Neanderthal research (Introduction)

New Neanderthal research is beginning to flesh out a more complete picture of their abilities. To some anthropologists they are more advanced that previously described:- http://www.sciencedaily.com/releases/2010/09/100921171412.htm

"The fact that Neanderthals could adapt to new conditions and innovate shows they are culturally similar to us," he said. "Biologically they are also similar. I believe they were a subspecies of human but not a different species."
The powerfully built Neanderthals were first discovered in Germany's Neander Valley in 1856. Exactly who they were, how they lived and why they vanished remains unclear.
>Research shows they contributed between 1 and 4 percent of their genetic material to the people of Asia and Europe. Riel-Salvatore rejects the theory that they were exterminated by modern humans. Homo sapiens might simply have existed in larger groups and had slightly higher birthrates, he said.
>"It is likely that Neanderthals were absorbed by modern humans," he said. "My research suggests that they were a different kind of human, but humans nonetheless. We are more brothers than distant cousins."-
Another devastating blow to Evolutionary Theory. If Neanderthals are our brothers and not our progenitors, then they are forced to come up with a new 'missing link'.

Can we say pure speculation?-This is simply ridiculous.

M-B: "Another devastating blow to Evolutionary Theory. If Neanderthals are our brothers and not our progenitors, then they are forced to come up with a new 'missing link'."-I don't know how you arrive at that conclusion! There's nothing very new here. You sound as if you are desperate to find anything against evolution.-http://en.wikipedia.org/wiki/Timeline_of_human_evolution-"516 ka	Homo antecessor is the common genetic ancestor of humans and Neanderthal. At present estimate, humans have approximately 20,000...25,000 genes and share 99% of their DNA with the now extinct Neanderthal and 95-99% of their DNA with their closest living evolutionary relative, the chimpanzees. The human variant of the FOXP2 gene (linked to the control of speech) has been found to be identical in Neanderthal. It can therefore be deduced that Homo antecessor would also have had the human FOXP2 gene."

The human variant of the FOXP2 gene (linked to the control of speech) has been found to be identical in Neanderthal. It can therefore be deduced that Homo antecessor would also have had the human FOXP2 gene."-First, a note directly from the link you posted:->The classification of the great apes has been revised several times in the last few decades. Originally, Hominidae was the name given to humans and their extinct relatives, with the other great apes being placed in a separate family, the Pongidae. However, that definition makes Pongidae paraphyletic because at least one great ape species appears to be more closely related to humans than other great apes. Most taxonomists nowadays encourage monophyletic groups so this would require the use of Pongidae to be restricted to one of the great ape groups only. Thus many biologists consider Hominidae to include Pongidae as the subfamily Ponginae, or restrict the latter to the orangutans and their extinct relatives like Gigantopithecus. The taxonomy shown here follows the monophyletic groupings according to the two theories of human and great ape relationships.-
Micro-Evolution is a fact, we all know it. Macro-evolution is, in my humble opinion, at best, a delusion. I am not desperate to prove the theory wrong. It, much like the big bang theory, will prove itself wrong in time, because it, also like the big bang theory, is a case of trying to fit the data to the theory, instead of the other way round(as noted in the article above where they admittedly change the taxonomic classification of almost an entire family to fit the findings of one member of that family in order to support their claim). The evidence of evolution from one form, like the chimpanzee or great ape, into another form, like the ancestral humans, is speculative. In fact, after 15,000,000 years, chimps are still chimps, and apes are still apes, and humans, are still humans. No more proto-humans have evolved, not even a remotely similar evolutionary event has occurred. -Of course there are going to be shared genetic traits between the all species that share the same environment. We all have to breath the same chemical composition of air and the basic dietary needs of similar species are, well, similar. Similar predators that eat the same prey would logically develop somewhat similar methods for detecting and catching their quarry, though each would be limited to their own physiology. They would also be exposed to a similar range of micro-organisms, and likely have similar digestive systems to accommodate the food, and similar bacterial counts and possibly some of the same immunities. So it does not surprise me in the least that there are genetic or biological similarities. It doesn't even surprise me that there are extraordinarily genetically close species. That does not mean cats, rats, birds, algae, and humans all came from the same amoeba in the same cesspit. One argument makes logical, rational sense, the other does not. One argument has sound proof, the other does not. -As our genetic research continues, I predict that they will never find a confirmed link between humans and the ape line. (i.e. A genetic match that is close enough to be a viable breeder) They will never watch an single-celled organism spontaneously form, without prodding by men in lab coats, into an organized multi-cellular organism. The reason macro-evolution has not been witnessed is because it is not real. Darwinian evolution was a good theory, at the time it came about, because it fit the available data . However, it had the misfortune to become doctrine, and then, instead of admitting the errors in the theory, science has continuously tried to fit the data into the theory. -The reason I get so excited when I see symptoms of an old dogmatic theory crumbling as data arrives is because when the old theory finally dies, it makes room for more, new, enlightened theories to emerge from its shadow. Sorry if my excitement and enthusiasm disturb you, but I am honestly overjoyed to see some of the old placeholders getting questioned more.

