@Walter Hinteler,
YOU're the one claiming that you and you family cannot see IE relationships, and the world generally offers no shortage of dopey people in high places...
Nonetheless the claim I was making is basically that the theory of evolution doesn't really work any better for human languages than it does for animals. Sure, you have MICRO-evolution of languages which explain the differences between Russian and Ukranian or between our English and Chaucer's; the claim I also make is that MICRO-evolution (of languages) also accounts for the Germanic/Slavic divide, and that there is no evidence of such MICRO-evolution or any other kind of evolution betweewn IndoEuropean and Semitic or between IndoEuropean and Altaic groups, and that the only relationship there is between language families is borrowed words.
A few examples of things which a bright person would notice between Germanic and Slavic languages:
Numbers: nearly all the same, one, two, three, four... einz, zwei, drei, fier...
один два три четыре (same as quattro/quarter etc.)
Family members: nearly the same... брат, сустра, мати(old spelling), отец... The 'ot' in that last one is the same 'at' in Vater/Pater, the etz is a generic suffix.
Personal pronouns: nearly the same
Common things: fire/огонь (ignire/ignition/Agni), water/вода, wine/вино,
wind/ветер(vent, ventilator etc.)
P/F words (start with a p in one IE language and with an f in the next): flame/пламя, fall/пал (упасть, попасть, пропасть, etc.) , no shortage...
D/G words: give/давать gimme/дай-мне/dai-me (slavic kid language)
Common household things: knife/нож spoon/ladle/Loeffel/ложка
Old/very-old IE roots: it (step)/идти/iterate/itinerary
Feudal relationships: долг/должен(debt, obligation) = do + L-G (as in liege lord), delegate, relegate, obligate etc.
.....
I mean, I'm not even talking about all of the words ending in ия which are borrowed from French, just the words which an alert reader will notice because the roots go all the way back. Again none of those similarities are there between any IE language and Turkish or Mongolian.
