquity, due that 13 000 years ago, the level of the sea was 50 meters lower than the actual one. The actual level was established 7 000 or 6 000 years ago. This means that the coast was wider and in the supposed of having human groups previous to 10 000 years, these vestiges would be submerged under the sea.
In the desert of Paiján (Chicama Valley), Chauchat found lithic artifacts made in rhyolite and in less proportion quartz. Because of this are soft rocks, it is possible that they have been worked using wooden percutores. It is possible that the paijanense used the stone tips only to fish.
The size of the groups didn't surpass fifty individuals for band.
ARCHAIC PERIOD (6 000 - 1800 B.C.)
It is related with the emergence of the tribe that is a group of bands tied by relationship lines and congregated in a territory. It didn't exist institutionalized power. A “boss” was only a consultant with influence. The tribe was auto regulated and its protection was responsibility of all its members.
In the coast, first appear agriculture and then the sedentism. In the valleys of the Andes (2300-3500 m.a.s.l.) agriculture was discovered before. None cultivated plant is native from the coast; this received plants from the Andes or from the jungle
The principals places of this period are Huaca Prieta (Chicama Valley), Chilca, El Paraiso, Caral and Ventarrón, (valley of Lambayeque) studied at the moment by Ignacio Alva Meneses.

MIDDLE HORIZON (550 B.C.-900 D.C.)
The model culture of this period is Wari. Its city could be considered as an unique example of City in the whole Andean area. This because of its extension (2 000 Ha.), its numerous population (30 000 inhabitants) and its complex internal organization. For Luis G. Lumbreras the Wari culture would have been the direct antecedent of the Incas, contrary to Carlos Ponce Sanguinés that considers to the Tiahuanaco culture.
Other important administrative places were: Pikillacta in Cusco, Wiracochapampa in Huamachuco, Wari Wilca in the mountain of Junín and Cerro Baúl in Moquegua.
