European Cavemen in America?

New evidence suggests Stone Age hunters from Europe discovered America
New archaeological evidence suggests that America was first discovered by Stone Age people from Europe – 10,000 years before the Siberian-originating ancestors of the American Indians set foot in the New World. A remarkable series of several dozen European-style stone tools, dating back between 19,000 and 26,000 years, have been discovered at six locations along the US east coast. Three of the sites are on the Delmarva Peninsular in Maryland, discovered by archaeologist Dr Darrin Lowery of the University of Delaware. One is in Pennsylvania and another in Virginia. A sixth was discovered by scallop-dredging fishermen on the seabed 60 miles from the Virginian coast on what, in prehistoric times, would have been dry land.


It's one of the things I need to constantly remind myself of.  With 100 m of sea level rise since the low sea level stand of the last glaciation, much of the area where human settlement would have concentrated, along the coasts, has been drowned and covered with sediment by the rising sea.
Solutrean tools from France, Portugal
The similarity between other later east coast US and European Stone Age stone tool technologies has been noted before. But all the US European-style tools, unearthed before the discovery or dating of the recently found or dated US east coast sites, were from around 15,000 years ago - long after Stone Age Europeans (the Solutrean cultures of France and Iberia) had ceased making such artefacts. Most archaeologists had therefore rejected any possibility of a connection. But the newly-discovered and recently-dated early Maryland and other US east coast Stone Age tools are from between 26,000 and 19,000 years ago - and are therefore contemporary with the virtually identical western European material.

What’s more, chemical analysis carried out last year on a European-style stone knife found in Virginia back in 1971 revealed that it was made of French-originating flint.
Looks Solutrean to me...

OK, now that's cool, forensic evidence that stone tools found in the Americas originated in the old world.  Unless a bird carried it, it's unlikely to get there via any mechanism except people.
Professor Dennis Stanford, of the Smithsonian Institution in Washington DC, and Professor Bruce Bradley of the University of Exeter, the two leading archaeologists who have analysed all the evidence, are proposing that Stone Age people from Western Europe migrated to North America at the height of the Ice Age by travelling (over the ice surface and/or by boat) along the edge of the frozen northern part of the Atlantic. They are presenting their detailed evidence in a new book - Across Atlantic Ice – published this month.

At the peak of the Ice Age, around three million square miles of the North Atlantic was covered in thick ice for all or part of the year.

However, the seasonally shifting zone where the ice ended and the open ocean began would have been extremely rich in food resources – migrating seals, sea birds, fish and the now-extinct northern hemisphere penguin-like species, the great auk.
The Inuit (Eskimos in pre-PC days) had an Arctic encircling culture in recent history, and they were certainly at a stone age level of culture, so it it entirely plausible that a similar, earlier culture could have crossed the icy North Atlantic and planted the seeds a culture there.
Stanford and Bradley have long argued that Stone Age humans were quite capable of making the 1500 mile journey across the Atlantic ice - but till now there was comparatively little evidence to support their thinking.

But the new Maryland, Virginia and other US east coast material, and the chemical tests on the Virginian flint knife, have begun to transform the situation. Now archaeologists are starting to investigate half a dozen new sites in Tennessee, Maryland and even Texas – and these locations are expected to produce more evidence.
Not mentioned in this article is the hypothesis that the Solutrean technology formed the basis of Clovis culture, the first North American wide stone tool culture that for years was thought to represent the first human settlers in the Americas and the ancestors of virtually all Native American (formerly American Indians)
Another key argument for Stanford and Bradley’s proposal is the complete absence of any human activity in north-east Siberia and Alaska prior to around 15,500 years ago. If the Maryland and other east coast people of 26,000 to 19,000 years ago had come from Asia, not Europe, early material, dating from before 19,000 years ago, should have turned up in those two northern areas, but none have been found.

Although Solutrean Europeans may well have been the first Americans, they had a major disadvantage compared to the Asian-originating Indians who entered the New World via the Bering Straits or along the Aleutian Islands chain after 15,500 years ago.

Whereas the Solutreans had only had a 4500 year long ‘Ice Age’ window to carry out their migratory activity, the Asian-originating Indians had some 15,000 years to do it. What’s more, the latter two-thirds of that 15 millennia long period was climatologically much more favourable and substantially larger numbers of Asians were therefore able to migrate.

As a result of these factors the Solutrean (European originating) Native Americans were either partly absorbed by the newcomers or were substantially obliterated by them either physically or through competition for resources.

Some genetic markers for Stone Age western Europeans simply don’t exist in north- east Asia – but they do in tiny quantities among some north American Indian groups. Scientific tests on ancient DNA extracted from 8000 year old skeletons from Florida have revealed a high level of a key probable European-originating genetic marker. There are also a tiny number of isolated Native American groups whose languages appear not to be related in any way to Asian-originating American Indian peoples.
I hadn't heard about the genetic marker evidence before.  I would think that this idea is getting more solid all the time.  At least as solid as all the stories that are being created about the modern human/Neandertal/Denisovan interbreeding, which currently get talk about as if they're very nearly settled science.

  1. Atlantis populated both eastern America and Western Europe during the ice age

  2. I don't think we yet appreciate how far our early ancestors roamed. I could easily imagine them following some herd of game across the North Atlantic ice and down into America. We need some of their DNA.

    And by the way, your Solutrean women are just charming, if a bit idealized.

  3. I assume it doesn't work in people as it does for dogs.
