In a recent genetic study by Semino et al. (2004), the [[Haplogroup J-M267|Haplogroup J1]] associated with the diffusion of Arabs was found at 35% in [[Algeria]],<ref>{{Cite journal |last1=Semino |first1=Ornella |last2=Magri |first2=Chiara |last3=Benuzzi |first3=Giorgia |last4=Lin |first4=Alice A. |last5=Al-Zahery |first5=Nadia |last6=Battaglia |first6=Vincenza |last7=Maccioni |first7=Liliana |last8=Triantaphyllidis |first8=Costas |last9=Shen |first9=Peidong |last10=Oefner |first10=Peter J. |last11=Zhivotovsky |first11=Lev A. |last12=King |first12=Roy |last13=Torroni |first13=Antonio |last14=Cavalli-Sforza |first14=L.

Recent studies on the common J1 Y chromosome suggest it arrived over 10,000 years ago in North Africa, and M81/E3b2 is a Y chromosome specific to North African ancestry, dating to the [[Neolithic]]. A thorough study by Arredi et al. (2004) which analyzed populations from Algeria concludes that the North African pattern of Y-chromosomal variation (including both E3b2 and J haplogroups is largely of Neolithic origin, which suggests that the Neolithic transition in this part of the world was accompanied by demic diffusion of Afro-Asiatic–speaking pastoralists from the [[Middle East]]. This Neolithic origin was later confirmed by Myles et al. (2005) which suggest that "contemporary Berber populations possess the genetic signature of a past migration of pastoralists from the Middle East", although later papers have suggested that this date could have been as longas ten thousand years ago, with the transition from the Oranian to the Capsian culture in North Africa.<ref>{{cite journal | url=https://doi.org/10.1007%2Fs00439-005-1266-3 | doi=10.1007/s00439-005-1266-3 | title=Genetic evidence in support of a shared Eurasian-North African dairying origin | year=2005 | last1=Myles | first1=Sean | last2=Bouzekri | first2=Nourdine | last3=Haverfield | first3=Eden | last4=Cherkaoui | first4=Mohamed | last5=Dugoujon | first5=Jean-Michel | last6=Ward | first6=Ryk | journal=Human Genetics | volume=117 | issue=1 | pages=34–42 | pmid=15806398 | s2cid=23939065 }}</ref>
