Ifri N'Ammar or Ifri n'Amru Moussa is an Aterian and Iberomaurusian archaeological site in Morocco located on Zemmour Plateau in the rural commune of Ait Siberne (province of Khemisset), along the national road number 6 which leads to Meknes.
Human fossils excavated in the area have been radiocarbon-dated to the Early Neolithic, around 5,000 BCE. Ancient DNA analysis of these specimens indicates that they carried paternal haplotypes related to the E1b1b1b1a (E-M81) subclade and the maternal haplogroups U6a and M1, all of which are frequent among present-day communities in the Tamazgha. These ancient individuals also bore an autochthonous North African genomic component that peaks among modern Berbers, indicating that they were ancestral to populations in the area. Of the old samples that the Early Neolithic Ifri n'Amr or Moussa skeletons were compared with, they were most closely related to fossils from the Late Neolithic Kelif el Boroud site near Rabat. They likewise showed ties with ancient specimens from the Mesolithic Natufian and Pre-Pottery Neolithic cultures of the Levant. The genomic composition of Ifri Amr U Mussa individuals was similar to the Later Stone Age samples from Taforalt and indicates a genetic continuity in North Africa since Paleolithic to Early Neolithic.
