This is an excellent treatment of the origins of the Indo-Europeans and together with Cavalli-Sforza's "Genes,Peoples and Languages" provides where from and at what time period the ancesters of the Europeans originated. Renfrew's only inaccuracy is in infering that at the time of the arrival of the first agriculturalists to the Balkans a Greek association be made. Cavalli-Sforza puts forward a more factual and convincing identifcaton of the language of Albania being the oldest in Europe. These two books present when examined together the most convincing arguments on the topic in particular since they base there presentations on either radio-carbon dating in the case of agriculture or on genes in the case of dating who are the oldest people of Europe.
