However, few other linguists accept Dixon's thesis. For example, Kenneth L. Hale describes Dixon's skepticism as an erroneous phylogenetic assessment which is "such an insult to the eminently successful practitioners of Comparative Method Linguistics in Australia, that it positively demands a decisive riposte". Hale provides pronominal and grammatical evidence (with suppletion) as well as more than fifty basic-vocabulary cognates (showing regular sound correspondences) between the proto-Northern-and-Middle Pamic (pNMP) family of the Cape York Peninsula on the Australian northeast coast and proto-Ngayarta of the Australian west coast, some apart, to support the Pama–Nyungan grouping, whose age he compares to that of Proto-Indo-European.
