[Jingle Bell]

First, The Iberians IA (Non Celts like Tartessians) plost with Basque bcs they had a low steppe (10% - 20%) high WHG (15% - 25%) and none Taforalt (Which is present in Iberian since Roman Times)
The Celtiberians (As the names sugest) were a mix of the iberians and the celts (these celts were related to gauls) they dont plot with ppl from Uk bcs the islanders celts were celtized Bell Beakers (mostly bbc with some celt dna) the islanders celts werent celts proper, and the mix with the iberians made they more North shifted than the Pre-Celts Iberians but more South Shifted than the Gauls and La Tene

and modern iberians are more north shifted than the celtiberians bcs modern iberians descends mostly from the Northern conquerors who were heavily Western-HispanoKelts (Also the "purest" celts since they dont mix with the natives) + some Germanic influence (but we know little abt this moment, we lack of samples so its hard know)

Modern Iberians are aorund 75% IA Iberians and the rest its mainly Germanic, roman, NA and Levantine
