This theory holds that humans in different parts of the world are primarily descended from local hominids vs the commonly accepted theory that humans are all primarily and recently descended from a population somewhere in East or South Africa with a small amount of admixture with local hominids.
Most people consider the multiregional origin theory highly motivated reasoning and also completely garbage science.
As I understand it, it's somewhat encouraged by the government. China's the sort of place where, if the government has a preferred wacky theory, one may be inclined to smile and nod rather than arguing.
In western democratic countries, the government doesn't typically exercise very much control over academia (and in fact academia is a huge source of criticism of the government and its policies in most such countries). There are exceptions (eg that thing recently where the government of Texas harassed an A&M academic over criticising His Holiness the Lieutenant Governor) but that was exceptional enough that it got significant news coverage, and the government of Texas is definitely on the dysfunctional end of western democracies.
somewhat similar to the demonization of communism that the west pushed for decades?
Apparently there are many people that are more incline to just smile and nod rather than arguing. Probably the geographical location of these is not really important. They're equally distributed across the globe
Yes I'm taking about that, you're the only one that understands it apparently.
The thing is that my comment couldn't be anyhow related to today's situation (I've used the past tense) since communist doesn't exist anymore (not the way it used to) and most of the country that implemented it widely abandoned it (probably the only exception is perhaps North Korea)
I don't understand why people get so emotional when you mention the word communism
It was a simple comparison point on the previous comment that, by my standard was also wildly off base (given that he said dumb to a whole country basically)
the fact is that the west seems to be so attached (weirdly) to communism despite even those who implemented it already abandoned.
What an idiotic question. In my case, the sensitivities are familiar. My ancestors in Ukraine were starved to death by communists during the Holodomor. Is that something you're familiar with?
The West is "weirdly" attached to communism for many reasons, the foremost being that the past 50 years has been spent trying to clean up the mess left by communist regimes.
Do you ever stop and wonder what Russia could have been like had the Bolsheviks not terrorized it? Does it scare you to face just how badly your ideology has globally failed, and will be forever remembered as a point of shame in the grand story of human development?
I'm glad you mentioned that! Plenty of Wikipedia users much more knowledgable on the topic than you or I had a lengthy discussion on whether it makes sense to try and make such comparisons.
> somewhat similar to the demonization of communism that the west pushed for decades?
I'm not sure what you mean with 'the west', but in Western Europe communist political parties were allowed just like any others.
When I went to high school in the 80's it was even kind of fashionable to have communist sympathies. This was before the fall of the iron curtain though, once it went down it became clear how terrible communism had really been.
that doesn't make it less demonized. Unless you forgot the media campaigns on it and the plenty of wars that started in the attempt to stop the spread of communism.
No, because the government doesn't need to demonize communism to make it sound dumb. Hell if anything, the contrarian nature of Americans caused many to entertain the idea after witnessing the demonization, which makes it basically the opposite of China's situation.
it doesn't matter if I've experienced it or not. My comment it's not a praise to communism, perhaps just read it again (and read the context from which it started too)
As somebody who intimately saw on my closest ones and everybody else various horrible things that communism does to society and every single individual in it, and how the legacy of it can't be shed easily even after decades and multiple generations, you don't need to demonize communism a slightest bit .
Just point out well known facts, in balanced manner, and that's more than enough.
After a lifetime of being on the boot end of capitalism, I don't think communist systems are special in being full of horrors. I don't think the particular system humans use to justify those horrors is the issue.
You don't think... well experiencing both systems would give you much better opinions to compare rather than just thinking about it. Unfortunately I had, and my opinions are clear.
You can see it yourself if you look closely enough, go to let's say Vienna, and then go to Bratislava or further east. Even after 34 years. I don't mean financial aspect of difference, I mean everything else that makes healthy society thriving.
In capitalism, you always have freedom of thinking, traveling, freedom to not have a job for example. You can bash it as much as you prefer, and its leaders. Your parents won't be put in gulag or uranium mines for 10 years because of that. My friend, you frankly have no idea what you write about...
