My general rule for this type of thing is if it's in a national newspaper ignore it and read the text itself.
Genetic studies on the British Isles (Britain especially, when compared to other nations) are extremely patchy and rarely give consistent data. An academic paper does not mean Something Happened This Way, it just says these are the results and how we've interpreted them. A more reliable picture can only be drawn from a mass of reliable results.
>>3075 I doubt that's your general rule (or national newspapers don't quote genetic studies very often), because I've never heard a research paper referred to as a text before.
