Original sentence: Farley Mowat in his book The Farfarers postulates that there was trans-Atlantic explorartion and migration of the Albans who were a Celtic people from the British Isles.He claims there is physical and documentary evidence of these voyages.Once there they inter-married with the native populations and were assimilated.The sole exceptions mainstream archeology has accepted were visits by the Vikings to Newfoundland at the L'Anse aux Meadows site.Under pressure from the Vikings invasions, they migrated to Iceland and Greenland before settling in Ungava and Newfoundland.While the Landbridge Theory of Americas' settlement has dominated archeological thinking for years, like any scientific theory it should be open to refutation by new evidence which is convincing enough
Edited sentence: The sole exceptions mainstream archeology accepted were visits by the Vikings to Newfoundland at the L'Anse aux Meadows site.While the Landbridge Theory of Americas' settlement has dominated archeological thinking for years, it would be unjustified intellectual arrogance to callously disregard other theories and ignore new evidence
