[7] Beaker finds have been found at about seventy sites in Sardinia; they are concentrated mostly along the western coast of the island, from the Nurra region to Sulcis-Iglesiente, and in Campidano, with some settlement in the east, in Dorgali and in the Sarrabus.
This could mean that the Beaker bearers were nomadic people dwelling in tents [10] or caves[9] that depended mainly on the cultivation of wheat and the raising of sheep and goats (diet, as in Great Britain, was characterized by a high intake of animal proteins[11]).
One must think that the introduction of the Bell Beaker culture was due to the arrival of a new ethnic group which, although numerically a minority, brought profound changes in the political, economic and religious reality of the island.
The new men who came from the sea are linked to pastoral experiences, they bring with them a lunar cult and they try to impose, partially succeeding, their patriarchal and at the same time hierarchical conception of societyAnthropological studies have shown that the Beakers were of a different physical type (shortheads) to the previous inhabitants of the island (longheads).
[15] At Anghelu Ruju, the height of the individuals of the Beaker and Bonnanaro cultures ranged from 1.42 m to 1.72 m.[16] A preliminary survey of the deceased at the hypogean-megalithic tomb of Pranu Siara (Suelli) has shown that they were characterized by robustness and tall stature.
