Amazing, isn't it, that PreColumbian humans entered the Americas, just once, via an overland route that afterward ceased to exist, in a group numbering no more than 70, and in a hundred years or so covered both continents from the Arctic Circle to Tierra del Fuego, with a population of millions; and yet it took 900,000 years to reach Italy from the Caucasus? ;')
Seeing that my specialty is stupid questions, let me pickle off another one:

Does that seem likely to everybody else?
