Kelif el Boroud, also known as Kehf el Baroud,[1] is an archaeological site in Morocco. It is located to the south of Rabat, near Dar es Soltan.[2] Human fossils excavated in the area have been radiocarbon-dated to the Late Neolithic, around 3,000 BCE. Ancient DNA analysis of these specimens indicates that they carried the broadly-distributed paternal haplogroup T-M184 as well as the maternal haplogroups K1, T2 and X2, the latter of which were common mtDNA lineages in Neolithic Europe and Anatolia. Additionally, these ancient individuals bore an autochthonous Maghrebi genomic component associated with modern Berbers in the Maghreb, as well as an early European Neolithic component. This altogether indicates that the Late Neolithic Kelif el Boroud inhabitants were ancestral to contemporary populations in the area, but also likely experienced gene flow from Europe. Of the old samples that the Late Neolithic Kelif el Boroud skeletons were compared with, they were closely related to fossils from the Early Neolithic Ifri n'Amr or Moussa site in Morocco. They likewise showed ties with Neolithic and Chalcolithic populations from Anatolia and Europe. These affinities had already been gleaned from similar ceramics that were found at Kelif el Boroud and Andalusian Early Neolithic and Cardial sites, as well as from comparable ivory tools that were excavated in Iberian Neolithic sites.[3]
