First let me say I’m not religious. Secondly, I am confused on how this entire evolution crap is supposed to work. Now hear me out. Saying the first humans were actually part of the ape family and eventually evolved to walk upright makes no sense to me. The reason is because virtually every bone ever found that was actually human, was human and nothing more. When “Lucy” was introduced people believed she was part ape and yet, she was just a different species of ape. Anyway, I have yet to see a single shred of evidence of evolution and don’t bother to cite the fossil record either because there are a ton of missing links. Now, lets say original humans were in fact stupid creatures who had no language and no real skills, wouldn’t it make more sense that there was no one to teach them anything? When we were babies and kids if no one taught us anything, we would be the same as the original humans. Of course when you’re the first few generations in humanity you’re going to be barbaric because you have no example. These abnormalities that has been found in some examples of original humans such as “large brains” and “abnormally shaped heads” could all be the result of birth defects, injury, lack of self care (only for the abnormally shaped head) and various other problems. We cannot assume that all had the same abnormalities. Today we still have babies born all the time with no brain, some brain, excessively large brains, smooth brains and so forth, so we need to stop assuming they were a “species” and get down to facts.
The understanding of human origins is complex and the answers are rare and fragmentary; it is a surprise to find that useful DNA has been extracted from a fossil of this age but it won't be the last surprise.
If you want to know more about this do a search for Albert Perry. His Y Chromosome is one of the most unique in the world. Scientist have traced his Y Chromosome back 336,000-340,000 years. It proves he is part Denisovan.
I think it's strange to think that the Dinesovians came from Siberia rather than migrated there. We always act like where we find the first bones identifies the origin. It's just the first ones we found.
I think given time with DNA sequencing we will get a better picture and find that the three races are different in that our common ancestors diverged by inter breeding with uncommon ancestors. So we are more like lions, tigers and cheetahs. We still retain the ability to interbreed.
Excuse me but the history that we know or think we know could fit on a head of a pin in the middle of a football stadium...
We really know nothing.. 400,000 years ago a species... how many years before that did they appear.. to get to that point, so long ago?
Did you know that the Native Americans have their own legends of giants?
"Ancient Race of White Giants Described in Native Legends From Many Tribes"
"Chief Rolling Thunder of the Comanches, a tribe from the Great Plains,
gave the following account of an ancient race of white giants in 1857:
“Innumerable moons ago, a race of white men, 10 feet high, and far more
rich and powerful than any white people now living, here inhabited a
large range of country, extending from the rising to the setting sun.
Their fortifications crowned the summits of the mountains, protecting
their populous cities situated in the intervening valleys."
Thanks for this revelation. I think it has something to do with the coming of the Carthaginians to America about 150 B.C.
When Scipio the younger surrounded Carthage about 150 B.C., the Carthaginians built 150 ships in the harbor called Birsa which was within the walls, and broke one night and disappeared. The Romans never found those ships. It is my opinion that it was those people who built the pyramids in Central America and Mexico.
office better get me because we gonna let our finds have babies llittle human science get my self control we better treat them small that's the revolutionary humans science revolves with minds eyes just like able to read out of a blue screen green hair trend
so little humans treat them well because uh it better come soon they were the new slavic
i have a dna test that all i do is wave a bannana in someone face if they start acting like a monkey or a human i continue doing this untill bannana evolved from food to sex toys. then document the results on video.
What dating technique determined a bone to be 400,000 years old? Was it the same one that dated a currently living turtle to be a million years old? Or the same one that determined 2 pcs of dna from the same sample of horse to be 2 different ages? LOL . Carbon 12 dating isnt even accurate beyond couple thousand years let alone 400k. Some of these sciences are laughable.
That is very old. Denisovans are a different line from their common ancestory with Neanderthals but the age suggests their line left Africa when Homo Erectus was common and long before Neanderthals. It also begs the question of when Neanderthal DNA entered the Denisovan line? I'm also curious to know if Denisovan DNA entered the Homo Sapiens line separately from Neanderthals or through genes already carried by Neanderthals or through both ways. Another question is how different the Denisovan line in the Altay is from these in Spain? If the interbreeding happened between all three hominids at a similar time.... how were the Denisovans able to cross with Neanderthals or humans after such a long period of seperation? It is possible that these Denisovans are just one archaic branch seperate from the Altays just as Homo Erectus is from the Sapiens branch. If anyone with any valid insight wants to comment please do. Religious trolls are wasting their time because they will just be ignored and blocked.