He notes that a simple list of nucleotides makes the human and chimp look very similar in DNA, but complex studies show that humans and chimps are at least 15% (?) apart in DNA functional results. Can't remember his exact estimate.

I would love to read it. (Damn amazon is going to be making a mint off of me unless I can find all these at the local used bookstore). But that is part of my point. Only a few years back they were saying that we wer something like 98% similar, and now they are back tracking by 13%.. give or take. -We share features with a great many animals. We have two eyes, two ears, are warm blooded quadrapeds, with fur, and extremely similar internal organs. Those that taut macro-evolution say that it is because it has to be that way to work, and I whole heartedly agree. But that does not mean that I even remotely buy into macro-evolution. Heh, the other night on BBC they aired Stephen Hawkings 'Origin of Life: Aliens' or some such. I forget the full title.

George, -I stumbled across this list of quotes earlier while cruising around looking for a book recommended. Not taking the piss out of you or anything, but you asked me somewhere else why I get such a kick out of set backs to evolutionary theory. I think, rather than take my poor explanation, the words of other scientists are for more condemning.

I don't see how it helps your case to link to a list of quotes from a creationist website of statements against evolution. Many of them are pretty old hat. I could just as easily gather together a series of quotations from the flat-earth society that pooh-pooh the theory that the earth is round.

This is a good website for the Evolution of the Species debate. I would ask both of you to pay close attention to the number, type, and location of the fossils for each species listed here, and then look at the assumptions they make about each species based on the scant evidence. Hell, one group listed even came from two different specimens at admittedly different sediment layers and it is being put together as the same species. Again, a case of trying to make the data fit the theory.

B-M: "a case of trying to make the data fit the theory."-I would like to know what your theory is, derived from the data.-Do you think that humans have not evolved at all, and that these earlier human-like creatures as well as gorillas and chimps and orangutans have always been all separate species, or did they evolve by "microevolution" from some proto-ape or proto-human, or what?

First, a good slide show-
As I have said, evolution on a micro-scale, that is, evolution within a family, is a fact. I do not dispute that at all. I am not familiar enough with Hominoidea to say which came first/last or if they all came from each other. To use an animal that I am more familiar with, I will examine dogs. -Supposedly, all members of the Canidae family came from a common ancestor some about 40 million years ago. Now, 40 million years later, we all sorts of Canidae species. Big ones, small ones, wild ones, tame ones, but at the end of the day, they are still Canidae, not cats, or kangaroos, or rats, and as far as I am aware, all species within the family are breed-able(which is not true of humans and apes) So while I can say that to a limited extent I agree with adaptation within a species, I do not think that justifies the claim of cross species separation being reduced to a single original ancestry. I also do not think that there is enough solid evidence to make a theory about the origin of the species. Particularly in light of recent findings in genetic studies. ->It is a problematic finding because of our current understanding of early >fossils, such as the famous Toumai specimen uncovered in Chad.
>
>Toumai (Sahelanthropus tchadensis) was thought to be right at the foot of the human family tree. It dates to between 6.5 and 7.4 million years ago. In other words, it is older than the point of human-chimp divergence seen in the genetic data.
>
>"It is possible that the Toumai fossil is more recent than previously thought," said Nick Patterson, a senior research scientist and statistician at the Broad Institute of MIT and Harvard, and lead author on the Nature paper.
>
>"But if the dating is correct, the Toumai fossil would precede the human-chimp split. The fact that it has human-like features suggests that human-chimp speciation may have occurred over a long period with episodes of hybridisation between the emerging species."
>
>Commenting on the research, Daniel Lieberman, a professor of biological anthropology at Harvard, told the Associated Press: "It's a totally cool and extremely clever analysis.
>
>"My problem is imagining what it would be like to have a bipedal hominid and a chimpanzee viewing each other as appropriate mates, not to put it too crudely."

