    > As today’s world faces rising sea levels driven by climate change, the researchers hope to shed light on how Stone Age societies adapted to shifting coastlines more than eight millennia ago.

    Unfortunately I don't expect there is any particularly reusable solution to be uncovered. Ancient peoples facing rising tides almost certainly just walked a bit inland and built new huts there. They probably thought nothing of it. They were a far more physically mobile culture, without great dependence on immense, immovable infrastructure - nor on rigid land ownership rules.

    Our culture's migration will be entirely different.

      I think the problem is researches feel under pressure to make research of immediate relevance to get funding etc. Its value is it tells us about people and history.

      There are far more relevant examples in how more recent cultures dealt with things like land being lost to erosion or desertification or shifting rivers etc.

        I think the rigidity of land ownership will be put to the test because of climate change.

        • toast0 2 hours ago

          I think for a lot of people, their deeded land is in eventually in terms of lat/long, and if the water swallows their land or their land falls in the sea, they're pretty much SOL. Depending on the rules of their locality, they may keep ownership of the land that's now underwater: it may effectively cease if underwater land is not subject to private ownership, or it may continue but not be of value because you may not be able to exclude other people from the land (or the waters above it) or develop it.

          For some though, the deed may be defined in terms of the coastline, and then they're going to have an interesting legal battle. But this isn't without precedent; coastlines and waterways change and things defined against them adapt.

              That's not in terms of lat/long per se, but the section and townships are effectively equivalent to lat/long. If the shoreline moves, my property doesn't. Technically everything is relative to this stone ... https://en.wikipedia.org/wiki/Willamette_Stone

                    Land ownership was formalized about as soon as there was a reason for anyone to own land - i.e., as soon as any given people started doing pastoralism and agriculture.

                    • adamlett 8 hours ago

                      Possibly, but what we think of as land ownership today — land as a commodity that can be freely bought and sold, and as something that gives the owner near-total control over how it’s used — is actually a fairly recent development.

                      In feudal Europe, land could only be “owned” by a lord, and even then it was bound up in obligations both to their superiors and to the peasants working it. There were all sorts of customary rights layered on top: in Denmark, for example, nobles had a monopoly on hunting and timber in their forests, but peasants still had rights to gather firewood, berries, nuts, mushrooms, and so on.

                      Village fields were also often organized under the open-field system, where land was divided into strips. Each household got a mix of good and poor soil, and in some places those strips were even periodically reallocated to keep things fair. It’s a very different picture from modern private property.

                      • ahazred8ta 44 minutes ago

                        There were some premodern societies where land possession was very fluid. But. There were plenty of others where land ownership worked almost exactly like today's systems. The oldest clay tablets talk about buying and selling land, systems of laws protecting land ownership, court cases involving land disputes, and surveyors laying out stone boundary markers that were meant to stay put for centuries. Incan quipu cords were records of who owned which piece of land. Asian rice terraces have been individually owned for thousands of years. This urban legend that private property is not an ancient concept is really wonky.

                      • inglor_cz 9 hours ago

                        Even without formal land ownership, pre-modern societies were keenly aware about who exploits which scarce natural resources. There is just no way to cut scarcity out of human life experience.

                        For hunters and gatherers, it helped that their population density was relatively low. But there was still competition for good hunting grounds.

                          Western regulations about land appropriation are strict for a reason, and they always require just compensation for a reason. That is the only way to prevent powerful people from just grabbing what they want, cloaking the thieving act in word bubbles about common prosperity.

                            Maybe there could be some balance instead of "Either everything can be owned, or nothing is!".

                            It isn't impossible to move cities if it's really needed and someone is footing the bill, even in a democratic Western country that is famously highly regulated, like Sweden. Since a mine in the north is expanding, they have to move the entire city (paid by the mine's operator in this case), building by building, which of course isn't without complaints, but it's a thing that actively being done as we speak. https://www.bbc.com/news/articles/cde3xp4xlw9o

                              It's a small town of 17k and they expect to be done "moving" (really just building a whole new town 3km away) by 2100. That's not a scalable process.

                              For a more likely scenario, see Japan. Demographic crash (which is already happening all over the developed world) followed by mass migration to urban centers with economic forces dooming or favoring a city depending on it's circumstances (looking at you, Miami).

