Claim: Biscay was severely affected by the changes brought by the advances of agricultural cultivation and domestication of sheep and megalithism arrived together with the Neolithic technologies.
Evidence: While the first evidences of Neolithic contact in the Basque Country can be dated to the 4th millennium BCE, it was not until the beginning of the 3rd that the area accepted, gradually and without radical changes, the advances of agricultural cultivation and domestication of sheep. Biscay was not particularly affected by this change and only three sites can be mentioned for this period: Arenaza, Santimamiñe and Kobeaga (Ea) and the advances adopted seem limited initially to sheep, domestic goats and very scarce pottery.
