One thing to keep in mind here is that the Kantek evacuation to Earth was supposed to have happened about 80,000 years ago. If the fall of Atlantis was approximately 12,000 years ago, then the Kantekkian evacuation occurred nearly seven times further back in time than that. That allows time for all sorts of population admixture, movement, relocation after various cataclysms, etc, and it is a small miracle (which is partly why I asked the question I did) that any coherent Kantekkian signal can still be discerned, linguistically or otherwise, over that great of a time-depth (the traditional assumption today in the linguistic community is that a linguistic signal is lost after about 6,000 years; clearly not the case in light of the C's answer about Nostratic).
