In a March 2019 genetic study published in "[[Science (journal)|Science]]", three Celtiberians buried at [[La Hoya, Salamanca]] between 400 BC and 195 BC were examined. They had high levels of [[Northern Europe|north]]-[[Central Europe|central European]] ancestry compared to non-Celtic populations of Iberia. One of the males examined was found to be a carrier of the paternal [[Haplogroup I-M438|haplogroup I2a1a1a]].