This kind of whataboutery is an ignorant and insulting to people who’ve actually had to live through the horrors of communism, which are on a different order of magnitude to the horrors of capitalism, bad as they might be.
I have yet to see a single example of a horror done under any modern human system that wasn't done under every system before and next to it. If I'm ignorant, it's a failure to persuade on the part of people who have a special hatred of communism.
Sure, tell that to the relatives of the 4 million Ukrainians who died during Stalin's farming reforms, to the 2 million Chinese who died during the Cultural Revolution, or to the 2 million Cambodian victims under Pol Pot.
I could rattle off a list with similar numbers for capitalism (or proportional numbers for older systems), too. This does not persuade anyone who isn't already in the choir that your pet gripe is special.
Humans do horrible stuff to each other in the name of ideology. Systems are just one of the ways they rationalize it.
The "demonization" of communism is wholly deserved. Every communist country, ever has been am impoverished, totalitarian, shithole. The most successful "communist" countries are those that have given up on economic communism (China, Vietnam), though they'd be even more successful if they gave up on political communism too.
The track record of communism is so insanely bad that it is literally the second worst ideology of the 20th century, beat only by facism which caused the instant self-immolation of every country to ever try it (while inflicting terrible harm on their neighbors).
The only scientists Chinese people are approved to listen to are most likely to stay within the party line and the ones who aren’t are smart enough to not be very vocal about it, it won’t earn them any gain anyhow and may otherwise attract unwanted attention from authorities. In China you can easily be summoned in by a local police and get harrased. It’s just how it is in totalitarian states.
So I think it's true that China is, for a totalitarian regime, relatively science-friendly on high-stakes stuff (or, at least, it is _today_; it very much wasn't in the Mao era - see the whole War on Sparrows thing). Archaeology (with the exception of its intersection with climate science) is relatively low-stakes, though; the downsides of getting it wrong for ideological reasons are limited.
I find it interesting on what totalitarian regimes choose to put their foot down on. At some point I think the topic almost doesn't matter and it serves as as just a battle of wills where the authorities are please that they can impose whatever, and it also serves to separate their people from the rest of the world and create their own little "culture war" barrier.
When it comes to Archeology I always find it a bit confusing too. I doubt some randos from thousands of years ago would identify much with modern nation states, ethnic groups or etc, and yet that's often how arguments about such things go..
Archaeology’s a surprisingly common one. Rhodesia on Great Zimbabwe is another example of this; the nature of Great Zimbabwe was uncontroversial outside Rhodesia, but the conventional view could get you in trouble _in_ Rhodesia.
Even in democratic countries, you sometimes get a degree of weirdness around archaeology and to some extent geology; during the Bush II era, some pressure was put on US national parks to push creationist stuff, say (doesn’t early-noughties right-wing behaviour seem quaint, now?)
Most Chinese have probably never given a thought as to whether they are pro science or not. That seems to be more an American preoccupation. My Chinese relatives have all sorts if unscientific beliefs based around food and folk superstitions, and they are highly educated.
This might be well true, but they are also likely to believe science as well. It's just the two live in an easy parallel where one isn't necessarily valued over the other-- good or bad.
In the US the camps are FIRMLY pro or against science or many other topics, so things get alot more polarized.
I don't think US camps are anti-science as much they are against a small subset of science which disagrees with their religious beliefs. There are no anti-relativity or anti-magnetism groups as far as I know.
In China there are plenty of anti-vaxxers as well as a large number who would balk at anything implying being gay is biologically normal. They can't really form groups for this sort of thing, obviously, so you don't hear about it as much.
> As part of the Values and Beliefs Survey, Gallup called a random sample of 1,028 landline and cellphone users and asked them which of three descriptions most closely matched their beliefs
I lived in China for 10+ years. Most recently a few years ago. Lived in the US for 20+ years.
In China, I never met a single person who was anti-science. None.* Everyone knew that to get ahead in life, they had to get educated. Part of that education requires learning sciences.
