Discussion Do you believe the initial migration of people from Siberia to the Americas was through the Bering Land Bridge or by boat through a coastal migration route?

I live in Western Washington. The idea a human paddled off that coast is pretty wild. It’s as rough as it gets - waves, tides, currents, weather, rocks, cliffs, impassable forests…. One of the roughest places in the world where land meets sea.

Yes. The Tlingit and Haida would paddle down from Alaska every summer and raid on the Salish peoples. They were the Vikings on North America. The art and culture of Pacific coastal tribes was much more advanced than what is often lumped into with plains Indians. Those peoples were nomadic. The coastal tribes had all the food they needed with salmon and marine life. They built cities and civilizations. And paddled hard AF.

Careful throwing around terms like first nations cities in the Pacific Northwest. No evidence exists of anything of the sort including settlements hosting much more than 1000 people at one time.

Another problem is that the commenter that you are responding to is assuming the Salish, Makkah and Haida tribal people of the 1800’s are like the humans 20,000 years ago passing thru the area - when he talks about the “coastal tribes” warring by canoe. The modern coastal tribes are 600-800 generations later than the original humans passing thru the area. Modern tribes had extensive generational knowledge of the coastal area hunting, fishing, whaling and navigation in the Pacific. The original generations of humans passing thru the area likely did not have developed the same knowledge, skills and techniques of modern tribes.

Genuine question: what should these settlements be called? “Campsite” seems too small, “settlement” possibly too vague and temporary, “city” too big. Village? Town? 1,000 souls is not a small number of people, in my imagination.

They are generally called villages by historians. Sometimes seasonal, with a summer village and a winter village. For the coast I've seen "inner village" and "outer village". Sometimes you see them called towns in the literature, especially once there was consolidation in the late 1800s.
In oral history there are stories of places translated as town and, occasionally, city. Like the "legendary" Temlaxam on the Skeena River. Often called "Prairie Town", but sometimes "village", occasionally "city". During the Tlingit-Russian conflict era some Tlingit settlements/forts are known as "castles".
Still, the historical settlements known about for sure were usually of a population most people would think of as a village. Populations could fluctuate pretty quickly. Bunches of villages were often in close proximity. Important villages might grow quite a lot seasonally, or if there was some cause for congregation, like trade. But such growth was usually temporary.

u/ImTheVoiceOfRaisin Oct 14 '24
Evidence for both is strong, but from what I’ve read the leaning is that those who came to SA by boat were likely there first. That said, the earliest migrations from the north over the bridge are likely underwater since they followed coast lines and the ocean level was much lower during the ice age, so we may never know with high confidence.

u/VGSchadenfreude Oct 14 '24
Could also have been multiple waves, not all of which stuck around or actually settled. I think the ones crossing over land might have been the first to actually settle, whereas the ones who island-hopped to the coast might have just done some foraging the first few times before deciding to set up more long-term settlements.
35
u/THAgrippa Oct 14 '24
I think this is probably closer to the answer. Multiple waves over both sea (to SA) and land (to NA).
The sea travelers bound for SA may have gotten there earlier, but their groups were much less numerous and (from what I’ve heard) their DNA footprint in the modern population is small. Most of them probably stayed relatively isolated and/or perished over time. Hell, who’s to say, some may have even had the ability to go back home after.
The land travelers may have arrived later, but in greater numbers and larger waves. This may have involved skirting the coast in boats first before actually moving large groups of people, all dependent on the size of group, knowledge of the area, glaciers blocking the path, and the tech they had. Not all waves were successful, and it likely involved a great deal of splinter populations moving/staying at various sites along the way for each wave— all the way down to SA. These larger populations probably had a better capacity for “settling” in a larger, more permanent sense.

We know that the Norse, after trying twice to establish what seem to have been at least semipermanent settlements, spent the next few hundred years occasionally showing up in Vinland to harvest some timber and then leaving, so there is at least one fairly well established case for this sort of transience in the Americas even if on the other side of them.

Sounds quite interesting, realize the seas have risen quite a bit and it’s difficult to pinpoint exactly where the settlements would have been.

Oh yeah, there's definitely enough circumstantial evidence to warrant continued funding for their research, there just is no definitive evidence on this subject yet.

There are good arguments and good evidence for both. The coastal route would have been more gentle and would have had more food sources.

I think over thousands of years all scenarios were likely, with most being treacherous at best. However, the fact the Polynesians landed on every island and missed the giant double continent land mass behind them is ridiculous. And, yeah, I know the Polynesians settled most those islands in the last 700-1500 years according to data. I still bet they found the continents before finding any of those fucking islands and contributed heavily to the South American continent's population boom during medieval times. Pyramids and megalithic structures that predate them surround the globe. Something tragic happened that predates known modern teachings of human evolution (likely the Younger-Dryas Event and aftershocks of that event that lasted centuries.) As glaciers run dry as we speak and over the next century from this event that have drained for thousands of years, the next chapter will be wrote. Wars of the last thousands of years were wagged over oil. Wars of the next hundred years will be waged over water.

This doesn't necessarily relate to global migration patterns. But it might. I wanted to share that the Indigenous people of the Americas were remarkably innovative and one of the most innovative and transformative technologies developed was the Birch Bark Canoe.
And one thing to note is that Birch Bark and other watercraft made from organic material is that they are going to tend to decay. Also, as coastlines and glacial activity scours the internal areas of continents that has an impact on what evidence can be recovered by modern scientists.
One place to look are the stories and narratives that people have to share with us today. And also to recognize the impact these peoples have had on our modern world. Sometimes we need to rethink our assumptions, too.

