have been comparing only one or two word pairs at a time. This significantly increases the chance of chance resemblances; you will only gain wide acceptance if you give us systematic correspondences. Or, putting it another way: the null hypothesis here is that any two words which look similar are, in fact, chance resemblances. It’s your job to give us enough data that we feel comfortable accepting that the resemblances are not due to chance.
Actually, this is rather on the contrary: chance resemblances are more likely in large sets of data.
…OK, let’s take this from the beginning.
Consider two languages. These languages will have a certain number of
false cognates, and a certain number of
true cognates. Now, historical linguistics works on the principle that true cognates will have
systematic phonological correspondences, which false cognates will not share. Thus, if you have enough data, the two can be distinguished by checking for systematic correspondences over a large set of words. These will be shared between true cognates, but not false ones.
Thinking about this, it is clear that false cognates are more common in large sets of data. However,
this does not imply that true cognates are more common in small sets of data! (A proposition does not imply its converse; to say so is fallacious.) Rather,
both false and true cognates become more likely in large sets of data, but only large datasets can give the number of systematic correspondences required to meet the standards of (non-crackpotted) historical linguistics.

OK. My view is that proto-languages and genealogical trees for modelling language relationships are a simplification, because they don't take into account (or do it poorly) lateral relationships (substrates and adstrates). In the case of the reconstructed PIE, one can find internal correspondences between the +2000 lexical items which would indicate they come from at least 2-3 different sources (Occam's Razor is at work here).
ah, okay. been a while since I saw a discussion (or even mention?) about the trees vs their alternatives.
But please refresh my memory, because I can't recall what you or anyone else said was a viable other option to the tree model.
To me, at least, a tree still works with lots of loans from other languages.....just look at a Family Tree - there's at least one name (word) from another tree grafting itself in, at least once a generation. Still a tree.
Part of the reason I've never found any of the proposed "alternatives" to the tree model entirely satisfying is because none of them ever seem like they have the same level of descriptive power of the tree model, especially for larger families. Like sure, a wave model works just about when you have a relatively close-knit group of varieties whose speakers see each other as fundamentally unified and where innovations can relatively freely spread across the varieties, as in Early IE, but it's pretty much useless for talking about modern IE as it currently stands, as the major branches are too differentiated from each other for such free spread and contact-induced changes easily show up as a discontinuity in reflexes, e.g. since Proto-Celtic and Primitive Irish lacked *p, as evidenced by the long list of otherwise regular reflexes , any /p/ found in the modern language is a tell-tale sign that it's a loan which came into the language from "outside" and was for a period external to the phonological system, i.e. it was imported across a distinct language barrier. You can talk about "what about substrates and adstrates?" all you like, but the same principle applies - there are a few parts of the language which arrived into the language at a particular point in time but these bits came to an already fully-formed linguistic system which the rest of the language reflects.
The wave model reduces to the tree model in such cases: if your innovations do not overlap, then the various groups become mutually disjoint, same as with the tree model. The wave model however can account for cases such as linkages and creoles, which the cannot be modelled by the tree model.

and then, today, in
New Scientist magazine, someone was making the argument that a lot of words - his examples were mostly in genetics and biology - are outdated and in need of replacement, such as the word
Caucasian(sp) {because it has, over the course of time, varied as to its meaning in regard to geopolitics and beauty}.....and then he said that, because the Bantu family has 400 dialects over a vast swath of land, it is meaningless and useless to say
Bantu.
yeah...."Wha??"
{sorry...felt like sharing}
Oh, dear. Which one was that? Because I have a bunch of unread New Scientists from when I was studying for my exams, and I’d rather know which one to avoid if possible…