Meanwhile, in the US, anti-Science is part of the culture. It even starts early in school. In the US, if you liked science as a kid, you were labeled as a nerd or uncool. In China, being good at science in school gave you more social status, not less. In the US, religion is also a huge blocker for many towards sciences. In China, people aren't religious at all or that their religion does not contradict with the sciences.
I think people here see how far behind China was in the 19th century and conclude that people there must be anti-science. China had different reasons for being far behind in science in the 19th century. Being anti-science is not one of them.
* I should clarify that of course there are people in China who are anti-science. I’m mostly referring to “normal” people. IE. people who contribute to society, have jobs, went to college, etc.
There is a big area in the middle between pro- and anti-science. And what you describe is more pro-education than pro-science. Education and science are not the same, even if it includes knowledge acquired by science. And we know from all around the world, that even well-educated people, even scientists, can fall in the intellectual pitfall of myths, superstition and strange unscientific theories and maintain both worldviews side by side.
> In China, I never met a single person who was anti-science. None.* Everyone knew that to get ahead in life, they had to get educated. Part of that education requires learning sciences.
That’s a pretty crude definition of “pro-science”.
As a nerd that did break out of that label, let me tell you that if you had any emotional intelligence or social skills, you don't lose social status in American schools for being smart, in science or any other subjects.
If you did other 'cool' things successfully - perhaps soft rebellion against teachers or administrators, music, athletics, parties, dance or cheer, or were physically attractive (took care of yourself and followed basic fashion), and had good social skills you don't stay at the bottom of the social ladder here, even in the Social Darwinism of middle and high school.
Competency and accuracy are the lowest form of interpersonal skills. If no other interpersonal skills or interests are cultivated outside of science, even the most competent and accurate individuals are likely to fail socially, which will also effect their career outcomes. Competency is used too often as a display of dominance or defensive mechanism. As bragging. As self-delusion. Connections with a diverse set of people outside of the competency only group will increase social skills and status, and with those connections comes a higher chance of success.
The people who are labeled nerds and derided for it constantly generally do not try or care to try to make these outside connections for fear of ridicule or oversensitivity, and occasionally physical safety. Non nerds see this as a superiority complex, and find overly sensitive and defensive people difficult. So they are devalued socially.
That is to say - make lots of friends and cultivate various interests outside of your core interests. Be interested in others and their accomplishments. Engage in the social jousting and own being the butt of a joke every once in a while. Don't lean on intelligence and academic achievement for everything. You don't have to win every debate to prove how smart and deserving to lead you are. You have more value than just being right all the time.
These values fit our American cultural ideals, where our leaders are typically selected on the basis of all their skills rather than a singular aptitude.
You are confusing being a user of scientifically-derived knowledge with being a practitioner of scientific principles. The former is just another belief system without the latter.
Your original statement was about the whole of the Chinese population. Your latest statement is about scientific output, which is driven by a small subset of the population. The two are not necessarily related.
That was my point. OP made it seem like China is an outlier because its 100% pro-science or something, when they have their superstitions and conspiracies just like the population of any other big country.
I mean my family has lived for at least 300 years in a region close to where the neanderthals were first discovered. I assume I have some of those genes in me
Apparently East Asians have more neanderthal DNA than Europeans so I'm not sure the region of initial discovery really matter that much. Also Neanderthal 1 is 40000 years old, your family may have arrived in the region even a 1000 years ago and be completely unrelated to it.
It works the other way too though. There's a good chance that at some point along those thousand years, somebody had kids with somebody else who had older ancestry in the area, and so on.
Most europeans do have significant amounts of neandertal DNA, but the likelyhood of your people 300 years ago being in the same place in europe that long ago, even a thousand years ago, is slim. There’s been massive migrations and demographic shifts. The most “ancient” population in Europe I believe are thought to be the Basques.
East Asians have the most Neanderthal DNA left in them. [0]
Regarding Denisovans:
A 2011 study found that Denisovan DNA is prevalent in Aboriginal Australians, Near Oceanians, Polynesians, Fijians, Eastern Indonesians and Mamanwans (from the Philippines); but not in East Asians, western Indonesians, Jahai people (from Malaysia) or Onge (from the Andaman Islands). [1]
Well, it's true in that the predominate theory is "humans are all primarily and recently descended from a population somewhere in East or South Africa with a small amount of admixture with local hominids" but the multiorigin theory is pretty much always brought up in the context of implying that different human populations are actually different species.