the only thing is missing from here other scientists input in other languages to debate the theory it is still a very narrow field still taught to those who are interested to go down the very very long ardous road of research witch may never leave to any recognition in a person life time once the pieces are put together. what we get here is partial fast food microwavable information a little brain teaser to keep us interested so we keep coming back to feed the pig in this case Google to satisfy 1% of our curiosity. if you want to dive into it your best option is still the library and books on many different languages but as unfortunate some wants to fuck with that too: Google because they are digitizing a lot of things as a person who loves to learn understand the importance of facts and real if you can change the meaning of an entire sentence by simply changing 1 word than I do not like the idea for 1 person , company to have the power and authority to take possession of something was free for centuries for humanity not just I don't trust Google intentions because I understand the power of teaching and learning.
and Still their DNA line lives on..
in a remote part of the world.. where very little breeding outside of the local populas happens..
but this DNA lives on in the Shirper people .. those who carry the genes enabling them to breathe at very high altitude...
where the rest of the worlds population can trace instead 2% of Neanderthal dna..
the shirpas have dna of the oldest human instead
the bible says that humans inter-bred with the wicked angels that assumed human form, their offspring were called the Nephilim (not to be confused with the rephaim, who lived after the deluge and were simply a race of giant humans) back to the point this kind of cross breeding would be able to cause many genetic abnormalities that would explain what the worshippers of science and evolution have yet to do
I think what scientists are finding, completely 100% coincides with the 'origins of humanity' explanations that the ancient Sumerians told in their cuneiform texts. There were many 'versions ' of man 'genetically modified' into existence by the beings who seeded human life on this planet ('gmo' being the closest word we have to explain what they did, you have to process that) All the Genesis, Old Testament , Bible stories are 'attempts' at understanding ancient, religious, historical folklore that was handed down to them and that THOSE people themselves did NOT understand in THEIR time - so like humans still do - they added shit/modified in a way that they could come to grips with on their terms - fuckin people are still doing it now/today - changing definitions of what this and that means - figure it out
Adam AND EVE STILL WORKS, THESE MORONS LIE TO YOU AND YOU SUCK IT UP, THOSE CREATURES ARE NOT HUMANS, WE MAY HAVE THERE DNA BECAUSE OF SOMEONE TRYING TO MAKE HYBRID HUMANS, LONG TIME AGO, WHO WHO KNOWS, REMEMBER ADAM NEEDED AN HELP MATE, AND GOD TOOK A RIB OF ADAM AND MADE EVE, SOUNDS TO ME HYBRID HUMAN RIGHT THERE, DNA IS FOUND IN SIDE BONES.... WE HAVE NO IDEA HOW ADAM WAS CREATED, NOR EVE, BUT THERE ARE LOTS OF HOLES IN THE MONKEY BULLSHIT,
Rizal Jose Get back to the cave you just stepped out of you flat Earth believing idiot, if the Earth is flat why does it cast a globe shadow during an eclipse ... BECAUSE ITS A GLOBE AND NOT FLAT, if it was flat the shadow would be flat, but surprise, surprise the shadow is a globe ..... work it out dummy, it means the Earth is a globe. You don't need NASA or science to tell you just try using those things on your face called eyes, even you must be able to tell the difference between a flat or globe shadow.
This info is rue but outdated now.
Latest Dna info has shown how much we owe to other ancient spieces.
Including the Neanderthals.
Hom Sapiens inherited some crotical DNA from the Neanderthals that helped them survive ine the Prehistoric European enviroment.... especially when they arrived in Europe in their "out of Africa" trek
Our Euorpean Homo Sapien ancestors apparently liked those Neanderthal women
We apparently recieved some critial immunities form them that enabled us to survive in Europe.
Compare the research and documented discoveries of LA Marzulli Catalina Island You Tube (and discoveries elsewhere) and compare them to this discovery and the 130K yr. southern California site posted today on Nature.
Does LA Marzulli give you more questions than answers?
What does the skull formation and size tell you?
Any signs of hybridization in Marzulli's research?
Do you think it is human DNA is involved somehow?
Are they human?
Would intellectually honest anthropologists, archeologists, geneticists, evolutionary biologists, astrobiologists and other scientists possibly want to know what Marzulli has discovered and why the scientific community does not either know about it or knows about it and does not address it?
Marzulli is right up front about his world view and what he believes the history of his discoveries are about.
I believe an anthropologist that has interest in native American culture would want to know what the Indians are telling Marzulli and two others doing extensive research on this subject. Historians of the America's per-Columbian history would most likely find it very interesting also.
I hope you find it interesting.
