There has been some intriguing, but obscure,
evidence from the world of genetics, regarding middle eastern/Mediterranean/Agean contact with the new world.
Guthrie's paper also deals with other HLAs, with interesting inferences:
The A*32 allele seems to indicate a Mediterranean or specifically Aegean impact in the Caribbean region (including on the Cherokee) as well as on
Tupians of the lower Amazon (Oyampí and Parakana). It seems to connect this set and the Central Amerind composite with northern India, Sardinia, the
Tuareg of Algeria, and with populations around the Adriatic Sea in Greece, Yugoslavia, and Italy. A*32 is absent from other South American samples
except the Mapuche.
A*32 levels in the Mapuche, Oyampí, and the Central Amerind composite samples are among the top nine in the CS tabulation (7-9%), and the Tupian
Oyampí near the mouth of the Amazon River have the second highest American frequency. If this is not an artifact of sampling [...]
Both A*32 and A*30 are found at significant levels in Greece, Sardinia, and in the Central Amerind composite. They also appear at anomalously high
frequencies in Samoan outliers but are not documented elsewhere in Pacific islands. This may reflect limited exploration of the Pacific by
Mediterraneans who otherwise left few traces except (controversial) petroglyphs. 
And a link to the original paper.
Just a little from this very informative paper,
Table 3 lists all 18 “non-Indian” alleles in decreasing order of their contribution to the American total. The most important is Afro-Asiatic
B*21, which contributes 10.4% of the atypical HLAs found in American samples. Six alleles account for more than half of the total. The nine
Afro-Asiatic types together contribute 47%; the five southern Asian types, 28%; and the four European types, 25%. These percentages are only
approximate as they stand and would doubtless change with more complete sampling or with changes in classification.
Some of this "signal" might arise from the fact that the Portuguese colonized Brazil much earlier than is currently accepted, when the Spanish were
sniffing around in the early 16th century, there were already established sugar plantations, filled with north and west African slaves.
Another paper on the same Cavelli-Svortza data claims the Aegean alleles found are ancestral, and by the time of European colonization, were
extremely rare in populations of the 16th century.
Very provacative info indeed.
