New study shows Scotland "one of the most diverse nations on earth"

Conventional wisdom states that most of the Scottish population stems from Scots, Celtic, Viking and Irish ancestry, but a new DNA study shows something quite interesting. Many Scots carry genetics originating in West African, Arabian, south-east Asian and Siberia.

Alistair Moffat and James F. Wilson have released a new book, The Scots: A Genetic Journey, which draws on the latest DNA research to document Moffat's statement that Scotland is "one of the most diverse nations on earth." One percent of the population, for instance, is of Berber ancestry, a people who may have moved to Scotland is medieval times from the caliphate of Cordoba in Spain.