+Paul Denisovan was 12.2 to 12.5 percent "ancestral" or genetically "the Denisova–present-day human divergence is ~800,000 years", or about 2 million bases closer to a chimpanzee (in nuclear DNA).
For Neanderthal this was 12.7 percent, or 825,000 years, also about 2 million bases more "ancestral".
Of course, what they unwittingly found was evidence of hybridization.
oh dear more of the mainstream theories going down the pan ,but i expect they will still cling to the stupid idea that we all come from a common ancestor which of course is unbelievably unprovable because its not true
god...some of the racist people on here are repulsive...talking about every race but black people are aliens...or calling black people inferior... get real u sad pathetic morons its pathetic!!!.... anyhow i think it makes sense that there were many older human species all over the world and that they interbred and created todays humans.... and yh the earth is waaaaay older than scientist try and makeout.

There are many clever people commenting on this blog but nobody is comenting about the elephant in the room. Scientist(not science) stuffed up. Mainstream science dogmatically presented an idea that was wrong because of the light of new evidence. If Scientist were non dogmatic to begin with then we wouldnt be in this pickle would we.Dogmatisim is a form of faith. Faith is a religous quality. One faith has the same merit as another faith.
This specimen of Homo-Hidelbergensis is near about 400,000 years old and was found in Spain. Not Africa. The Out of Africa THEORY states that humans left Africa at a much later time and replace older hominid species. With very few specimens available, scientists made this THEORY up and has stuck to it. I personally believe that the theory is backwards. I think that modern humans developed before their proposed time period. I also believe that races developed and specialized because of their surroundings. The Negroids developed without interaction with the other hominid species. And they remain underdeveloped without mixing but still specialized and did not advance as Caucasoids and Mongoloids did. This is why the Negroid species still have more ape like skeletal features. Aboriginal Australians are similar in that aspect.
I've long suspected that the Denisovins originated somewhere further south than where they were originally discovered because they had dark hair and dark eyes. For example, even Eskimos didn't originate in Alaska.
That's why its called his-story instead of history. I believe everything we have been taught is misleading about the history of man. Thanks to ignorance, hate, envy, jealousy, etc. the burning of books with ancient knowledge and destruction of artifacts that might have had clues to this may be gone forever. PRIME example - there are exclusions of knowledge from the BIBLE (i.e. the BOOK OF ENOCH) yet THE BOOK OF ENOCH has so much knowledge about ancient history AND what's going on in the world right now, enlightening and scary - YAHWEH's coming back very soon BLESS THE HOLY CREATOR OF ALL THINGS!). But my point is if ancient Religion has been tampered with and Science can't understand what happened, why should everything else we are taught/shown be correct!?
GiggleHz you to I am a nice person and intelligent please don't speak your mind over the world wide Web because a lot of people are reading and forming an opinion what is in our heads and mind. my answer to your statement was off the shoulder on a grumpy day😊
Pat Riot some are part neanderthal...older than any black race. Some are part denisovan with admixture that give some an ability no blacks possess. Some Africans are diverse in make up while some are simply non diverse and inherited of only inbred non diverse genetics.
+It Alien World blacks don't steal his-story I could easily say everything you know is a lie 700 years ago a white man never seen north America now white are the dominant race here and if you didn't know his-story you would believe they been here for 7000
Blacks are wolves we are at the foundation of every nation we predate modern man by hundreds of thousands to millions of years. You can't steal something that was lied to you about
It's not a lie but we as humans have been corrupted. We are all brothers and sisters and with family that could be your worst enemy. Everything is not African or European it's human. Peace and love family
some so called humans fucked and get fucked by horses pigs doges in fact any thing that has a hole or remotely resembles a male phallus, so interbreeding between Hominid groups 400,000 years ago to think they didn’t is beyond naive and the species is more likely H.heidelbergensis at that age
I'm not so sure the techniques are very reliable. They seem to be putting together some sort of jigsaw puzzle on broken pieces. I'm sure they have some logical arguments but that, as the past has proved, is no guarantee that their conclusions are correct.
So what if some people use numbers for a personal agenda. That doesn't show how human DNA can't be 400,000 years old.
I'm guessing that English isn't your first language. Not a criticism or a put down but I'm having a hard time understanding what it is you're trying to say. That may be the problem, too.
