Mentions about the Viking, Roman or Norman invasions of Britain make me wonder if my family or any of my friends originate from those peoples. I’m also intrigued by the way recent work using DNA analysis can build up an overall lineage of modern people which originates in a small group of individuals in Africa around 200,000 years ago. So, I got to thinking that it would be an interesting TV programme to track down the origins of a whole bunch of our very diverse British population using modern DNA analysis. We might all be surprised about how foreign we all are and yet how closely we are all related.
