The debate on whether Vikings were in Pre-Columbus America is starting to sound a lot like the back and forth of "$food is (good|bad) for you".

I do not think this has been in serious dispute in the last 50 years. This paper just puts a more precise date on the settlement in Newfoundland that was already well known.

Parallel evolution of two strains of smallpox might have meant still no immunity to the Spanish version several centuries later. And the diseases were only a small factor in the outcome of the colonization. Guns being a much larger factor, for example.

It would also mean smallpox would spread the other way. It’s interesting that the transfer of disease was so heavily one-sided.

It’s not surprising at all. If you assume naively that development rate of a novel disease is proportional to population, then the World, which had a 6:1 greater population would have 6 times as many communicable diseases. Similar argument if you base it off of land mass, number of wild animals, number of domesticated animals, etc.

(Actually, I do think the New World peoples were particularly prolific when it came to domesticating plants… they punched way above their population size in terms of number of today’s staple foods they domesticated… plus chocolate, vanilla, etc…)

An interesting counter-factual that comes to mind - if the Norse Greenlanders had brought smallpox or other diseases with them, then Native Americans would have had 500 years to recover (and keep immunity?) - The conquistadors would have faced millions of not-dying-natives. A much different world would have resulted.

The book "1491" describes the Americas before Columbus, and is very interesting. In particular, the population density was much higher than generally realized.

Especially in Aztec cities

Is that true? I've read that 90+% of the population died from diseases, the vast majority without ever knowing about the European conquerors (that is, they never saw a gun). Imagine if 90% of the people in your nearest city died. How difficult would it be for a new group, immune to whatever killed almost everyone in the city, to move in and take over?

I've always wondered why this wasn't a two-way street. Wouldn't native people also have diseases to share? I know the imperialists weaponized their diseases and intentionally tried to spread it and that may be the difference. Usually the smallpox theory is presented in a way that removes agency and culpability from the conquerers. It's always struck me as remarkably convenient and quite unbelievable; they were an idy…

Population density and totals, and their proximity to animals and their waste, matter. Extensive trade and empire building exposes people to new pathogens and allows new ones to develop, as well.

This is not accurate. Individual epidemics did not have mortalities even approaching the 90% range. What actually happened were dozens of epidemics over decades or centuries. Moreover, outside the Northeast, Columbian epidemics are closely associated with persistent European contact and colonization. It should also be noted that human populations are incredibly resilient to epidemics. In the absence of "other things"…

Isn't that because Europe was able to bounce back while in the Americas, the diseases were immediately followed up by the European colonizers who didn't give them time or space to repopulate?

That's exactly the point. Epidemic disease alone is an insufficient explanation for the demographic collapse of indigenous Americans.

There are plenty of valid claims that many other civilizations contacted America: https://en.wikipedia.org/wiki/Pre-Columbian_trans-oceanic_co... But it is meaningless since they did not write about it nor they stablished commerce. The fact is that before 1492, most civilizations in Africa/Asia/Europe did not know that America existed and that other humans lived there. After 1492, that changed forever.

Depends on what you find meaningful! There was almost certainly exchange of goods between Polynesians and South Americans. The presence of early sweet potato agriculture in Polynesia and genetic admixture in both regions points to non-trivial contact. There are even parallels in terms of folk-tales [0]! (Though these are likely older events, more to do with ancient dispersal).

There are also possibly earlier relationships across the Pacific, but these would have been ancient and interesting largely from historical curiousity [1].

The Icelandic sagas suggest that the Norse engaged in cultural exchanges with the Indigenous groups of North America34. If these encounters indeed occurred, they may have had inadvertent outcomes, such as pathogen transmission7, the introduction of foreign flora and fauna species, or even the exchange of human genetic information. Recent data from the Norse Greenlandic population, however, show no evidence of the las…

I think the consensus has been for some time that they showed up, caught some fish, logged a few trees, decided it sucked, and left, all in probably less than a decade.

Sounds like my summer vacation in Newfoundland in July 2021.

Not much has changed! Kidding.

Unless they were fishing for cod (usually offshore), they weren't doing so well on the Northern Peninsula of Newfoundland. And the trees in that area of Newfoundland are skinny, short, and useless for most construction.

I think they just landed on the part of Newfoundland that has the least to offer. It's still that way 1000 years later.

Had they landed in one of the bays on the East Coast of Newfoundland, they might have enjoyed better weather, better shelter, better fishing, and more contact with the local aboriginal population.

The first African to climb Mt. Everest, you say? Well he didn’t help build a network of base camps so I’m just going to say that it’s meaningless.

This is the part I don't get. These guys were awesome sailors. It didn't occur to them to sail down the coast until they got to the Florida Keys and set up a little surf shop?

The major sea currents run towards north here

And they had no base nearby to launch from. Go back home and stock up? Noo.. home was Greenland, there's no riches there, and they went to Vinland to try to stock up.