+Mdebacle furthermore, the only pure-blooded humans, pure homo sapiens sapiens is black people from Africa. every other race is just a tiny little variation of their original highly compressed genome. the rest of us vary between 1- 20 per cent Neanderthal/Cro-Magnon/desovionas/ mixed breed mutts. see the blacks especially the aboriginies and Andaman islander and the elusive sentinel islanders? THOSE are the ancestors of us all and explored everywhere and invented everything we now know first. they are of the original families to venture off from the remains of the ark. just like both the north American an austraillia dinoes, they are the direct unpolluted lineage of the families and beloved pets of the ark. and that's science fact. so remember the dreamtime when the world was new and misty and dreamlike, and the rainbow serpent crossed the skies, then read the story of noah when they came out of the ark. THEN you will know where modern humans came from. what happened in pre-flood times? who knows?? but the 9 smartest people survived the cataclysm, from which we are all descended. and that's science fact as well. ask any geneticist.
+Mdebacle we are not chimps, apes, babboons or gibbons. we are not animals at all. we are different. we have no relation to any brand of chimp or apelike thing ever in history. king kong is not MY father, but is perhaps the father of many out there . My bloodline is of adams original stock, human from day 1. with inherent dominion over the animals.with inherent free will and the ability to do complex math to attempt to understand the mind of god and find his place in the cosmos. the primate like form has many variations. from like a mouse to bigfoot. saying humans are descended from ape-things (even though apes still exist and did not turn into anyone)is the same as saying an elephant is descended from a south american tapir(even though they still exist) or that the ceolocanth (which survives in its original form to this day) is what all land life came from that grew legs and walked ashore.(even though they still are the same since the beginning like everything else). however, there were many variations of each basic body plan of every species. life is a universal constant and has a basic plan and basic structures it works within the parameters of. there were a dozen different types of human before the flood, and even they came from very ancient times when we were all one breed and one language.(up till we built the 3 mile tall tower of babel dozens of thousands of years later.) and that took quite a while as well. but we were all human from day one. king kong aint MY father. (although due to primal human depravity, it wouldn't surprise me if a few sickos at some point in very ancient times went too far with their compulsions) that 4 per cent of dna makes a universe of difference.
+irishbreakfast The true test of these fossils is how "chimp-like" their DNA is. For example, Neanderthal was 15-16ths human and 1-16th ape very close to chimpanzee. This is evidence of human-ape hybridization in Genesis 6:12. As you seem to be aware, this mess was wiped out in the Great Fossilization.
Its a neanderthal, denisova was an offshoot that never encountered the Iberian peninsula. Neanderthalensis was genetically diverse far more so then human populations today, it wouldn't surprise me if this turns out to be a neanderthal who happens to more closely match denisova than other neanderoids we have previously encountered.
i find it funny that science still tries to explain stuff for our 'simple minded folks'....
everything you could imagine and want to know, they already know and use it against your spiritual evolution...
We are all hominids, and a mixture of hominids. Modern man is another type of hominid. Just making that clear because believe it or not, there are a lot of people that think everyone else were apes. LOL!! Humans mate with humans, not apes. Neandertal, Denisovan, and probably hundreds of varieties of hominids that we haven't discovered, were all human beings. Human beings come in a huge variety.
Denisovans were giants, right? Scientists are going to have to crack open the mythology books so they may know what they're looking for next. Dwarfs in Flores, check. Flores little people were mentioned in one of sinbads tales in arabian nights. I wonder if outside agencies have been manipulating human dna for a while.
Aboriginal DNA holds an ancient bloodline. One that can bake in passing out temperature and fall asleep naked in freezing conditions and wake up the next day and go about his business. Even a half caste as they were called or mulatto or what ever. Looks like a euro DNA acts like a dreamer.
If you look at the people in Africa who are thought to be the most closely related to the earliest humans, such as the San, you'll notice that they're also the most genetically diverse people in the world. So it shouldn't be a surprise that the earliest humans were even more genetically diverse than modern people like the San.
So maybe the Neanderthals, Denisovans, and all the "others" were actually all the same species whose genetic diversity was so great that based on modern genetic diversity among modern humans, we'd consider them distinct species.
I know it's probably not that simple since, for example, Subsaharan Africans have no Neanderthal DNA. But just a thought.
Raymond Nolan Scott - Don't waste your time with his type, trust me I've seen loads of them on YouTube lately and they are completely insane. They quote the King James Bible at you as proof that whites are evil and are going to be enslaved. Of course everyone brings up that King James was white so they pretend he was black to continue their delusional view of things.
Keith Roy stop ur damn lies No Neanderthal DNA is found in any Africans just Caucaisians and Asians. u also carry the RH-NEGETIVE GENE you are sub human u son of a fallen angel no more of ur white lies
But Africans have mixtures of other hominins' DNA from periods concurrent to the Neanderthal admixture, up to much more recently, which accounts for some of that genetic diversity. There were definitely several different families of hominins living alongside sapiens.
