Modern humans (H.s.sapiens) were present in western Europe by 35 000 B. During the final glaciation they occupied the area south of the major ice sheets, including both Spain and southern Britain.
This Late Palaeolithic population is thought to have been relatively open with regard to mating networks, and mutations could have circulated among the founder populations of Spain and the British Isles.
The people sent there over the centuries came from either the Bay of Biscay or from the western coasts of Ireland which they may have used as a repair and resting staion.
From the Bay of Biscay, they brought any needed tools, livestock and nets.
The rhesus negative blood factor is a recessive phenotype while the O rhesus positive factor is a dominant phenotype.The first and most important of these bases established was likely on Orkney, which has the longest record of continuous settlement of the British Isles and has rich archaeological sites to prove it.The traditional view of the origin of the Picts is that they started out settling the other islands from Orkney as is written by Bede in "The Eclesiastical History of the English People" (731 A.
