Leif Erikson
Research done in the early 1960s by Norwegian explorer Helge Ingstad and his wife, archaeologist Anne Stine Ingstad, identified a Norse site located at the northern tip of Newfoundland. It has been suggested that this site, known as L'Anse aux Meadows, is "Leifsbúðir". The Ingstads demonstrated that Norsemen had reached America about 500 years before Christopher Columbus. Later archaeological evidence suggests that "Vinland" may have been the areas around the Gulf of St. Lawrence and that the L'Anse aux Meadows site was a ship repair station and waypoint for voyages there. That does not necessarily contradict the identification of L'Anse aux Meadows with "Leifsbúðir" since the two sagas appear to describe "Vinland" as a wider region which included several settlements. The "Saga of Erik the Red" mentions two other settlements in "Vinland": a settlement called "Straumfjǫrðr", which lay beyond "Kjalarnes" promontory and the Wonderstrands, and one called "Hóp", which was located even farther south.
Leif was described as a wise, considerate, and strong man of striking appearance. During his stay in the Hebrides, he fell in love with a noblewoman, Thorgunna, who gave birth to their son Thorgils. Thorgils was later sent to Leif in Greenland, but he did not become popular.
Jeffrey Goodman
Goodman claims that the fossils in North America are "twice as old as the oldest fully modern skull from europe". In his work he attempted to show that the American Indians were not only the first Americans but were the first humans on earth. Goodman allows that hominids did appear in Asia and Africa, though homo sapiens are completely American in origin according to his theory. Goodman's theory has been criticised as his explanation of the relationship between hominids and humans was vaguely discussed. However Goodman in a later book addressed the issue in "The Genesis Mystery: the Sudden Appearance of Man" (1983) in which he criticised natural selection and advocated a type of spiritual evolution by claiming that archaeological findings verify an unbridgeable gap between modern man and the last "pre-man" creature and advocates spiritual intervention as the explanation for the "sudden appearance" of modern man. According to Michael Anthony Corey: Goodman "appeals to an intervening supernatural force, which would have manifested itself entirely through a "natural" series of evolutionary processes".
