  The earliest traces of human life in the area now known as Argentina are dated from the Paleolithic period, with further traces in the Mesolithic and Neolithic. Until the period of European colonization, Argentina was relatively sparsely populated by a wide number of diverse cultures with different social organizations, which can be divided into three main groups.
  
  The first group are basic hunters and food gatherers without the development of pottery, such as the Selk'nam and Yaghan in the extreme south. The second group are advanced hunters and food gatherers which include the Puelche, Querandí and Serranos in the centre-east; and the Tehuelche in the south—all of them conquered by the Mapuche spreading from Chile —and the Kom and Wichi in the north. The last group are farmers with pottery, such as the Charrúa, Minuane and Guaraní in the northeast, with slash and burn semisedentary existence; the advanced Diaguita sedentary trading culture in the northwest, which was conquered by the Inca Empire around 1480; the Toconoté and Hênîa and Kâmîare in the country's centre, and the Huarpe in the centre-west, a culture that raised llama cattle and was strongly influenced by the Incas.