First, a good slide show-The slide show fits right in with the conclusions of :
"Not a chimp, a book I referenced yesterday, I think. Your quotes above remind me of another book, this one by Michael Denton, "Evolution: A theory in Crisis,(1986) in which he discuses analagous and homologous relationships, both in phenotype and in biochemistry of various necessary molecules, such as Hemogobin and Cyctochrome C.

Dismiss all their work? I said no such thing. There discoveries, the fossils, the advances in genetic understanding are all truly wonderful discoveries. I am simply pointing out that they need to dismiss what is tantamount to a religious ideology and take a look at the data from a fresh perspective, without Darwin's cursed theory, and let the data design the new theory, not the theory design the interpretation of the data. It is the responsibility of those scientist to be objective and they are failing miserably. Their attachment to Darwin's lovechild is as emotional and irrational as Creationism, and for the EXACT same reason, because it attempts, and ironically fails, to explain life, yet has half the calories and none of the guilt.

Here is a classic example of making the data fit the theory instead of the other way round.-Protavis-75 million years prior to Archaeopteryx.-A fully developed bird fossil 75 million years prior to their earliest ancestor. So.. did birds evolve twice, or did the chicken come before the proposed egg.

One of the other problems is that our predecessors fooled around with other branches of hominids:

The one thing that still bothers me about the whole Neanderthal thing is that if mankind has been around in some for for 40k years, and we have gone from cave dwellers to modern man in (supposedly) about 6-8k years, what did we do for the previous 32K+ years... sit around and throw rocks at each other?

We know that they were capable of complicated skill sets for a large portion of that time frame, and certainly more than the 40K that they were in Europe. I set that as a limit for myself because it was sufficient to point out the ridiculousness of the concept while still leaving room for arguments like the one you presented.-Also, we have seen 0 evidence that there has been any significant brain development, none. Not a shred. So that argument doesn't even hold water with the evidence that we do have. For as far back as we have been able to study homo sapiens and our ancestors, all we have to go on is some rather speculative concepts based on skull formation. Nothing more.

Not sure why you think I would blow a gasket over this.. It is a quite likely scenario, and in its own right, no different than what the Romans did to the Egyptians, the Europeans did to the Indians and Africans, and the Euro-Australians did to the Aborigines. One thing I would like to point out though.. The Europeans, Indians, Africans, and Aborigines are ALL HUMAN.. they all look different, have different builds, slightly different physiology, different technological levels, different cultures and linguistic skills, but they are all one species. I have no doubt in my mind that the same is true in this case. Again this to me is a case of technological and numerical superiority, not necessarily advanced evolution. (no, they are not the same.) -Hell, just compare the physiology of the modern native African versus the modern Causcasion, or Asian. If someone where to find the fossilized remains of one of each of these ethnic groups, would they classify them as 'different species' because Asians and Caucasions are typically shorter, the Asian's eye sockets are slightly different, and the Africans brow ridge and skull shape are different? -Also, I love how the dawn of humans has moved from 30k to 60k(Probably earlier as it would have taken civilization a while to mature enough to move out of Africa) now. Wish they would make up their minds....

I see some quite large gaping holes in your logic, though. -A) You are assuming that any advanced pre-stoneage civilization would &apos;evolve&apos; along the same lines that we did. i.e. They would use the same types of materials etc etc etc. While this is possibly true, it is also possibly false. Much of the materials we used today are based on petroleum, if a hypothetical civilization did exist, there are other sources of energy they could have used that would not have produced the same type of material byproducts. -B) You are using the non-existence of evidence as evidence of non-existence. -C) You are assuming that we have looked in the right places already, and that we have dug deep enough in those places to find it.-D) You are asumming that natural geological events have not eradicated the evidence(glacial migrations, volcanos, earthquakes, tectonic subduction, yada yada yada).--Anyway, I wasn&apos;t particularly leading anywhere with my comments. To me it was more of a, &quot;Well, tomorrow they will be saying something different&quot; moment.

Besides, aside from the regions of the commonly explored landmasses that we have dug up, there is still a 5.4million square mile continent that is virtually pristine when it comes to archaeological examination. You know the theory that says there is an exponential growth in technology, I think it forgot to mention the corollary to that. There is also an exponential growth in what we realize we have no clue about.

