Greenberg's subgrouping of these languages has not been accepted by the few specialists who have worked on the classification of these languages.[citation needed] However, the work of Stephen Wurm (1982) and Malcolm Ross (2005) has given a small amount of mainstream support for his hypothesis. Wurm stated that the lexical similarities between Great Andamanese, West Papuan and Timor–Alor–Pantar families "are quite striking and amount to virtual formal identity [...] in a number of instances." He believes this to be due to a linguistic substratum.