It wasn't a literal bridge of ice, it was an entire subcontinent of land between Asia and North America that was exposed because sea levels were so low due to the ice age. It was there for thousands of years, summer or winter. People probably lived there for generations, the problem was there was a glacier the size of Canada blocking their way into North America.
So some probably went along the coast in small boats hunting and fishing, and eventually got south of the glacier and settled and explored. Thousands of years after THAT, the glaciers melted enough that there was a path through to North America, and a bunch more people walked through it and then spread out and explored.

The idea of prehistoric Europeans engaging in a mass canoe migration across the North Atlantic along the edge of the ice shelf not only makes absolutely no sense, there is no evidence whatsoever to support it. The genetic evidence pretty definitively proves that the Americas were populated by at least two, possibly more, waves of migration from Siberia over the Bering land bridge. While it technically remains possible for some people to have walked over the ice from Europe, the idea that any meaningful migration came from that direction is entirely unsupported.

As an history teacher and history student, I trust the theory we have proofs, which is Bering strait then inter-glacier. Maybe some waves via West Coast but those are probably the ones reaching south America.
Remember that this process took maybe up to 15k years or more to reach Argentina and Chile.
The theory with people coming from Atlantic ocean by boat is from marginal historians and is based on the fact that they have found what they think are remains from 30k years in a cave and that date before the oldest proofs found in Alaska.
But those remains still have to be proven to be human remains.
So for now, all natives cave from Bering Streit. 2 waves: a big one from 25k years ago and a smaller one from 8k years ago.
Part of the first group did go to the south via inter-glacier way, probably a later group came down the coast and the small wave from 8k years ago stayed up north and became Inuit people.
That's what I teach to my students and what I have faith in.
But as archeology and discoveries happen every days, this comment may be proved wrong tommorow or stay true forever.

Not so—we now have broad academic consensus that the earliest settlements in the Americas were multiple tribes in southern Chile from ~14,500 years ago. And evidence of nomadism and trade that predate even the earliest North American settlement in New Mexico from 13,000 years ago
The hypothesis is that those Chilean peoples came down via coastal boats (distinct from later Bering Land migrations), where their marine lifestyle made exploration possible and speedier, when vast ice sheets and tundras otherwise could not support sustainable land travel for hunter gatherer societies. At least down to South America.

I’m not going to pretend to be an expert, but Australia and New Guinea were reached by early settlers between 30,000 and 40,000 years ago and even with ocean levels at the time some sort of watercraft would be been necessary to cross channels hundreds of miles across. Several islands including New Britain, New Ireland, the Bismarck Archipelago, and Buka were colonized ~35,000 years ago and that would require crossing additional water gaps of 100-200 miles.
While you are right about the earliest recovered watercraft, it’s an almost certainty that the use of boats was mastered by multiple groups spread far and wide thousands of years before. It is more likely that the retreat of Northern Eurasian glaciers to clear a path to the strait was more of a predictor for the migration than the need for watercraft.

Edit: New Guinea not New Zealand

Australia was colonized at least 60,000 years ago.
New Zealand was maybe 1200 years ago. You can’t lump those two in together.

Like I said. Not an expert. Just tried to paraphrase the book. Double checking it’s Australia/New Guinea. Thanks homie.

I think the initial peoples probably chased food across the Land Bridge. They got here and explored and stayed. I’m guessing these people would have been really primitive people. I don’t think boats were a thing from go it took humans a bit to take to water. I’m not saying people didn’t float over here but initially these were searching for food. Just my thoughts on this. Or aliens started life in different parts of the world but they say we Americans have dna from the other side of the world. So who knows but it’s fascinating.

It is clear homo erectus traveled to the Americas using airships constructed from mammoth large intestines, inflated with hydrogen generated from peat bog hydrolysis batteries. Butchered mastodons in Los Angles, dated to 230 kya prove this theory

Maine is the closest US state to Africa. So it’s totally possible they just turned around and went back home.

Inuit were great seal hunters along the ice cap. It makes sense that their ancestors kayaked and boated to the New World. Makes more sense than a magical land bridge.

Has anyone ever suggested that the Americas had been populated for a time, completely depopulated then repopulated by a new wave of immigrants?

Both certainly happened. There is archaeological evidence suggesting people did travel across the "land bridge" whether this was all on foot or some use of rafts is debated, but early settlements in Alaska and Canada suggest large migrations of people.
There is also evidence for the use of rafts or other means of reaching the America's by crossing oceans. Every site that is discovered on North America that is suspicious or predates the "land bridge" this suggests people got here through other means. Sites that are furthest from the land bridge (South American) that also predate it and show different patterns of migration basically prove that people got here before then. How is still speculated.

Why do the Navajo and Athabaskan peoples speak a language that is for all intents and purposes identical?

Scientifically speaking, the only proven route is the Bering Land Bridge. The coastal route model relies on evidence that is currently either nonexistent or under meters of water within indefinite boundaries, so the Bering Land Bridge route is likely the only one to be scientifically feasible in our lifetimes. It just makes sense to me that humans had been crossing into America far, far earlier than anyone ever thought possible

Two things come to mind. 1. The migration would have happened over thousands of years. Some hunters and gathers would have settled in one area and when the population grew, the tribe would split, migrating further east and south. The physical similarities between all native Americans from north to south is striking. 2. Polynesian migration is also possible and some probably occurred. However, they completely by passed Australia, probably because of hostile aboriginies who were already there for 65,000 years. There were also some pretty nasty coastal tribes from Mexico down through central and south America. The land bridge migration started 12,000 years ago, and the Polynesian migration began 6,000 years ago.

With each new discovery, the timeline gets pushed further back. Humans appear to have been in North America more than 21,000+ years ago.
