Query: An unconvincing defence of an outdated model

A great deal of recent archaeological evidence has muddied up the picture of the evolution of the Indo-European languages created at the end of the 19th century. This picture was inspired less by good scholarship and more by Eurocentrism and racism. Mallory rehashes old, tired arguments. A lot of the linguistic arguments are based on old, incomplete surveys. For example, on page 114 Mallory mentions that *mori (for sea) is found only in European languages. But it is a common word for a large body of water in Kashmiri. Even Kannada has a cognate.The book is replete with such errors. The PIE proponents must consider the possibility that the evolution of languages is likely to have been a very complex affair and their simplistic model is at variance with the facts.
