maybe is not paleolithic, but neolithic something beetween maybe is of Iberomaurisian origin
According to A.F. Pardiñas it would have arrived in Iberia in Late Mesolithic / Early Neolithic times:
The L3f variant found in Asturias seems to constitute an Iberian-specific haplogroup, distantly related to lineages in Northern Africa and with a deep ancestry in Western Africa. Coalescent algorithms estimate the minimum arrival time as 8,000 years ago, and a possible route through the Gibraltar Strait.
It doesn't seem to be Iberomaurisian proper but of remote Western African origin since L3f1b is hardly found in NW Africa but is very frequent in Western Africa. Probably it reached NW Africa from W Africa in the times of Green Sahara and then several millenia later it reached Iberia.