The biological definition of species includes reproductive isolation. Two different species mean normally some kind of reproductive barriers. In this sense, if two diverging groups of animals X and Y mate and the offspring is fertile they are still in the same species and will split sometime in the future. How we define the splitting time is the problem. Neanderthals and sapiens are only partially fertile, so by definition were two different species that diluted into one. Red hair and green eyes are consider Neanderthal contributions. Modern sapiens is clearly an hybrid.
But the field has gained a lot of complexity in the last decades. There are ring species, and cryptic species, and sometimes the DNA of a parent is entirely discarded. Changing our point of view is possible with better data, except that we need to find this data first.
Not necessarily a clone because sometimes happens in several steps. For example, horse x donkey hybrids are sterile in principle, but if just by chance they produce an ovule keeping only the DNA of one of their parents, it can be fecundated. A female mule can deliver a foal that is either a pure horse or a pure donkey, never another mule.
Maybe it's a good thing to consider different races to be different species. I personally think it will cause people to be more open-minded towards the plights of animals. Acknowledging diversity doesn't mean we have to hate the other kinds.
> two humans differ, on average, at about 1 in 1,000 DNA base pairs (0.1%). Human genetic diversity is substantially lower than that of many other species, including our nearest evolutionary relative, the chimpanzee.
> Groups of chimpanzees within central Africa are more different genetically than humans living on different continents
> Our genetic homogeneity implies that anatomically modern humans arose relatively recently (perhaps 200,000 years ago) and that our population size was quite small at one time (perhaps 10,000 breeding individuals).
> approximately 90% of genetic variation can be found within [continents], and only about 10% of genetic variation separates the populations.
Calling us different species is laughable. We’re the genetic equivalent of putting 2 rabbits in a box and opening it up to find 300.
Didn't the human population drop to something like 2000 individuals at some point in history? Would be like dropping 2 rabbits in a box and opening it up to see 4 million.
I wish I was as optimistic as you. I personally think people would be too preoccupied planning the elimination of the other human species to consider animals with greater respect.
That being said, Noah Yuval Harari has very forward thinking writing along these lines. He uses the context of potential AI superior to our own intelligence, and how they will treat humans, to advocate for animal rights.
Sadly, separating humans into different species would further delineate the "other". Opening up the asinine argument of genetic superiority, the "others" as a less evolved species, and just reignite eugenics.
Acknowledging diversity doesn't mean we have to hate the other kinds, but it's sure a convenient excuse if you're looking. And there are always people looking.
Xi Jinping has been on a quest to strengthen the ethnic identity of China, specifically the Han Chinese ethnic group, and this is probably part of it. If you look at the immigration policies of China, you'll find that they are some of the most restrictive in the world[1]. It is almost impossible for a Non-Chinese person to become a Chinese citizen. From what I've heard from people who know people in the Xi Jinping administration, they are embracing ethno-nationalism with incredible zeal. There's also a lot of ethnonationalist propaganda in China right now and western commentators have taken notice[2]. From what I've heard through sources, they're preparing for a future where it's eventually a zero sum game between China and the rest of the world, especially with regards to dwindling energy and other natural resources. For example China built six times as many coal plants as the rest of the world combined last year [3]. There is a huge denial of this in the west as westerners believe that racism and communism are incompatible, and at least China says it's communist.
> China serves as home to 56 official ethnic groups. The largest group, the Han, makes up over 92% of China's vast population, and it is the elements of Han civilization regraded as "Chinese culture"
There is serious oppression of ethnic groups inside of China. Things have been changing fast under Xi.