                                  I don't really mind takings for very good compensation. If you want to uproot people in the name of X (say, a railway that cannot really change its path, or a very valuable mine), pay them some low multiple of the current market price of their property and off they go. The part with the market price helps them buy property elsewhere and the extra part is sugar to compensate for injured feelings. (It is not easy to abandon a home if your family lived there for generations, and we should account for that.)

                                  But such situations are relatively rare. Perhaps the mine in Kiruna is worth it and the corporation/government can pay for the compensations. Same for vital ground communications (highways, railways).

                                  If it isn't, though, then let the ore in the ground and let the people live where they built their homes.

                                  Most of the time I hear ideas about "flexible ownership" etc., upon further discussion, the person starts talking about outright expropriation from people they don't like.

                                    That’s a limited population being moved for high value resources. This option does not scale for large populations. It’s easier and cheaper to rebuild.

                                    I don't think it's fair to pretend the only options humans have are the extremes of private and state ownership. Greed and the weight of capitalism under rail expansion in the US completely obliterated at least 15-20k years worth of Indigenous "non-rigid land ownership", being the apex system of human power consolidation and all that.

                                    Native American nations and tribes didn't "own" land in the way that European colonizers did, under a doctrine of private property, written deeds and legal systems. Even under tribal territories, access was fluid.

                                    America and its land was held communally by tribes and was generally understood in terms of use rights. If your nation, family or tribe cultivated a field, you had rights to that field as long as you actively used it. And stewardship of the land was seen as something to care for, not a commodity.

                                    And this was the way things were in America up until a few hundred years ago.

                                          Borders are very much not a new concept. Nations are new-ish but not the idea of owned and protected land.

                                            Control of borders was nowhere near as tight as today, given how underdeveloped technology was compared to today, and in some places (deserts, forests) the border was more of a very wide strip of no-mans land than just a line.

                                            But places like the Roman Empire absolutely had "hard" demarcations in some places, not just standard country borders, but also internal borders.

                                            For example, when Caesar crossed the Rubicon, he legally crossed into Italy by doing so and thus triggered a war. Rome itself had pomerium, a city demarcation whose crossing had legal consequences as well.

                                            If you entered the Roman Empire peacefully, and you had something to tax or apply duties to, you would be confronted with officials in the closest suitable place.

                                            That sounds like border to me.

In Big papers the stories were more like fiction - using some fact from the real event as inspiration. It was surprising that local papers can't even get simple local news right. Only once I think the local paper got into a little bit of trouble. They wrote some nagging critic about the performance of some school theatre - but the event had been cancelled...

                                                        I never understood the war graves thing. On land, people go to great effort to recover the bodies and re-inter them in proper graves. In the sea, they get designated as graves and nothing can be salvaged.

                                                          There aren't many spots on land a body can wind up that are comparable in difficulty to access as thousands of feet underwater.

                                                            I know. But for those that can do salvage, what's the problem?

                                                              You'd have the same problem if you tried to salvage topsoil from a cemetery.

I know immigrating to Denmark is nearly impossible, but I keep telling my partner that if (or when) the political situation in the US deteriorates sufficiently, Aarhus should be our destination -- that or Copenhagen.

                                                        Immigrating to Denmark is actually pretty easy if you have the right kind of education or get offered a job with a high enough (~$65000) pay. See the "Pay Limit schemes" and "Positive Lists" on this page: https://nyidanmark.dk/en-GB/You-want-to-apply/Work

                                                        And as a reference, $65000 would be considered a preposterously low salary for a new STEM graduate in Denmark.

                                                          I've lived in Aarhus for the past two and a half years, and can say that it is quite a nice city to live in. Very walkable, decent public transport (despite how much locals love to complain about it), plenty of restaurants, bars and other entertainment. I'd definitely recommend it.

                                                          Moving here was quite a bit easier for me though, as I'm an EU citizen.

                                                            Will have to dig deep for interesting, non-Trump related US news.

I read three national news outlets and one specific to my local region of Østjylland a couple of times a day. I wonder if I should swap some of them.

                                                              Something that's stuck with me is the time I walked into my local bookstore and found banners advertising that a new book by Orson Scott Card was already out and available for sale then and there.

