'Haplogroup E1b1b may well have been associated with the earliest development of Neolithic lifestyle and the advent of agriculture, which is so far believed to have arisen in the Fertile Crescent, but could have developed earlier in parts of Northeast Africa now covered by the Sahara desert. Agriculture spread from the Near East to Europe, at first mostly ovicaprid and cattle herders. E1b1b men (accompanied by G2a, J and T men) appear to have been associated at least with the diffusion of Neolithic painted pottery from the Levant to the Balkans (Thessalian Neolithic), and with the Cardium Pottery culture (5000-1500 BCE) in the Western Mediterranean. The only concrete evidence for this at the moment is the presence of the E-V13 subclade, commonest in the southern Balkans today, at a 7000-year old Neolithic site in north-east Spain, which was tested by Lacan et al (2011).
The African origin of some Neolithic cattle was confirmed by Decker et al (2013), who reported that Iberian and Italian cattle possess introgression from African taurine.
Judging from modern frequencies, E1b1b would have been a major Near Eastern haplogroup linked to the propagation of agriculture in Europe. It is the only Near Eastern haplogroup consistently found throughout Europe, even in Norway,"
Note that the "OTHER" possible origin of agriculture is in the Sahara. (!!!!!!!!), which is also the probable origin of the Cushitic peoples.
