Review of Pagel et al. 2013: "Ultraconserved words point to deep language ancestry across Eurasia" Jaakko Häkkinen, 14th May 2013 The aim of the authors is to reach beyond the conven- *kêri 'bark'. Such cognates are not seen in the tional language families, all the way to the Ice Age Swadesh lists, because in the modern languages a superfamily from which many of the present Eurasian more common word is used instead of the old language families would have evolved.

Etymological neous taxonomic illustration (family tree) of the cognates give a very different picture from that of language family: some other language with less "normal" Swadesh list cognates based on mean- semantic shifts or rarefications caused by newer ings. A few observations between Finnish and words might seem to be closer than a language Hungarian: with more semantic shifts or rarefications. – For the meaning 'snake' the words are not cognates: Hungarian has kígyó, Finnish has käärme. The Finnish word is a Baltic loan- word (cf. Lithuanian kirmis 'snake'), but Finnish also has a cognate for the Hungarian word: kyy 'adder' < *küji(wa) 'snake' > kígyó 'snake'. The Finnish word has gone through a specializing semantic shift. – For the meaning 'bird' the words are not cog- nates: Hungarian has madár, Finnish has lintu. But Hungarian also has a cognate for the Finnish word: lúd 'goose' < *lônta 'bird' > lintu 'bird'. The Hungarian word has gone through a specializing semantic shift. Temporally the situation means, that the common There are also other words in the Swadesh lists, protolanguage behind Hungarian and Finnish is which have cognates both in Hungarian and Finn- erroneously assessed much older than it actually ish but which have undergone a semantic shift or is. The meaning-based Swadeshian lexicostatistics become rarefied by newer words in one of the simply ignores many cognates existing in the languages: for example Proto-Uralic *mälki modern languages, even though all the cognates 'breast', *näki- 'to see', *kuji 'fat', *piŋi 'tooth', should definitely be taken into account when as- 1 sessing the age of the split between the related The authors of the article do not follow this order languages.
