There are indications that a cultural influx occurred in America coming from Europe in Solutrean times (20-17,000 years BC).There is also genetic evidence that Azores Islands, placed in Middle Atlantic, were already occupied by Oriental people before the Portugese arrival according to HLA genes. In addition, Pacific HLA aleles, including Australia, Islands and southern Asia, are shared with present day Amerindians. Thus, America peopling could have been more complicated than thought, particularly through trans-oceanic routes.
In the present paper, we show evidences that relate Megalithic Atlantic culture (6,000 years BC) with southern America cultures based on stone functional construction structures. Moreover, both Atlantic and Pacific HLA markers seem to be shared with Anerindians and Azores Oriental genes.
Results are discussed in the frame of genetic and archeological similarities of First American Inhabitants, with Atlantic and Pacific inhabitants, particularly in Megalithic European times (6,000 years ago). This is the first time that these striking similarities are descrbed. Taken all these data together, it may be hypothesized that frequent Oceanic routes were used to reach America at different times before Columbus arrival et 1492 AD.
