A DNA database is using the "markers" that are part of our genetic make-up to reveal the patterns of our heritage, where everybody in this country came from.

Writer and historian Alistair Moffat, who is running the project in the Scottish Borders, says that they have been discovering that the Bible is "beginning to come alive".

He told the Today programme that it is about "deep ancestry... where we all came from".

Mr Moffat also discussed the idea of the UK's genetic heritage.

"Everyone in Britain is an immigrant, of course, the only issue is when did you arrive?" he told Jim Naughtie.