>Xi Jinping has celebrated majority Han culture as the timeless “soul of the nation”, gradually shifting ethnic policy from formal inclusion of 56 ethnic groups to cultural nationalism. Influential political economist Hu Angang called fusion a means of making China a strong and prosperous state again, while anthropologist Ma Rong considers “teaching barbarians” a revival of imperial tradition. These arguments emerged following mass violence in 2009, sparked by the murder of Uighur labourers by Han colleagues in a Guangdong factory accused of using coerced labour.
> There is a huge denial of this in the west as westerners believe that racism and communism are incompatible, and at least China says it's communist.
I don’t think westerners put a lot of stock in China’s claim to be communist, nor do I think many westerners would deny that it’s an ethnonationalist country.
I think that’s an over-generalization, but it also doesn’t really address what I said. Whether or not they’re opposed to it, westerners know that China defines itself as a country for Chinese people. Americans have all heard of the Uyghurs.
My bet would go to racism. China seems to very guilty on that regard, and racism against Africa and especially black people seem to have rose again on the last years.
Most people meaning most people who have an informed opinion, because the evidence (archaeological, genetic, etc.) is so ridiculously in favor of the out of Africa theory. You have to be at the denial level of “evolution is just a theory” to think otherwise.
From your wiki: "In its revised form, it is similar to the Assimilation Model, which holds that modern humans originated in Africa and today share a predominant recent African origin, but have also absorbed small, geographically variable, degrees of admixture from other regional (archaic) hominin species"
> Most people consider the multiregional origin theory highly motivated reasoning
As if the Out of Africa theory isn't highly motivated?
> and also completely garbage science.
But genetic evidence has proven that we all have different hominin dna. Science backs the revised multiregional model.
This reminds me of the clovis theory. The agenda driven people always front run any criticism of the clovis theory because they were on the wrong side of history and science.
My understanding, sorry for not having links at the ready for all this, is that many studying this currently think that Cro Magons, Neanderthals, and Denisovans all mixed to varying degrees at various times and emerged from a complex mix of pre humans like Homo Naledi. This makes the ancestry of Homo Sapiens more complex than simple lines of descent. Genetic analysis of these groups suggests that there was a third group that mixed with Neanderthals and Denisovans which has not yet been identified. None of this relates to the multiregion origin theory that you mention.
As populations from different regions have different levels of admixture from Neanderthals and Denisovans, the multi-regional origin hypothesis is validated.
That's the Assimilation Model. Both Multiregional and Out of Africa were wrong (or more accurately, incomplete), but Multiregional was probably a fair bit more wrong.
There’s actually a decent amount of evidence that points to it. I’m too tired to find it now, but humans didn’t descend from apes, instead we have a common ancestor that goes way further back
Humans didn't descend from apes. We are apes. Taxonomically speaking we are in the Hominidae, or great ape family. It is comprised of 8 extant species of which we are one of them.
If right now we found a weird island with a population identical to that "common ancestor that goes way further back", the general population would label that ancestor as an ape - while it's not the same as any of the modern species of great apes, they were morphologically similar to primates as such, not something totally alien or conceptually different.
You might want to debug your process for figuring out which information sources to trust because "humans didn't descend from apes" is about on the level of "birds aren't real"
I also, like the person above, heard we're not descendants of apes and, while it seems odd, took that as my best available knowledge.
I never considered that this makes a ton of sense: of course we didn't evolve from apes, after which the apes just stopped evolving and froze their DNA and never had mutations again. Of course they'll be different from their ancestors. But that doesn't mean that our common ancestor was an alligator or something and we developed all ape-like features independently of each other. That's what I took it to mean (when I heard this, idk, maybe as a teenager more than ten years ago), but your comment makes a lot more sense.
We didn't just evolve from apes, we are apes. Just as we are animals. But obviously we also frequently use the words "animals" and "apes" with an implied "non-human" qualifier. And yes, almost certainly any common ancestor of both human and modern day non-human apes was likely to have been just as different genetically to us as it would be to our primate cousins, though obviously it's possible genetic change occurred more rapidly in one branch vs the other.
