Borean (also Boreal or Boralean)[1] is a hypothetical (i.e. proposed) linguistic macrofamily that encompasses almost all language families worldwide except those native to sub-Saharan Africa, Australia, New Guinea and the Andaman Islands. It is considered a fringe theory within mainstream linguistics, relying heavily on the discredited mass comparison method to derive genetic relationships.[2][3][4] Borean proposes that the various languages spoken in Eurasia and adjacent regions have a genealogical relationship, and ultimately descend from languages spoken during the Upper Paleolithic in the millennia following the Last Glacial Maximum. The name Borean is based on the Greek βορέας, and means "northern". This reflects the fact that the group is held to include most language families that are native to the Northern Hemisphere. Two distinct models of Borean exist: that of Harold C. Fleming and that of Sergei Starostin.
The concept is due to Harold C. Fleming (1987), who proposed such a "mega-super-phylum" for the languages of Eurasia, termed Borean or Boreal in Fleming (1991) and later publications. In Fleming's model, Borean includes ten different groups: Afrasian (his term for Afroasiatic), Kartvelian, Dravidian, a group comprising Sumerian, Elamitic, and some other extinct languages of the ancient Near East, Eurasiatic (a proposal of Joseph Greenberg that includes Indo-European, Uralic, Altaic, and several other language families), Macro-Caucasian (a proposal of John Bengtson that includes Basque and Burushaski), Yeniseian, Sino-Tibetan, Na-Dene, and Amerind.[5]
In 2002, Fleming argued that there were not a two large super-phyla distinction between a Nostratic and a Dené–Caucasian taxon among Borean languages, and that the language kinship between its branches is possibly more complex than a Nostratic versus a Dené–Caucasian super-phyla.[5]
However, in 2013, Fleming had changed his view about this issue in a joint article with Stephen L. Zegura, James B. Harrod, John D. Bengtson and Shomarka O.Y. Keita – "The Early Dispersions of Homo Sapiens sapiens and proto-Human from Africa." in Mother Tongue, issue XVIII, p. 143–188, 2013, where he argues that Nostratic and Dene-Caucasian as language phyla within Borean is a hypothesis that is well grounded and convincing.
Fleming writes that his work on Borean is inspired by Joseph Greenberg's exploration of Eurasiatic, and is oriented towards the concept of "valid taxon". He rejects Nostratic, a proposed macrofamily somewhat broader than Eurasiatic, and withholds judgment on Dené–Caucasian, a proposal that would encompass Sino-Tibetan, Yeniseian, Basque, and several other language families and isolates. Fleming calls Borean a "phyletic chain" rather than a super-phylum. He notes that his model of Borean is similar to Morris Swadesh's Vasco-Dene proposal, although he also sees similarities between Vasco-Dene and Dené–Caucasian. He sees Borean as closely associated with the appearance of the Upper Paleolithic in the Levant, Europe, and western Eurasia from 50 thousand to 45 thousand years ago, and observes that it is primarily associated with human populations of Caucasoid and Northern Mongoloid physical appearance, the exceptions being southern India, southern China, southwestern Ethiopia, northern Nigeria, and the Chad Republic.[5]
The phylogenetic composition of Borean (noncommital about higher linkages within the whole) according to Fleming, Bengtson, Zegura, Harrod, and Keita (2013)[6] is as follows:
According to Sergei Starostin, (2002), Borean is divided into two groups, Nostratic (sensu lato, consisting of Eurasiatic and Afroasiatic) and Dene–Daic, the latter consisting of the Dené–Caucasian and Austric macrofamilies.[11] Starostin tentatively dates the Borean proto-language to the Upper Paleolithic, approximately 16 thousand years ago. Starostin's model of Borean would thus include most languages of Eurasia, as well as the Afroasiatic languages of North Africa and the Horn of Africa, and the Eskimo–Aleut and the Na-Dene languages of the New World.
Murray Gell-Mann, Ilia Peiros, and Georgiy Starostin maintain that the comparative method has provided strong evidence for some linguistic superfamilies (Dené-Caucasian and Eurasiatic), but not so far for others (Afroasiatic and Austric). Their view is that since some of these families have not yet been reconstructed and others still require improvement, it is impossible to apply the strict comparative method to even older and larger groups. However, they consider this only a technical rather than a theoretical problem, and reject the idea that linguistic relationships further back in time than 10,000 years before the present cannot be reconstructed, since the "main objects of research in this case are not modern languages, but reconstructed proto-languages which turn out to be more similar to one another than their modern day descendants".[1] They believe that good reconstructions of superfamilies such as Eurasiatic will eventually help in investigating still deeper linguistic relationships. While such 'ultra-deep' relationships can currently be discussed only on a speculative level, they maintain that the numerous morphemic similarities between language families of Eurasia, many of which Sergei Starostin compiled into a special database that he later supplemented by his own findings, are unlikely to be due to chance, making it possible to formulate a Borean super-superfamily hypothesis.[12]
They have also suggested possible links between 'Borean' and other families. In their view comparisons with 'Borean' data suggest that Khoisan cannot be included within it but that more distant connections on an even deeper level might be possible, that how the African superfamilies Niger–Congo, East Sudanic, Central Sudanic and Kordofanian are related to Borean remains to be investigated, that the situation with the native languages of the Americas remains unresolved, and that while there are some lexical similarities between Borean and the Trans–New Guinea languages, these remain too scarce to establish a firm connection. They comment that while preliminary data indicates possible connections between Borean and some superfamilies from Africa, the Americas, and the Indo-Pacific region further research is needed to determine whether these additional superfamilies are related to Borean or unidentified branches of it.[12] Gell-Mann et al. note that their proposed model of Borean differs significantly from that of Fleming.[12]
Sergei Starostin died prematurely in 2005 and his hypothesis remains in a preliminary form, with much of the material he collected available online.[13][14]
The phylogenetic composition of Borean according to Starostin is as follows:
A computational phylogenetic analysis by Jäger (2015) did not support the Borean macrophylum in its entirety, but provided the following phylogeny of language families in Eurasia:[15]
Allan Bomhard argues that Sumerian did not descend from a daughter language of Proto-Nostratic but from a sister language of it. In other words, Sumerian descended from an older common ancestor language with Proto-Nostratic and did not descend directly from it; that is, Sumerian was closer to Nostratic but not a member of it.[16]
Bomhard argues that Kartvelian is closer to Eurasiatic than to other language families within Nostratic and that the differences are due to the fact that Kartvelian became separated from Eurasiatic at a very early date.[16]
Linguist Asya Pereltsvaig states in Languages of the World: An Introduction that both versions of the Borean hypothesis are "controversial and tentative".[17]
Postulated remote relationships such as Amerind, Nostratic and Proto-World have been featured in newspapers, magazines and television documentaries, and yet these same proposals have been rejected by most mainstream historical linguistics
