Stephen Oppenheimer has proposed that from c.16,000BC, the warmer climate allowed the expansion of proto-Basque groups to
Britain and Ireland, and that today's inhabitants of Britain and Ireland descend from the Basques. In 2008, the
Finnish linguist
Kalevi Wiik proposed that the current Basque language is the remainder of a group of "Basque languages" that were spoken in the Paleolithic throughout western Europe and that retreated with the progress of the Indo-European languages. Wiik states that his theory coincides with the homogeneous distribution of the
Haplogroup R1b in
Atlantic Europe. Ludomir R. Lozny states that "Wiik's controversial ideas are rejected by the majority of the scholarly community, but they have attracted the enormous interest of a wider audience."
Paleogenetic investigations In May 2012, the
National Geographic Society Genographic Project released a study that showed through detailed DNA analysis of samples from French and Spanish Basque regions that Basques share unique genetic patterns that distinguish them from the surrounding non-Basque populations. The results of the study clearly support the hypothesis of a partial genetic continuity of contemporary Basques with the preceding Paleolithic/Mesolithic settlers of their homeland.
Paleogenetic investigations by the
Complutense University of Madrid indicate that the Basque people have a genetic profile coincident with the rest of the European population and that goes back to Prehistoric times. The
haplotype of the
mitochondrial DNA known as
U5 entered in Europe during the
Upper Paleolithic and developed varieties as the
U8a, native of the
Basque Country, which is considered to be Prehistoric, and as the
J group, which is also frequent in the Basque population. about mitochondrial

Alava, note that there are no differences between these remains and others found across
Atlantic Europe. Studies based on the
Y chromosome genetically relate the Basques with the
Celtic Welsh, and

Stephen Oppenheimer from the
University of Oxford says that the current inhabitants of the
British Isles have their origin in the Basque refuge during the last
Ice age. Oppenheimer reached this conclusion through the study of correspondences in the frequencies of genetic markers between various European regions. The
haplogroup R1b, can be found most frequently in the
Basque Country (91%),
Wales (89%) and
Ireland (81%). In 2015, a new scientific study of Basque DNA was published which seems to indicate that Basques are descendants of Neolithic farmers who mixed with local hunters before becoming genetically isolated from the rest of Europe for millennia. Mattias Jakobsson from Uppsala University in Sweden analysed genetic material from eight Stone Age human skeletons found in El Portalón Cavern in
Atapuerca, northern Spain. These individuals lived between 3,500 and 5,500 years ago, after the transition to farming in southwest Europe. The results show that these early Iberian farmers are the closest ancestors to present-day Basques. The official findings were published in
Proceedings of the National Academy of Sciences of the United States of America. "Our results show that the Basques trace their ancestry to early farming groups from Iberia, which contradicts previous views of them being a remnant population that trace their ancestry to Mesolithic hunter-gatherer groups," says Prof. Jakobsson. However, the results also showed that Basques, along with many other Iberian groups, carry both Neolithic farmer ancestry as well as some local mesolithic hunter-gatherer ancestry; showing that "the incoming farmers admixed with local, Iberian hunter-gather groups, a process that continued for at least 2 millennia." Rather, some 4500 years ago almost all Y-DNA heritage from Iberian admixture of Mesolithic hunter-gatherers and Neolithic farmers was replaced by the lineage of Indo-European herders from the steppe, and the Basque genetic distinctiveness is a result of centuries of low population size, genetic drift, and
endogamy. One implication of these hypothetical and controversial etymologies was that some aspects of the Basque language had been stable and uninfluenced by other languages since the
Stone Age. However, these etymologies are now doubted by mainstream vasconists. has been identified as a loan from the