                                                              Pretty much any other type of product (that I might buy) would have managed to publicize this to me well in advance of the day you could purchase the product.

                                                              To your question, I think the types of content delivered by the publishers you read are unlikely to change, and if you want to start hearing about new types of things, you'll need to find sources that cover them.

I follow that, 9 minutes per day and that's it for politician news for me. I just ignore anything else, politicial or world, knowing I'll find out about it anyway if it's important.

                                                                    But you can also just cut out news completely. There are edutainment channels on YouTube you could follow instead. You have hacker news. I watch other sources, just not "newsy" news.

                                                                    There is one VERY IMPORTANT rule for choosing channels/podcasts/content to watch. I only watch people presenting with positive energy, in a calm manner. "Scary" way of presenting, or clickbaity titles give more followers, but I feel bad from watching them. Just like when I'm low I sometimes play an audiobook read by Eckhart Tolle. I wonder why it makes such a difference?

                                                                            There will be much happening for the next decade or two. New wars, new alliances. Countries agreeing (or disagreeing) on new influence zones.

Look at how Putin makes fun of Trump, playing a delay game, while he is trying to slowly win the war he lost (by not winning it in 3 days).

But due to variations in local conditions it's really tough to systematically investigate: every site has to be treated individually. Plus doing anything underwater becomes at least 10× harder and more expensive. Human scientific divers can only work easily down to about 30m: anything significantly deeper requires commercial diving protocols, submersibles, or ROVs which raise the difficulty and cost even further.

                                                                                    • erk__ 14 hours ago

Especially around the Mediterranean including the north coast of Africa and the southern horn of Africa. Ancient humans are known to have inhabited the southern tip of Africa into the last interglacial period, and human migration across and settlement in the occasionally green Sahara could explain some things.

The white sands footprints push things back far enough that virtually all coastal sites would have been destroyed by glaciers at the LGM. We're still trying to map out the specific details.

But even if that was really 20kYA+ (wild that this is a serious possibility now!) there's still a vast gulf of more recent prehistory that we know so little about. And there's probably loads of fascinating evidence to uncover.

                                                                                                          The first communities started to settle more or less after the ice age ended, the sea level had risen and the planet had a more pleasant climate around 10000 years ago (source: I'm not a professional on this topic, just summarising what chatgpt tells me)

They depend on them a lot more; need to know where to move next to find good food sources for the current season. Plus, it's not like these people haven't had sacred spaces that they visited, which requires knowing how to get there from wherever you currently are.

A city of ~1000-1500 (some sources say 3000) inhabitants that was drowned in the Grote Mandrenke (1362 AD). That's a very big city in that time. In my childhood we were told, while wandering the tidal flat, that we should listen closely if we could hear the church bells under the mud. Only in 2023 the whereabouts of the sunken city were definitely confirmed and mapped. "Rungholt" probably means "wrong/low wood".

                                                                                                              I have a book on Greek mythology that takes the position that Hercules, including his name, is considerably older than most of the Greek pantheon and should be thought of as a foreign import. But the form of his name ("Heracles") looks so natural in Ancient Greek, "glory of Hera" in the same way that you see other Greeks named Agathocles or Themistocles, that the mythology around the relationship between Hera and Heracles, which is extensive, must have developed from that apparent similarity.

                                                                                                              Potentialities like this keep us on our toes when we look at names like "Rungholt".

It is possible that Rung here could mean stanchion/post (so for wood that makes strong posts), but unlikely so close to the sea, is it not?

                                                                                                                I get what you mean, though. Here is a village called Großenwiehe, easy to be translated as "Great Consecration", and that was the commonly accepted meaning. Only much later it became apparent that "-wiehe" probably came from wighæ, so "Great Fortification". And in fact the old fortifications are still visible today.

                                                                                                            • vintermann 14 hours ago

                                                                                                                Does DNA in bones survive long term in seawater? Intuitively I think it would "wash away", or be hopelessly contaminated with other DNA in the water.

Wood is preserved much better in the salt water than on the ground (unless it's a desert).

                                                                                                                    What I don't understand is how it survived the surf. 2 meters per century means that the place had spent a century in the surf line, and surf grinds everything into sand and dust and scatters what it can't grind. I would have understood a sudden flooding but this is surprising.

