There might be also even older connection human languages present in this word. In the Native American Navajo language a word for brother is "ánaaí" and in the European isolate Basque language it is "anaia". The only connection between those two languages is the Ancient North Eurasian component but also the Neanderthal component (in Western European Hunter-Gatherers) and there is a higher possibility that this word comes from the Neanderthals in this case. This "ana" component is also preserved in the Polynesian words such as Malagasy "anadahy" and Maori "tuakana".
