ecent fieldwork indicates that the Iberomaurusian culture existed in the region from around the timing of the
Last Glacial Maximum (LGM), at 20,000 BP, until the
Younger Dryas.
[4] The industry is succeeded by the
Capsian culture, which was originally thought to have spread into the Maghreb from the
Near East.
[5] However, later studies suggest that the Iberomaurusian may have been the progenitors of the Capsian.
[6][7]
Although modern populations in the Maghreb speak languages belonging to the
Afro-Asiatic family, which is associated with the Capsian culture, it has been hypothesized that the Capsians' predecessors, the Iberomaurusians, may have spoken a language(s) from a different phylum. This was inferred from the likelihood that the Iberomaurusians existed prior to the advent of the Proto-Afro-Asiatic language, as well as from the presence of what appears to be an older, pre-Afro-Asiatic population substratum in parts of the
Atlas Mountains.
Despite suggestions that this minor element may be related to the Basques of southwestern Europe, there appear to be no vestiges of a Basque linguistic influence in the region.
