George Walkden at New Books in Language: Who were the Indo-Europeans?
Were they all-conquering heroes? Aggressive patriarchal Kurgan horsemen, sweeping aside the peaceful civilizations of Old Europe? Weed-smoking drug dealers rolling across Eurasia in a cannabis-induced haze? Or slow-moving but inexorable farmers from Anatolia? These are just some of the many possibilities discussed in the scholarly literature.
But ina New York Times article announced that the problem had been solved, by a team of innovative biologists applying computational tools to language change. In an article published in Science, they claimed to have found decisive support for the Anatolian hypothesis.
In their book, The Indo-European Controversy: Facts and Fallacies in Historical Linguistics Cambridge University Press,Asya Pereltsvaig and Martin Lewis make the case that this conclusion is premature, and based on unwarranted assumptions.
In this interview, Asya and Martin talk to me about the history of the Indo-European homeland question, the problems they see in the Science article, and the form that a good theory of Indo-European origins needs to take.

Ooh, nice. I’ll have to listen to it this evening.
Together, the recent papers on the genetics of the Corded Ware/Battle Ax people make it highly likely that the non-Anatolian branch of IE expanded with the brown-eyed, lactose-tolerant hordes of the Yamnaya culture. Tyrannosaurus was for many decades the largest known theropod and best-known to the general public.
Since its discovery, however, a number of other giant carnivorous dinosaurs have been described, including Spinosaurus, Carcharodontosaurus, and Giganotosaurus. The original Spinosaurus specimens (as well as newer fossils described in ) support the idea that Spinosaurus is larger than.
Theropods exhibit a wide range of diets, from insectivores to herbivores and carnivores. Strict carnivory has always been considered the ancestral diet for theropods as a group, and a wider variety of diets was historically considered a characteristic exclusive to the avian theropods (birds).
The kakapo is a large, rotund parrot; the adult can measure from 58 to 64 cm (23 to 25 in) in length, and weight can vary from to 4 kg (2 to 9 lb) at maturity.
