Original sentence: The people of the islands have a genetic link to the ancient British tribal people who inhabited the islands long before the arrival of the Celts or Romans.The vast majority of the population are either Cornish or English, and the ethnic makeup of the islands is almost exclusively White
Edited sentence: The contemporary population is an eclectic mix of United Kingdom citizens, many from the Home Counties, and more recently temporary Eastern European immigrants.The ethnic makeup of the islands is almost exclusively White.The indigenous Cornish are increasingly under represented in the demographic profile, having been econmically displaced by mainland-incomers.Whilst there is little evidence to substantiate the claim, it is tenuously suggested, that the early inhabitants of the islands may have had a genetic link to the indigenous ancient British who inhabited the islands long before the arrival of the Celts or Romans