Geological evidence would offer SOMETHING to support the idea of technologically advanced civilizations--which is where I know you&apos;re going with this--Pompeii, Ashfall NE, other sites in China, India, etc. Chichen Itza and Coba were &quot;swallowed by mother nature&quot; yet the pyramids still stand; the Great Pyramid in Egypt was also once buried. There are several sites for civilization dating back to 5100 in Meso America, I&apos;ve heard some estimates as far back as 10k years. But no evidence of any kind of civilization on par with our own--they certainly never cracked the atom, or harnessed oil. &#13;&#10;> > &#13;&#10;> > If an ancient, pre stone-age civilization was that advanced, there would be solid evidence for it. &#13;&#10;> > &#13;&#10;> &#13;&#10;> &#13;&#10;> I don&apos;t necessarily disagree with you. I see some quite large gaping holes in your logic, though. &#13;&#10;> &#13;&#10;> A) You are assuming that any advanced pre-stoneage civilization would &apos;evolve&apos; along the same lines that we did. i.e. They would use the same types of materials etc etc etc. While this is possibly true, it is also possibly false. Much of the materials we used today are based on petroleum, if a hypothetical civilization did exist, there are other sources of energy they could have used that would not have produced the same type of material byproducts. &#13;&#10;> -Well, that&apos;s because clearly we were here to create Styrofoam. ;-)-> B) You are using the non-existence of evidence as evidence of non-existence. -This is only true when we take one claim in isolation. I didn&apos;t do that here.-The lack of evidence only proves our ignorance on a topic, true. But when presented with evidence that contradicts a claim made in absence of evidence, one suddenly becomes more likely. -Vimanas existed. -Vimanas are a legend.-Given that we have no evidence of Vimanas, one of these claims is a safer position. Doesn&apos;t mean its &quot;true&quot; but claims made in absence of evidence are inherently weak.-> &#13;&#10;> C) You are assuming that we have looked in the right places already, and that we have dug deep enough in those places to find it.&#13;&#10;> -I&apos;m judging research in the current state.

To me it was more of a, &quot;Well, tomorrow they will be saying something different&quot; moment. My main beef with topics like this is NOT that they change the theories and hypotheses, but that they teach the theories and hypotheses as facts. Bad juju in my opinion.-Everyone is guilty at some point about mistaking science for truth, but my experience with scientists is that they take for granted that the provisional nature of science is common knowledge.-Don&apos;t worry, I&apos;ll be discussing &quot;The Brothers Karamazov&quot; soon and will be directly arguing about an instance where a &quot;most likely explanation&quot; completely misses truth. Despite the fact that I took a very &quot;debate-oriented&quot; tact with this post, don&apos;t think that I necessarily disagree with you.

Neanderthal research about interbreeding and migration

by David Turell @, Wednesday, June 26, 2019, 19:50 (1768 days ago) @ David Turell

They covered large areas in Europe and Asia, as shown by DNA evidence of inbreeding:

https://www.newscientist.com/article/2207681-neanderthals-from-europe-may-have-ousted-t...

"The study reveals a remarkable continuity of European Neanderthal ancestry and a migration to the east which seems to have ousted their Siberian relatives. It also shows that some European Neanderthals hold clues about other ancient hominins in their DNA, as a result of interbreeding.

"Neanderthals first arose around 430,000 years ago, living in Europe and central Asia until their demise some 40,000 years ago. Few details are known about their population history, not least because the DNA in their ancient bones is hard to analyse due to degradation and contamination by microbes and from people who handled their remains.

***

"The researchers compared these DNA profiles with genetic profiles of two Neanderthals who lived in the Denisova cave in Siberia 90,000 and 120,000 years ago. They also looked at Neanderthal DNA from individuals who lived in Europe about 40,000 years ago.

“'It’s the first time we can look at Neanderthals in Europe across a long period of time,” says Peyrégne. “It’s very exciting because we don’t know about the early history of Neanderthals. We can start asking questions about the relationships of the different Neanderthals that occupied Europe. ”

"Importantly, the team managed to obtain gene sequences from DNA found in the nucleus of cells of the Neanderthal bones. This reveals far more detailed information about ancestry than DNA from mitochondria of cells, which only tells us about the maternal lineage.

"The team found that the 90,000-year-old Neanderthal from the Denisova cave was more closely related to that of 120,000-year-old European Neanderthals than to the individual who had lived in the same cave 30,000 years previously. This suggests that the European population migrated eastwards and replaced the Neanderthals already living there.

"The researchers also found that the Neanderthals living in Europe around 40,000 years ago were closely related to those who had lived there 80,000 years previously, suggesting long-term stability of this population.

