I took the time to read this and it is larded with the usual insults against those who develop points of view that are contrary to the conventional wisdom.
The article starts out with something that has been utterly disproved; the migration across the Bering Strait land bridge. Among other reasons, the natives of the Americas were 100 per cent “O” blood type and no trace of A/B which should have come over from Asia.
Perhaps the Egyptians traded with parties that did cross the Atlantic to the Americas. The people of the Canary Islands coincidentally also mummified their dead like the Egyptians so they’re a possible candidate. It would be interesting if possible to test their mummies of the same time period to see if nicotine and cocaine are also detected. Perhaps they discovered the efficacy of nicotine in preserving mummies and passed that on to the Egyptians.
