• Isn't that genetic mix likely to be quite similar across the UK, given how small the island is?
    It's about as racist as people from North London teasing those in South London.

  • Surprisingly enough, regional groups that correlate to post-Roman immigration are still extant.

    This is based upon genetic analysis.

    Perhaps more surprising, is that the same results are achieved with the analysis of surnames: eg a Lancashire Wilson will have a common heritage with most other Lancashire Wilsons.

    It's only since the industrial revolution that any more than a small minority have been mobile to any appreciable degree. And, in relative terms, that is very recent.

    And even then, much of the migration preserved the original groups: people largely migrated to their regional centre, rather than to centres in other regions.
