All very interesting, but none of it likely to "shed a lot of light on many theories claiming that Negroid and Caucasian people once lived in South America", since such racial theories are more than a little outdated. Such matters would attract more inquiry if they weren't wrapped in crude obsolete language.
Meh, I used crude and obsolete language because the theories are old, and that's the language used in the books I read them in. I know full well it's outdated, but I have no idea of the language used in modern racial theories, (aside from the word;
haplogroup. The meaning of which I forgot a long time ago) so I used those terms.
Verbose, I don't know of any links, but I first read of the Incas' interesting characteristics in a book called
We are not the first by Andrew Tomas. The book is basically a defence of Erich Von Daniken's ideas, although it's far better written, which made me suspicious. I then researched the Incas on my own, and found out the same things that Mirc did. I heard Carthaginian and Roman however, not Viking. All those theories are equally unlikely though.
As for people of Inca blood living in Peru/Ecuador; one thing you have to realise is that Tupac Amaru was basically the last Inca nobleman who was even close to a pure-blooded Inca. Since the Inca felt, as Mirc mentioned, that the Spaniards were related to them - an idea they felt confirmed by the fact that the Spaniards defeated them, something they didn't feel any 'inferior' peoples could possibly have done - they had no problem intermarrying with Spaniards, something they refused to do with other peoples. The Spaniards obviously didn't have a problem intermarrying with Incas, as it both gave them power and, let's face it, the Spanish intermarried with
everyone, regardless of skin colour, something many Europeans would have been aghast at.
Also, the Incas didn't leave corpses. They burned their enemies, and mummified their own people. Like in Egypt, most of these mummies were taken by grave robbers, leaving only four extant mummies in the British museum. Those four were later destroyed when that wing of the museum flooded. So anyone with Inca blood nowadays has only a small portion of genetic material remaining, making any testing extremely difficult.
As for the people wondering about the Greek "pony express." I didn't mean the Greeks had one, I just used Marathon as an example of a human being running a long way to deliver news. I did say that the Inca didn't run themselves to death.