                                                                                                                    • pfdietz 16 hours ago

                                                                                                                            They are found from Portugal all the way to Siberia, but very little is known about them following the Christian meme eradicating the indigenous cultures through the many purges and programs from 300CE on.

                                                                                                                            There are some references that imply at least in some places they were a kind of connection to the afterlife and ancestors that would turn into birds that would perch on top of the standing stone, something that is still part of indigenous beliefs and practices in parts of Asia. It's basically the indigenous culture of the Native Europeans that middle eastern Christianity destroyed and eradicated like it destroyed and eradicated the Native Americans and so many other native people and cultures around the world.

The Wikipedia article suggest that early Christians defaced and destroyed some of the stones, but knowledge about the people who erected those stones was lost way earlier than 300CE.

                                                                                                                              • hopelite 7 hours ago

There is clear evidence that the practices of ancestors worship and their ancient practices involving these stones was directly linked to Christian persecution, including documented examples of the progroms against the indigenous Europeans starting immediately following crusades and effectively being part of them.

                                                                                                                                • jalk 6 hours ago

Also I've never before heard about Christian crusades earlier than the late 11th century one started by pope Urban II. Perhaps you are thinking about peoples like the Wends in Arkona (Slavic "pagan" tribe in northeastern Germany), who were force converted into Christianity in the 12th century. If they somehow were worshiping the stones in question, then that sounds more like retrofitting existing ancient monuments into their own religion, rather than keeping some ancient knowledge alive.

Christianity did the same here. There is one case where they filled up the tunnel and build an monastery over it. Excavations and carbon dating revealed quite old objects dating between many thousand years. Some stones especially the ones in the entry area are big and heavy cut outs, the tunnels are often cut into stone. It’s still an unsolved mystery.

                                                                                                                                Heinrich Kusch[1] and his wife have done very interesting work regarding this.

It’s amazing when you start building a mental model of just how pervasive and expansive this whole system and lost, destroyed culture gets. I do find most explanations for the various “tunnels” rather dubious, especially the more “modern” seemingly medieval ones, but it’s all a very interesting topic. The indigenous European history and culture is immensely suppressed.

                                                                                                                                  Something I only learned well into my adulthood is that one of the reasons you can dig down and find the foundations of one, sometimes two different cultures below the feet of cities is that they used a lot of mud bricks, and when the house started to molder and fail they would pound it flat and start over, not haul the whole thing away. So a couple times a generation a neighborhood would be higher than it was before.

                                                                                                                                  And the center of the city would be on a hill, and keep getting higher (even if expansion kept the slope roughly the same). Over time it would become more and more work to get to the middle of a city from the plains surrounding it.

                                                                                                                                        The question is whatever time period people discuss, somehow the indigenous people is whoever was there exactly before the time they mean. But people have moved around all through history and killed each other the whole way through so it's always strange. Almost as a rule the "original" indigenous people were killed by the "current" indigenous people sometimes not that long ago before the period under discussion. It think it's better to just use the terms for both groups. Also because it's a bit weird to relegate the conquered group to just "the indigenous", they have a name too.

                                                                                                                                        I understand using the shorthand for encounters of two groups with very disparate technology knowledge like for example during the Discoveries period but when it's so long ago and people had access to "same" stuff it's a bit weird. My comment isn't a slight on the less powerful people it's weirdness with the term.

                                                                                                                                        I think you are seeing this a little too 2d. The reason the Christian meme spread so well is more complex than that. A codified belief system written down, the thought of a God that loves and cares about you, a path to redemption and forgiveness for sin or mistakes, these are just some of the reasons that it has been so successful. It wasn’t always just forced on people although there was that too. It’s just a really good meme and great story when you get to the heart of it. The people meeting in secret when Christianity started and risking their life to do so weren’t forced into it at all. Like capitalism, Christianity fits a lot of human needs and desires that are hard coded in humans.

                                                                                                                                          Which version are you talking about because there is no one definition, Christians cant even agree amongst themselves about Christianity. Anyone is free to make up their own religion, include the bible in the lore, and call it "Christian".

                                                                                                                                            My impression is that Christianity took over Europe more for political reasons than the good story. There were strong incentives for pagan rulers to "convert", and force it onto the populace.

                                                                                                                                            I agree that the good story is key to its staying power.
