The similarity of cultural elements which exists between the American Indians and Oceania, as well as the pre-Columbian civilisations of America and those of Egypt and the Near and Middle East, have repeatedly been explained by the assumption of cultural contacts between the Old and the New World in pre-Columbian and pre-Magellan times. This was done especially by ethnologists and anthropologists, but also by prehistorians and geographers, despite the established fact that the New World was settled by man via north-east Asia as late as the late Pleistocene period. Same diffusionists assume trans-Atlantic, but most of them trans-Pacific transfer of cultural elements in both directions. If noteworthy contacts did exist, they would have been bound 3.

By studying the oldest possible herbaria, manuscripts, reports about the flora and general reports of travels, the botanist, E. D. Merri!!, came however to the conclusion that, out of about 1500 cultigens of the world which existed at the time prior to Columbus and Magellan, only three species were common to both hemispheres, namely the sweet potato, the coconut, and the common gourd, and that the distribution of the cultigens (with the exception of the three mentioned above) which today are common to both the Old and the New World, is the result of shipping communications during the last 450 years. Thus the botanical data point against notable cultural contacts between the two hemispheres prior to this time. Consequently one has to conclude that the prehistoric civilisations of America must on the whole have developed independently.
