"Another reason for not relying too much on the theories of the linguists is that Austronesian linguistics is a very demanding field, comprising the study of hundreds of small languages most of which have no literature, so the number of genuine experts is far smaller than in the case of IE, and even in the latter case linguists are nowhere near a consensus on the homeland question. Linguistic evidence is very soft evidence, and usually the data admit of more than one historical reconstruction, so I don't think there is any compelling evidence against a Sundaland homeland hypothesis. Conversely, archaeological and genetic evidence in favour of the spread of the Austronesian-speaking populations from Sundaland seems to be sufficient."
