Mechta-Afalou

Mechta skull excavated at Constantine, Algeria.

Mechta-Afalou (Mechtoid) are a population that inhabited parts of North Africa during the late Paleolithic and Mesolithic. They are associated with the Iberomaurusian archaeological culture.

Mechtoids are believed to have been assimilated during the Neolithic and early Bronze Age by the makers of the ensuing Capsian culture.[1] Craniometric analysis indicates that these Iberomaurusians were closely related to the early Holocene Capsians of the Maghreb (Tamazgha), as well as the early Holocene Kiffians of the Sahara.[2]

Iberomaurusian fossils excavated at the Afalou site were found to carry the mtDNA haplogroups H or U (3/9; 33%), J (2/9; 22%), H103 (1/9; 11%), H14b1 or JT (1/9; 11%), R0a1a (1/9; 11%), and T2b (1/9; 11%).[3] All of these are Eurasian Haplogroups.

Iberomaurusian fossils excavated at the Ifri N'Ammar site were found to carry the Y-DNA haplogroups E-M35*(1/2; 50%) and E-L19*(1/2; 50%). All individuals carried the mtDNA haplogroup U6.[4]

Iberomaurusian fossils excavated at the Taforalt site were found to carry the Y-DNA haplogroups E-M78*(4/6; 66%), E-L618*(1/6; 16%), and E-M215*(1/6; 16%). All individuals carried the mtDNA haplogroups U6(6/7; 85%) and M1(1/7; 14%).[5]
