Borean languages

Borean (also Boreal or Boralean) is a hypothetical linguistic macrofamily that encompasses almost all language families worldwide except those native to sub-Saharan Africa, New Guinea, Australia, and the Andaman Islands. Its supporters propose that the various languages of 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", based on Greek βορέας, means "northern". This reflects the fact that the group is held to include most language families native to the northern hemisphere. Two distinct models of Borean exist: that of Harold C. Fleming and that of Sergei Starostin.
