The Welsh are more similar to the earliest settlers of Britain after the last ice age than any other people in the UK, according to a new study into the genetic makeup of the British Isles.
An international research team used DNA samples collected from more than 2,000 people to create the first fine-scale genetic map of any country in the world.
By comparing this information with DNA samples from over 6,000 Europeans, the team was also able to identify clear traces of the population movements into the UK over the past 10,000 years.
- There was not a single “Celtic” genetic group. In fact the Celtic parts of the UK (Scotland, Northern Ireland, Wales and Cornwall) are among the most different from each other genetically.
- The Welsh appear more similar to the earliest settlers of Britain after the last ice age than do other people in the UK.
- There is genetic evidence of the effect of the Landsker line – the boundary between English-speaking people in south-west Pembrokeshire (sometimes known as “Little England beyond Wales”) and the Welsh speakers in the rest of Wales.
