Do you think that Ligurians may have the same origins as iberians?
This would explain the fact that northern italians cluster closer with iberians, due to Ligurian and gaulish admixture versus iberians and celtiberians adimxture.

Ligurian origins
In the 19th century, the Ligures' question got the attentions of not a few scholars. Amédée Thierry, a French historian, linked them to the Iberians,[6] while Karl Müllenhoff, professor of Germanic antiquities at the Universities of Kiel and Berlin, studying the sources of the Ora maritima by Avienus (a Latin poet who lived in the 4th century AD, but who used as source for his own work a Phoenician Periplum of the 6th century BC),[7] held that the name Ligurians generically referred to various peoples who lived in Western Europe, including the Celts, but thought the real Ligurians were a Pre-Indo-European population.[8]
Dominique-François-Louis Roget, Baron de Belloguet, claimed a "Gallic" origin.[9]
In favor of a Pre-Indo-European origin thesis were Henri d'Arbois de Jubainville, 19th-century French historian, who argued that the Ligurians, together with the Iberians, constituted the remains of the native population that had spread in Western Europe with the Cardium Pottery culture cardial ceramic,[10] and Arturo Issel, a Genoese geologist and paleontologist, who considered them direct descendants of the Cro-Magnon men that lived throughout Gaul from the Mesolithic.[11]