Could be. In my language, we don't differentiate between monkeys and apes. (Like how in English you call any lightness of blue blue, but not any lightness of orange (darker: brown) or red (lighter: pink). Russian would call the blues, sinii and goluboi, as different as orange and brown are to us.) I couldn't tell you the difference in English, so I probably wouldn't have remembered if it was one or the other ...if I got the information in English in the first place
It's just a weird argument to make because nobody is claiming that we are descended from chimpanzees, monkeys, etc. As far as I know from history, that same strawman argument was used extensively during the evolution debates of the 1930s in America.
It's a place to tread carefully in the context of discussing a multiregional human origin theory.
I can't read minds but they may have intended to point out that while humans did not evolve from any of our modern cousins (modern apes, modern monkeys) we all evolved from some common ancestor (generally classed | accepted as an 'ape' albeit not a modern one) and it's conceivable that common ancestor may have had its own diaspora from which various human groups evolved in differing regions of the world.
Not my argument, mind you.
This all being distinct from Snopes trial era memes, etc.
That widely dispersed ape we evolved from is already a well-established species called Homo erectus.
The conflict this thread is discussing is between the (strong) multiregional human origin model (MRO/MRE) that used to argue that these aboriginal are where modern dispersed populations come from. This view is now considered completely dead on the basis of genetic evidence alone, with dozens of other lines of evidence refuting it. Weaker versions still exist though.
The oppositional view was that humans evolved solely in a small part of Africa and spread from there, with no little/no admixture from other archaic humans, called the recent single origin model (RSO). This view is not widely held today either.
Modern anthropologists and evolutionary biologists usually believe that humans evolved out of a complex mix of archaic humans broadly distributed across Africa into anatomically modern humans (AMHs). Eventually AMHs left Africa and admixed with other archaic humans in a fairly minor way, forming modern human populations. Differences between academics usually come down to what they think of that within-Africa population structure, or thetiming/significance of archaic admixture. Chinese academics tend to follow in the footsteps of Xinzhi Wu, a prominent Chinese academic that was a strong MRO advocate before his death. That includes the authors of this paper.
I largely agree save I'd describe Homo Erectus as mildly dispersed (from my perspective and to the best of my current knowledge, admittedly a few years out of date), never having gone deep into Europe, Mongolian steppes, the Americas, Northern China, the Sahul (Meganesia|Oceania), etc.
Given the reference to a common ancestor, I suspect that they means something more along the lines of "birds aren't reptiles", which is or is not true depending on what you mean by "reptile".
There’s no major difference between a chihuahua and a German shepherd in the same way there’s no major difference in “insert your X & Y breeds here” - it’s pathological to think that there isn’t a bred phenotype exposed within a population cluster.
Pure imbreds in dogs end into retardations and dangerous genetic illnesses. There's no 100% pure dog... with a good physical fit. Deal with it.
The same with humans. Read about the "sleep illness".
What’s different enough? There’s clearly physical differences of magnitude and measurement.
I’m saying dogs have “races” - yes, just as humans do. Whatever you call that grouping it is based on the comparison I made on my original post which is logically correct.
Don't know much biology, but appears "modern human biological variation is not structured into phylogenetic subspecies ('races'), nor are the taxa of the standard anthropological 'racial' classifications breeding populations."
"'Race' is a legitimate taxonomic concept that works for chimpanzees but does not apply to humans (at this time)."
You don’t need to be a biologist to know that when you bring a chihuahua to a dog park you go to the little fenced section compared to the bigger section for the bigger “breeds” and as a human you marvel at the sight and fact fact that they’re biologically the same species yet clearly with defined differences. Perception of reality allows you to infer boundaries and collections of similar things, words in a paper to justify what reality demonstrates physically and clearly is not only an appeal to authority and a fallacy of argument but it’s also meaningless as it’s out of context and can’t possibly refer to a shared experience of reality.
If we use the current definition of species, humans can reproduce with any other human in the planet, therefore we are at this moment the same species. We are probably too promiscuous to expect otherwise.
That's not the definition of species. In many cases different species can reproduce together, e.g. wolves and coyotes. In other cases, species are asexual so clearly there must be some other way of distinguishing them besides sexual compatibility.