“The continuity of the Neanderthal lineage in Europe suggests that Europe was the core area of Neanderthals, from which they repeatedly dispersed to the east, possibly in reaction to climatic cycles,” says Katerina Harvati at the University of Tübingen, Germany, who was not involved in this study.

"But things weren’t always so straightforward for the European Neanderthal ancestry. Peyrégne’s study also found that the mitochondrial genome of the Hohlenstein-Stadel Neanderthal was from a different lineage to that found in all other known Neanderthal genomes, as a result of breeding with a genetically distant hominin.

"This confirms an earlier genetic analysis of the Hohlenstein-Stadel Neanderthal, which proposed that this mitochondrial genome originated when Neanderthals mated more than 219,000 years ago with an early human who had migrated from Africa. However, the new analysis by Peyrégne’s team suggests an alternative origin: that this unexpected maternal lineage could be the result of interbreeding with a long-isolated Neanderthal population we have yet to detect.

“'It is possible that there was this isolated Neanderthal population that we haven’t discovered yet, that could have contributed the mitochondrial genome to the Hohlenstein-Stadel Neanderthal,” says Peyrégne.” Europe was heavily glaciated between 130,000 and 190,000 years ago and it is possible that some populations became isolated during this time, he says."

Comment: The Neanderthals made major contribution to the evolution of sapiens with all the ancient interbreeding. Following dhw's strange thinking about God and humans evolution, why did He create all these homo forms if all He wanted was humans? One finding previously presented is that Neanderthal DNA provided broader immunity. I'm sure more reasons will be found. God acts purposefully.

Usual problem: please explain why a God who specially designs whatever he wants to specially design might have found it necessary to specially design all kinds of hominins and homos before specially designing the only homo he wanted. You have admitted in the past that you have “no idea”, but perhaps you have now worked out an answer.

NB I accept the history – all these beings evolved. But even if I were to accept your fixed belief that your God’s only purpose was to create H.sapiens, I would argue (one of my logical hypotheses) that all the different hominins and homos suggest experimentation, as opposed to a God who knew exactly what he wanted and was in total control. And there is nothing “weak” or “confused” about knowing what you want and experimenting in order to get it.


DAVID (Under "Evolution"): There is great difficulty in staying with the Linnaeus classification based only only body appearance:
https://www.quantamagazine.org/phyla-and-other-flawed-taxonomic-categories-vex-biologis...

QUOTE: "Scientists can usually sidestep the problems with taxonomic rankings by separating discussions about how organisms evolved from arguments about how to name or classify them. “When you’re doing evolution, you’re doing evolution. And when you’re doing systematics and taxonomy, that’s a different thing,” he said. That separation may be awkward, but “it’s clunky because life is clunky.'”

DAVID: I still feel this is the wrong approach. Use genetic comparisons as previously proposed. God made a complex bush obviously to purposely to create the necessary econiches for a food supply to finally reach primates and then humans over 3.8 billion years. God chose the entirety of the evolutionary process of creation.

Nobody has yet found a satisfactory system of classification. As the author points out, that has nothing to do with HOW organisms evolved. Back we go again:The idea that your God designed every single life form so they could all eat or not eat one another until he designed the only thing he wanted to design is a theory for which apparently you have not yet found any support from the scientific world, and I wonder what the theological and philosophical world would make of it.

If you think that your first cause God is “weak” because he doesn’t know in advance every single detail of something that has never existed before, then so be it.

Your misleading claim that ID folks support your theory is dealt with under “Unanswered questions”.

Neanderthal research about birch tar techniques

by David Turell @, Wednesday, May 31, 2023, 04:14 (334 days ago) @ David Turell

Used as an adhesive, the Neanderthals developed an underground concentrating technique:

https://phys.org/news/2023-05-neanderthals-synthetic-material-underground-distillation....

"Researchers at the Eberhard Karls University of Tübingen and colleagues in Germany have taken a closer look at the birch tar used to affix Neanderthal tools and found a much more complex technique for creating the adhesive than previously considered.

***

"Synthetic material manufacturing remains a significant aspect of our cognitive advantage over other animals, as it requires sentient thinking, planning and comprehension of our actions to convert raw materials through a learned process.

"The Tübingen study illustrates that modern humans are not alone in this ability and were not the first to reach this mental milestone. The birch tar used by Neanderthals predates any known adaptation by modern humans by 100,000 years. The sticky material was used as an adhesive backing to connect stone to bone and wood in tools and weapons, with the added benefit of being water-resistant and resistant to organic decomposition.

