"One thing that's become abundantly clear from the ancient DNA revolution of the last 10 years is how important migration has been in the history of our species. So, of course, there has been hybridisation, cultural, genetic, linguistic. There is no such thing as a pure people, pure culture, pure language.

This book was a huge amount of work because the only way you can tell the story of Proto Indo European [the ancestor of Latin and Sanskrit and their daughter languages including English, German, Hindi, Bengali, Punjabi and many, many others] is by combing the fields of linguistics, archeology and genetics.
