Dolichocephaly is characterised by the skull width reaching less than 76 percent of the skull breadth. It was widespread in many early humans, including Cro-Magnons and Neanderthals. Dolichocephaly is very common in many tropical populations today, especially throughout Africa, India, Australia, and New Guinea. Here it appears in all climate zones from rainforests to deserts, but not all groups are on average dolichocephalic. In Europe a few areas of Spain, South Italy, Scandinavia, and Great Britain have traditionally been dolichocephalic, although European dolichocephaly has recently increased. In America it appears in Inuit as well as some Lagid groups, in East Asia dolichocephaly appears only sporadically, more frequently only in Ainu.
