However, the question of external relationships of Kalaw Lagaw Ya is also complicated by resemblances between both the Paman (Pama-Nyungan, Australian languages) and the Trans-Fly (Papuan) languages. Though few, these may be significant, and include forms such as those noted below, not all of which appear in Kalaw Lagaw Ya. Such resemblances could point to a deep-level relationship dating back to before the flooding of Torres Strait at the end of the last age, as claimed by Mitchell , or they could point to genetic inheritance and subsequent language contact, as discussed by Alpher, Bowern, and O'Grady 2009.
