Coastal Neolithic Morocco (Morocco_LN)

The Morocco_LN cluster evokes a coastal world in motion. Archaeological data indicates Late Neolithic occupation along Morocco’s Atlantic margin, with named material from sites such as Kelif el Boroud and at least one anonymized inland locality. Radiocarbon-bearing contexts and associated ceramics place human activity in a broad interval between roughly 8400 and 3600 BCE, a span that overlaps long-term transitions from hunter‑gatherer lifeways toward more settled, food-producing economies.

Limited evidence suggests these communities lived at the intersection of local continuity and incoming influences. Lithic traditions and pottery styles show regional variation that archaeologists interpret as both indigenous development and cultural borrowing. In genetic terms, the presence of maternal lineages commonly found in Near Eastern and European Neolithic contexts hints at gene flow across the Mediterranean and along coastal corridors. Yet, with only four ancient genomes available, it is important to treat models of migration and replacement as provisional. Small sample sizes can overrepresent particular family groups or funerary practices.

Viewed cinematically, the emergence of Morocco_LN is the slow carving of human lifeways along the Atlantic — nets mended on pebble beaches, hearth smoke rising over damp fields of cereals — while threads of connection to distant populations were woven into local ancestry. Archaeology and genetics together can outline these threads, but the weave remains only partially visible.

Four ancient genomes represent the Morocco_LN designation. The small sample set (n = 4) requires caution: patterns might reflect local pedigrees rather than population-wide frequencies. Still, the genetic signal is evocative. Maternal lineages are dominated by mtDNA K (observed in three individuals) with a single instance of mtDNA X. On the paternal side, one male carried Y‑DNA haplogroup T.

mtDNA K is widely reported among early farming populations in the Near East and Europe and its presence in multiple Morocco_LN individuals may indicate maternal ancestry components related to Neolithic dispersals or maritime gene flow across the western Mediterranean. Haplogroup X also appears sporadically in ancient and modern populations across Eurasia and North Africa; a single occurrence here is suggestive but not definitive.

Y‑haplogroup T has been associated in other studies with Neolithic and post‑Neolithic movements from the Near East into Mediterranean regions. Its appearance in one Morocco_LN male could reflect a paternal lineage introduced by migrants or long‑distance networks. However, the sample count is below ten, so any inference about population structure or demographic processes is preliminary.

Integrative interpretation: archaeological indicators of Neolithic lifeways combined with mtDNA K and Y‑T presence are consistent with some degree of incoming farmer‑related ancestry mixing with autochthonous North African elements. Yet quantifying proportions and directionality will require far greater ancient DNA sampling across Morocco and neighboring regions.
