The fascinating story of how Proto-Indo-European became the ancestor of the languages, including English, Greek and Urdu, spoken by half the people in the world.
- “One view ... is that language ... was invented in the deserts of south-eastern Africa around eighty thousand years ago, perhaps by a group of children ... playing a game.” (Introduction)
- “Hotspots of linguistic diversity coincide with hot spots of biodiversity, because these regions can support a higher density of human groups speaking different languages, who don't need to stray.” (Introduction)
- “On average it takes between five hundred and a thousand years for a language to become incomprehensible to its original speakers.” (Introduction)
- “Indo-European is ... the best documented and in many ways the best understood of all the world's language families, but it also drags the most outdated intellectual baggage behind it. It's like the star patient of a tail-coated nineteenth century doctor, hauled out woozily for public display, underwear slipping off its shoulder, feted and abused in equal measure.” (Introduction)
- “Languages broadly reflect the cultures with which they are associated, because people tend to have more words for the things that matter to them.” (Introduction)
- “Migration ... drives a wedge between dialects and brings them into contact with different languages.” (Introduction)
- “Genes and languages are transmitted differently.” (Introduction)
- “Water rolled over that giant weir with the force of two hundred Niagara Falls, triggering a tsunami that surged through estuaries and lagoons and flooded an area the size of Ireland.” (Ch 1)
- “People who spoke of wheels and wagons could not have lived before 3500 BCE, when that technology was invented.” (Ch 2)
- “Most European men alive today ... carry Y chromosomes that came from the steppe.” (Ch 3)
- “Groups of Indians who speak languages descended from Sanskrit today typically carry more steppe ancestry than those who speak non-Indo-European languages. ... The traditional guardians of the holy texts, the Brahmins have more steppe ancestry than other social groups.” (Ch 6)
- “The percentage of the Globe population defined as international migrants has remained stable since 1960, at about three per cent. Refugees ... on average ... account for ... ten per cent ... of that three per cent.” (Conclusion)
- “Richard the Lionheart ... probably could not speak English. His mother tongue was Occitan.” (Conclusion)
- “Elizabeth the First ... helped English do away with the double negative ... and replace ‘ye’ with ‘you’.” (Conclusion)
- “Migration has been a constant, ‘indigenous’ is relative. ... The most successful language the world ever knew was a hybrid trafficked by migrants. It changed as it went, and when it stopped changing, it died.” (Conclusion)
- “The past is a lighthouse not a port. (Russian proverb)” (Conclusion)
Fascinating and enlightening.