The actual definition of species is essentially arbitrary and, when applied to humans and the possibility of different human subspecies or species, the question is essentially political.
It becomes even more obvious when you look into previous proto-human groups like neanderthals, denisovans, etc, as far back as you want; one can ask what counts as a subspecies, what counts as a species, and struggle to apply that in a self-consistent way today between Chinese, neanderthals, Australian aborigines, African pygmies, denisovans, native Americans, etc.
Don't let anyone trick you into thinking there is some clean science answer here - biology is far too messy.
Eh, there are, but not sorted by skin tone or location. If you consider a situation as "home" (the species cycled through crisis/conflict every generation), certain neuro-types pop out as adaptions to this situation cycle parts. A shizophren might look out of place in SF, but he might call us out of place in a warzone.
Its not a good thing though and hardly something to claim pride from or for. Nobody wants to be on team wheel chair.
I'm not an expert, but no-chin and that reinforced eyebrow area looks like the definition of a Neanderthal. A word that is strangely avoided several times, and does not appear in any part of the link.
Why is this so different as to claim a third entirely new type of humans? We know that both species hybridized, so maybe a sapiens x neanderthal?
The authors publishing this are members of school of thought not widely accepted in modern Anthropology. They argue that humans in modern East Asia are "primarily" descended from local archaic hominins, not "primarily" from humans out of Africa that admixed with archaic hominins as they migrated around the world.
This paper is specifically an argument for a "missing link" between archaic H. erectus and modern human morphologies, which pushes the emergence of these features back before Out-Of-Africa. So they avoid those terms because they're semantic distinctions the authors don't fully recognize.
I see, the old "China was first" that mix a pinch of science with a little of politics. Is an old anthropological war but Africa and Europe provided much more evidence until today If I remember correctly.
Even if they don't recognize neanderthals, is a well established taxon, and this does not differ a lot of them (in my non expert opinion), so they should show why this is enough different to deserve a second "oriental neanderthal" species. I can imagine easily neanderthals following migrating animals and conquering most of the northern hemisphere just walking from Atlantic to Pacific coasts in several generations.
>> so they should show why this is enough different t
In politics you don't need that. Just see how some political leaders avoid mentioning "sensitive" words (i.e the name of the opponent, climate change etc) for their target audience.
It's pretty clearly what used to be called "archaic Homo sapiens", which is split today into at least Neanderthals, Denisovans, and "other". The article said they ruled out Denisovan, but didn't say on what basis. Denisovan morphology is not well known; the species/subspecies is defined mainly on a genetic basis. This article only looks at morphology, so all they really can be saying is that this mandible doesn't look just like the one known Denisovan partial mandible.
I think future techniques will be able to extract DNA from things up to 1 million years old. Sure, DNA breaks down in the environment, but when you start with 60,000,000,000,000 copies of a genome in a human, I think there is a very high chance that enough fragments of that will remain to reconstruct one copy - the only hurdle is coming up with a method to do it practically.
In a hypothetical world where we could have infinite compute power and a map of the exact location of every atom in a skull, I don't think there would be any issue getting a DNA sequence.
Then we can draw the full family tree and know for sure.
This is not impossible. 2^600 is approximately 1e19. Considering there are 92 strands of DNA in a single cell, and around 37 trillion cells in a human body, a quick calculation means you need to dig up around 3000 bodies. Of course, this isn't exact (I haven't taken soft tissue decay into account, for instance), but the job is made somewhat easier by being able to piece together broken strands of DNA
That isn’t a problem at all, you will get a consensus sequence along with additional information about which variants differ in the population. That is even better info than a single perfect genome sequence.
Not impossible but there are risks in that plan. We could be in a similar problem than chatGPT is having, where part of the combinations would end being wrong and generating newer info, that would reinforce the error.
read sapiens and other books by yuval noah harari, and later there were articles that many things he claimed in his book were incorrect, or later proven to be incorrect. always blows my mind that we still just have theories of how humans spread across the world, and how the languages and culture developed. if the human development and migrations are clarified definitely, many of the regional conflicts will end.