***

"Through a comparative chemical analysis of two birch tar pieces from Germany and a large reference birch tar collection made with Stone Age techniques, the researchers found that Neanderthals did not simply find birch tar after a fire, nor did they use the simplest manufacturing method.

"Instead, researchers have discovered that the Neanderthals who made the German birch tar used the most efficient method with a stepwise oxygen-restricted distillation process of underground heating to extract the synthetic adhesive.

"According to the authors, "This degree of complexity is unlikely to have been invented spontaneously." Suggesting that the technique would have started with simpler methods and been developed into the more complex process by experimentation.

***

"Oxygen availability at the time of extraction left a clear marker on the experimental tars, creating a signature that clearly separated above-ground from below-ground methods. The ancient artifacts matched the below-ground manufacturing process. Both ancient tar artifacts and the below-ground experiments showed some soil mineral interaction and were free from soot-related carbons, unlike the above-ground techniques.

"Underground transformative techniques are trickier to execute than above-ground techniques because some elements cannot be observed or corrected after the procedure begins requiring a more precise set-up procedure.

"The evidence for cognitively complex Neanderthals has only increased in recent years, as archaeological evidence reveals many of the technological firsts thought to be modern human inventions were already in use among Neanderthals. At this point, it may benefit anyone who prefers thinking of human intelligence as an exceptional uniqueness to concede that Neanderthals were humans too."

Comment: more evidence that the Neanderthals were pretty bright fellows. Underground distillation is an advanced technique not suited to the sand box.

Neanderthal research about bone tools

by David Turell @, Monday, June 19, 2023, 16:12 (315 days ago) @ David Turell

Yes, they had them:

https://phys.org/news/2023-06-unseen-industry-neanderthals-bone-tools.html

"Were anatomically modern humans the only ones who knew how to turn bone into tools? A discovery by an international team at the Chez-Pinaud-Jonzac Neanderthal site settles the question. Published in PLOS ONE, it sheds light on a little known aspect of Neanderthal technology.

***

"Current studies have shown that bone tools are as numerous as flint ones. Moreover, their diversity provides evidence for a genuine industry that consists not only of retouchers but also of cutting tools, scrapers, chisels and smoothers, used for various activities and on multiple materials. These bone tools are identifiable based on traces of manufacture and use present on their surfaces as well as within the tools themselves using X-ray microtomography. Unlike examples made by modern humans that are generally shaped by scraping and abrasion, these tools were primarily made by percussion.

"The discovery of a bone industry at Chez-Pinaud-Jonzac is consistent with evidence uncovered a few years earlier by the same team at the Neanderthal site of Chagyrskaya, in the Siberian Altai. These two sites, located on either side of the Neanderthal range, testify to the fact that, like modern humans, Neanderthals made and used bone tools for their daily needs. They had the know-how to process bone using their own techniques and for their own purposes. Bone tools represent a new means for exploring and understanding Neanderthal technology."

Comment: more evidence of how smart the Neanderthals were.

Although Neanderthals live in the public imagination as hulking and slow-witted &quot;Alley Oops,&quot; Trinkaus and others say there is no reason to believe they were any less intelligent than the newly arrived &quot;modern humans.&quot; Neanderthals were stockier and had larger brows, sharper teeth and more jutting jaws, but their brain capacity appears to have been no different than that of the newcomers.-&#13;&#10;Ok.. So here we have a group that was every bit as intelligent as &apos;Humans&apos;, that have been around for an additional 400,000 years(that we know of), and interbred with modern &apos;humans&apos;. What does it sound like humans at that time were the Asians of today? Smaller physiologically, more technologically advanced, a much larger population base, and richer cultural identification? --&quot;Now, he says, researchers believe that Neanderthals &quot;were highly intelligent, able to adapt to a wide variety of ecologicalzones, and capable of developing highly functional tools to help them do so. They were quite accomplished.&quot;-&#13;&#10;oh.. and now we have gone from 60k to 100k years for the emergence of humans...sheesh-&quot;In contrast, we modern humans have only been around for 100,000 years or so and moved into colder, temperate regions only in the past 40,000 years.&quot;-&quot;Yet other stone tools were used for woodworking; among the very few wooden artifacts associated with Neanderthal sites are objects that resemble spears, plates and pegs.&quot;-Everything in that article points to Neanderthals and Homo Sapians being different tribes, not different species. It will be interesting to see what is uncovered over more time.

