Origin of the Basques

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.[4]

Paleogenetic investigations by the Complutense University of Madrid[5] indicate that the Basque people have a genetic profile coincident with the rest of the European population and that goes back to Prehistoric times.[6] The haplotype of the mitochondrial DNA known as U5 entered in Europe during the Upper Paleolithic[7] and developed varieties as the U8a, native of the Basque Country, which is considered to be Prehistoric,[8] and as the J group, which is also frequent in the Basque population.[8] The works of Alzualde A, Izagirre N, Alonso S, Alonso A, de la Rua C.[9] about mitochondrial DNA of the Human remains found in the Prehistoric graveyard of Alaieta, in 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 Irish;[10] 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.[11][12][13][14] The haplogroup R1b,[15] can be found most frequently in the Basque Country (91%), Wales (89%) and Ireland (81%).[11] The age of subclade which Basque carry, Haplogroup R1b-DF27, "is estimated at ~4,200 years ago, at the transition between the Neolithic and the Bronze Age, when the Y chromosome landscape of Western Europe was thoroughly remodeled. In spite of its high frequency in Basques, Y-STR internal diversity of R1b-DF27 is lower there, and results in more recent age estimates", implying it was brought to the region from elsewhere.[16]

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.[17] 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.[18] The official findings were published in Proceedings of the National Academy of Sciences of the United States of America.[19] "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."[20]

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,[21][22] and the Basque genetic distinctiveness is a result of centuries of low population size, genetic drift, and endogamy.[23] In 2019, a study was published in Science in which a more fine-tuned and deep time-transect of Iberian ancient populations including the Basque were analyzed. From their abstract, it says: "and we reveal that present-day Basques are best described as a typical Iron Age population without the admixture events that later affected the rest of Iberia." This indicates Basques were isolated from admixture with outside groups since at least 1000BC or 3000 years before the present. In Iberia, these later admixture (interbreeding) events were with central European (Celtic), eastern Mediterranean and northern African populations, and genomic ancestry from them are found in all or most present-day Iberian populations, except for the Basque.[24]

In the field of linguistics, there are two lines of investigation, both based on etymology; one on toponyms, not only in the Basque Country but also in the rest of the Iberian Peninsula and Europe, and the other on the etymology of Basque words.

Some vasconists have, in the past, suggested that Basque may have several words, all related to tools, that are derived from a word for "stone", haitz (though this primarily means "rock, boulder" in modern Basque). These include:

• (h)aizkora "axe"
• (h)aitzur "hoe"
• (h)aitzur "shears"
• (h)aiztur "tongs"
• aizto "knife"

Theories regarding the possibility of such a shared root have been put forward by Louis Lucien Bonaparte, Miguel de Unamuno, Julio Caro Baroja and others.[25] One inference 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. Aizkora has been identified as a loan from the Latin asciola.[26] The root of the remaining terms – based on the Roncalese dialect, which is known for its preservation of historical nasals and has the documented forms antzur, ainzter, aintzur and ainzto – was ainz- and thus the reconstructed root was *ani(t)z or *ane(t)z. There are no traces of such a nasal sound in the word haitz "rock" (cf. Roncalese aitz).[25]

The theory of the Basque-Iberism claims that there is a direct relationship between the Basque language and the Iberian language, meaning either that Basque evolved out of the Iberian language, or that its precursor belonged to the same language family. The first author to suggest this theory was Strabo in the 1st century BC (at a time when the Iberian language was still spoken); he asserted that the Iberians and the Aquitanians were similar physically and that they spoke similar languages and had similar customs.

The German linguist Wilhelm von Humboldt proposed, in the early 19th Century, a thesis in which he stated that the Basque people were Iberians, following some studies that he had conducted.

Others claim there is not a direct connection, including Koldo Mitxelena who claims the similarities between Iberian and Basque are attributed solely to the relationship of vicinity, and not to any kinship.[27][28]

Some researchers have propounded the similarities between the Basque language and the Caucasian languages, especially the Georgian language.

The comparison between the matrilineal and patrilineal DNA of the native peoples from the Basque Country and Georgia has allowed the discovery of significant differences. The hypothesis that related both populations is only based on the typological similarities, which is not an accepted marker of linguistic kinship. These superficial similarities in the linguistic typologies do not seem to accompany a genetic relation at a population level.[29] The possible relation between Basque and the languages of the Caucasus is denied by authors such as Larry Trask, who stated that the comparisons were wrongly made, given the fact that the Basque language was compared with several Caucasian languages at the same time.

These theories are based on the Old European hydronymy, assuming that the first inhabitants of Europe spoke a common tongue[30] or languages of the same language family. This theory is not accepted by most linguists, who believe that, in a territory as large as Europe, more than one language had to be spoken.[30]

In January 2003, the Spanish edition of the popular science magazine Scientific American published a study conducted by Theo Vennemann,[31] where he concluded:

Much of the names of settlements, rivers, mountains, valleys and landscapes in Europe would have their origin in Pre-Indo-European languages, specifically the Basque language.

Vennemann:

We do not fall in exaggeration if we say that all the Europeans are Basques.

According to Vennemann, the Proto-Basque language (or a language family from which the Basque language originated) was the linguistic stratum in which the Indo-European languages later settled. He found, among other examples, the Basque words "ibai" (river) and "ibar" (bottom) to repeat continuously in European rivers, or the word "haran" (valley) in toponyms such as Val d'Aran, Arendal, Arundel, Arnach, Arnsberg, Aresburg, Ahrensburg, Aranbach or Arnstein.

The Vennemann theory has been criticized by Basque scholars and it is not accepted by most linguists.[32]

Specifically, Trask, after many pointed critiques of the methods employed, affirmed that Vennemann had found an agglutinative language, but with no relation to the Basque language, and that probably it is simply the Indo-European language, as many other linguistic scholars agree.[33]

Joseba Andoni Lakarra, a researcher of the Proto-Basque language, criticizes the thesis of Vennemann, saying, like Trask, that he identifies modern Basque roots that are not related to the archaic Basque. In the same way, Lakarra says that, despite Basque now being an agglutinative language, there are reasons to believe that previously it was not so.[33]
