In spite of the great difficulty to have to it sums up theory of the origin of the poblamiento of the region, at the present cheats is known in short that the region was populated by bands of Shovel-Indians, hunters and recolectores, these groups specialized in the hunt of big animals, this due to the left archaeological remains.

They have been remains of tips of arrow type "fish line" that would be those you arm but appropriate to give death to these animals, besides being remains of bones gnawed with certain utensils, apparently stone knives. They are also had found leather pieces. These remains that have one date approximate of 10.000 B.P. you they have found in the caves Fell and of the Milodon respectively.

A rain of volcanic ash and the recalentamiento of the area, cause the escape or death massive of the big mammals, these they opened the way to new mammals like those camelidos, these they would have arrived starting from the 6.000 A.P. the archaeological remains have shown the happened changes. Near the old archaeological remains of Fell and Milodón, is the cave Pali - Aike, the remains of this cave show singular and deep differences with the remains of the caves before mentioned, the found arrows they are notoriously different, the material would be of better quality besides having a work more meticulous and a different, almost oval form. These indications would show a new one type of economy. Apart from the before said, I know ago he/she would notice a new form of feeding with the entrance of the marine products, this for the big accumulations of conchales in the breasts Skyring and Otway, besides those left in the channels built by the Fitz-Roy.

The most valuable contribution left by these cultures has been its tombs and its hunt teams
and fishes that have achieved us to transmit their culture.

These groups correspond the Poyas, Puelches and Tehuelches that conformed hunters' bands and recolectores in the whole area of the Patagonia, these bands were not inferior to 20 and non superior to 100 members, what characterizes them as extended families. The favorite preys of these tribes were the mammals, besides certain shellfish and grasses.