For instance, analysis of the Denisovan genome showed that Denisovans have contributed on the order of 5 percent of their DNA to the genomes of present-day people in Oceania, and about 0.2 percent to the genomes of Native Americans and mainland Asians. These DNA contributions not only signify interbreeding between the two groups (scientists have yet to definitively call Denisovans a separate species), but also may explain the origin of some traits of living humans. [See Photos of Denisovan Fossils and Siberian Cave]-&quot;&apos;In Tibet, an adaptation to live at high altitudes where there is little oxygen in the air has been shown to come from Denisovans,&quot; said study co-author Svante P&#228;&#228;bo, an evolutionary geneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.-&quot;Now scientists have analyzed two molars found in Denisova cave. Compared with the teeth of Neanderthals and modern humans, those Denisova teeth are very large and lack traits such as certain raised points on the crowns of molars, supporting the suggestion that Denisovans were distinct from both groups.&quot;-Comment: Separate and in Siberia. Did they come out of Africa like the rest of us?

Found not only in the Siberian cave but also in Tibet!:

"THE first fossil of our cousins the Denisovans ever to be discovered outside Siberia has been identified in Tibet. It hints that fossils from these extinct humans are more widespread than we thought, and may help settle a long-running debate about our origins.

"He and his colleagues examined a jawbone discovered in 1980 in Baishiya Karst cave, in Tibet’s Jiangla river valley. They found that the shape of the jaw and large size of the teeth are different to those of modern humans.

"Radioisotope dating suggested that the fossil is 160,000 years old at least, which is tens of thousands of years before our own species is thought to have reached the Tibetan Plateau.

"No DNA could be extracted from the fossil, but analysing collagen protein in its teeth confirmed the jawbone came from a Denisovan, because modern humans and our other extinct cousins the Neanderthals have different genes for collagen

"The finding could explain the 30,000-year-old stone tools discovered in Tibet last year. It is mind-blowing that hominins could have been living in such an extreme environment, says Hublin. “Even today, Tibet is not an easy place to live. There aren’t many resources and there’s a lack of oxygen.”

***

"Hublin says several previously discovered fossils from sites in China have features that don’t match those of modern humans or Homo erectus, another ancient hominin which is, like the Denisovans and Neanderthals, thought to have left Africa long before we did.
“I predict that most of the Chinese hominin fossil record younger than 350,000 years and older than 50,000 is made of Denisovans,” says Hublin.

“'We probably have lots of Denisovan remains sitting in museums all over the world, but they have different names on them,” says Cox.

"If Hublin is right, these fossils could help settle the debate over whether our ancestors evolved solely in Africa, or whether important steps took place in Asia too. Previous discoveries of fossils in China have been interpreted by some as intermediate species between H. erectus and modern humans, suggesting that we evolved in eastern Asia. But this idea will lose ground if the fossils turn out to be Denisovan.

"However, Sheela Athreya at Texas A&M University says that linking such fossils to Denisovans would be putting the cart before the horse. We know so little about the Denisovans’ physical characteristics and where and when they lived, she says. “We don’t know what ‘Denisovan’ is.'”

Comment: There is lots more we need to learn about this group of early homos. It must be recognized that the fossils we study are not in large enough numbers to get a clear picture of our evolution.

More fossils found in outside Siberia:

https://www.sciencenews.org/article/first-denisovan-dna-outside-siberia-found-tibetan-p...

"Denisovan mitochondrial DNA extracted from sediment layers in Baishiya Karst Cave on the Tibetan Plateau indicates that these humanlike folk inhabited the high-altitude site roughly 100,000 years ago and again around 60,000 years ago, say geoarchaeologist Dongju Zhang of Lanzhou University, China, and her colleagues. These are the first examples of Denisovan DNA found outside of Siberia’s Denisova Cave (SN: 12/16/19).

"Cave sediment possibly dating from 50,000 to 30,000 years ago also yielded Denisovan mitochondrial DNA, the scientists report in the Oct. 30 Science. If further research confirms that age estimate, it raises the likelihood that Denisovans survived on the Tibetan Plateau long enough to encounter the first humans to reach those heights as early as 40,000 years ago.

"In that case, ancient humans new to the region’s thin air may have acquired advantageous genetic traits for that environment by mating with resident Denisovans. Present-day Tibetans carry a Denisovan gene variant that aids high-altitude survival (SN: 7/2/14), although it’s not clear if interbreeding occurred on the Tibetan Plateau.

