2013/03/07: A warning about the accuracy of the tests was made by the Sense About Science campaign group, which said "such histories are either so general as to be personally meaningless or they are just speculation from thin evidence."
The warning was backed by a number of leading genetics experts. Steve Jones, Emeritus Professor of Human Genetics at UCL said: “On a long trudge through history – two parents, four great-grandparents, and so on – very soon everyone runs out of ancestors and has to share them.
"As a result, almost every Briton is a descendant of Viking hordes, Roman legions, African migrants, Indian Brahmins, or anyone else they fancy.”
His colleague Prof Mark Thomas said: "These claims are usually planted by the companies that provide these so-called tests and are not backed up by published scientific research. This is business, and the business is genetic astrology.”
