It has been considered that the Lucana-andamarcas, extended their dominions in the field of agriculture, with the product culture of Andean valleys (maize). While wancas by its geographic location has maintained the development cattle (it calls), adding like the activities potters and textileros.. (Similarly see: CBS).
