Bryan Sykes the worlds first genetic archaeologist takes us on a journey around the family tree of Britain & Ireland to reveal how our tribal history still colours the country today. In 54BC Julius Caesar launched the first Roman invasion of Britain. His was the first detailed account of the Celtic tribes that inhabited the Isles. But where had they come from & how long had they been there? When the Romans eventually left five hundred years later they were succeeded by invasions of Anglo-Saxons Vikings & Normans. Did these successive invasions obliterate the genetic legacy of the Celts or have very little effect? After two decades tracing the genetic origins of peoples from all over the world Bryan Sykes has now turned the spotlight on his own back yard. In a major research programme the first of its kind he set out to test the DNA of over 10 000 volunteers from across Britain & Ireland with the specific aim of answering this very question: what is our modern genetic make-up & what does it tell us of our tribal past? Are the modern people of the Isles a delicious genetic cocktail? Or did the invaders keep mostly to themselves forming separate genetic layers within the Isles? As his findings came in Bryan Sykes discovered that the genetic evidence revealed often very different stories to the conventional accounts coming from history & archaeology. Blood of the Isles" reveals the nature of our genetic make-up as never before & what this says about our attitudes to ourselves each other & to our past. It is a gripping story that will fascinate & surprise with its conclusions."