***

"In the new study, Denisovan mitochondrial DNA at Baishiya Karst Cave — found in sediment layers that also contained stone tools and pieces of animal bones — displayed close links to mitochondrial Denisovan DNA at Denisova Cave, located about 2,800 kilometers northwest of the Tibetan Plateau site. Overall, the new findings suggest “that Denisovan populations were widespread in eastern Eurasia and had adapted to the Tibetan Plateau for a long time,” Zhang says.

***

"A second study in the same issue of Science supports that idea. Nuclear DNA extracted from fossils of two ancient Asian Homo sapiens — one dating to around 34,000 years ago in Mongolia and the other to roughly 40,000 years ago in China (SN: 1/21/13) — includes segments inherited from a specific line of Denisovans, says a team led by paleogeneticist Diyendo Massilani of the Max Planck Institute for Evolutionary Anthropology in Leipzig. Those genetic segments are found in present-day mainland Asians but are distinct from Denisovan DNA that modern Papuans and Aboriginal Australians apparently inherited from ancestors who interbred with another Denisovan population, the scientists report."

Comment: These guys were all over Asia.

Denisovans are diverse

Traces of DNA pops up everywhere, but real fossils are hard to find:

https://cosmosmagazine.com/history/palaeontology/tightening-the-dragnet-on-denisovans/?...

"In a study published in Nature Ecology and Evolution, a team – led by population geneticist João Teixeira at the University of Adelaide in Australia – has attempted to nail down the identity of these enigmatic ancient humans by using AI to probe deep into the DNA of modern people of southeast Asia.

***

"Denisovans are known only from a few sparse remains, including DNA from 50,000-year-old Siberian finger bone and teeth, as well as collagen proteins from a 160,000-year-old jaw fragment in Tibet. Intriguingly, these bits of bone and teeth don’t match any of the known fossils in the human family tree.

***

"Denisovans aren’t just some curious relic of our past – we still carry significant chunks of their DNA today, which suggests they interbred with modern humans as recently as 55,000–30,000 years ago. Genetic studies reveal very little Denisovan DNA in modern Europeans and Asians (less than 0.1%), but high percentages (around 4%) in New Guinea and Australia and the Mamanwa from the Philippines, people with ancestry from the traditional hunter-gatherers of the Asia-Pacific. (For comparison, Neanderthal DNA is found in all populations outside Africa at 1–3%.) This suggests the most recent trysts between Denisovans and modern humans took place in New Guinea and Australia.

***

"To test if any of these super-archaics might be Denisovans, Teixeira and team trained an AI to use a Hidden Markov Model to “walk” along the DNA code, sniffing for two-million-year-old DNA. Thanks to the efforts of Herawati Sudoyo at the Eijkman Institute for Molecular Biology in Jakarta, who painstakingly gathered tissue samples from isolated populations ranging from tiny islands to the remote highlands of New Guinea, the AI was able to probe the genomes of 200 people from ISEA – populations that seem to have acquired their Denisovan DNA as recently as 30,000 years ago. This needle-in-a-haystack search method can detect traces of super-archaic code that represent 0.1% of the DNA – “one in a thousand ancestors”, emphasises Teixeira.

***

"The verdict?

"Inconclusive.

"A faint whiff of two-million-year-old super-archaic DNA was identified, but it wasn’t strong enough to convince the authors this was introduced by a hominin down under. It may have been a “methodological artefact”: a leftover signature from the mingling between Denisovans and a super-archaic in the northern hemisphere, possibly H. erectus – a finding which others like Cornell University’s Melissa Hubisz have reported.

"Either way, the authors agree there is no conclusive evidence for a new super-archaic signature in people of ISEA.

***
"But if this study was inconclusive, where does this leave the hunt for the Denisovans?

"The authors are somewhat divided. Most say the evidence does not support the possibility that the island pygmies or hulking H. erectus are Denisovans. One suggestion is to keep searching the little-explored caves of ISEA for the remains of Denisovans. Sulawesi is the hot favourite. It has stone tools dating back 200,000–100,000 years ago, as well the world’s oldest cave paintings.

"A convincing fossil candidate should look more archaic than modern humans but not as archaic as the island hobbits – and it should have hung around till the moderns arrived about 50,000 years ago."

Comment: Denisovans sure got around. Fossils must be in some unexplored cave waiting to be discovered.