I really don't think this is all that outside of what we already understand, given that Heidelbergensis is the parent ancestor of Human, Neanderthal, and Denisovan. There clearly was interbreeding between all 4 of those species, as migrations occurred between Africa, Europe, and Asia.
Truth is, for a million years there were no nations. A tribe of people, would follow animals around the world. This whole we were here first so we blah blah blah, is dumb. Everyone took whatever land you're living on from someone else.
Exactly, that is why we have to find the Y-DNA of these Denisovans and the Spanish discovery, that is the only way we can trace these people, from father to son, plus to figure out if the two groups were able to produce offspring because if they could then they had a common ancestry, but if they couldn't they are different species altogether. These tests have to be done in order to find the absolution of these people and whether they are our cousins, ancestors or another form of living organism not of relativity to modern humans.
Nesha Davis to some extent that's correct but I feel very different from many people perhaps because I think differently I should be able to contribute that to my ancestors on both side of the family but what's makes me unique is the fact for how long down the road I was able to carry on the rhesus factor within my genetic I'm a double negative blood type and no matter how hard the so called scientists try to duplicate that we can not be cloned. some people taught have a god complex and some scientists are down right evil to the bones see Frankenstein.
yes it does , all life inc carrots and bananas and humans have a common ancestor if you go back far enough , all life descends for a common single celled life form. as for adam and eve that's just silly religious clap trap.
+HappyandAtheist that common ancestor called Adam and eve who were human... That why human DNA is not all difficult... We are all pretty much tri racial human beings... No matter how many DNA test we take its all human... We share DNA with carrots and bananas too doesn't mean we are part veggie 😊
joeschultz2 the problem here is that if these people did come from Africa it was alot fuckin earlier for 1.if you count them as modern man it kills the time line . If you don't count them as modern it kills the way we think we evolved. So either way some experts are gonna eat crow.
Yeh! whatever!...... bullshit! which way do you fuckers want it? one hand we have Lucy from Ethiopia the oldest humanoid!now we have Joe popping up from England! what 400000years haha! all lefties determining we must have a black skin eh?
Your understanding is off. Denisovans and Neanderthals are relics only 2 to 6% of their genes survive today. Truthfully Africans interbreed with these populations as well as Homo Erectus. All modern Humans have limb portions that are much more like modern Africans than ancient human populations. The ancient blood is the difference between Modern Europeans and Modern Sub Saharan Africans and the admixture continues.
There's nothing wrong with the dating on this bone except that Creationists HATE it because it contradicts their religious ideas. Faith can be a wonderful thing but it has no place interfering with scientific inquiry, which starts with a willingness to go where the evidence leads, not where preconceived religious ideas demand that you go.
+joeschultz2 Actually, There are too many assumptions in the processes used for dating. Which, isn't to say they are right or wrong. But science isn't perfect. And no matter how much you wish it or the scientists doing the tests wish it, that will never change until and if we are able to time travel and witness all events take place for ourselves. The only history we can ever be sure about, is that in which man has witnessed and recorded in some way. But even that is limited.
Now, again. I'm not saying it's right or wrong, because the theories used for some of this, are sound. In a completely natural and uncontaminated situation, they would be spot on most likely.
But as to your point about my comment on the 17k-30k range being off because of some test stating it's impossible seems a bit naive. Naive in that, it doesn't factor in everything the belief of the supernatural states.
1) God created everything over X number of "days."
2) It is also stated that a day is like X number of years to God.
3) A being who lives outside of Space and Time. A being who is all powerful and immortal isn't bound by our limitations, in which we are forced to perceive the universe. Having no beginning, for example, is completely alien to us.
4) factoring in that, if God did create the world millions of years ago, he still could have created man in the time frame I was guessing at. Which, supports, in my view, a more accurate time line based on the bible and other historical records.
All DNA based life forms on this planet share similar coding. Humans are very close to pigs (98%) & mice. Mice and humans each, for example, have about 30,000 genes, yet only 300 (99% match) are unique to either organism. Both even have genes for a tail, even though it's not "switched on" in humans. Which makes humans closer in relation to mice than chimps (96%). Explain that.
So, we believe that we evolved from ape, why? Because they kind of look like us. Then we started testing DNA and found they are pretty close to our own gene coding. Problem is, many other animals on this planet are close to us genetically. Which voids the second part of "theory" and leaves the first part nearly useless? Fossil records are also a joke in this, being as there are so many different variety of ape on this planet. To try and claim because we share a similar skull structure and similar DNA, we must be their descendants is beyond asinine. It's all assumption based theory crafting. There has never, in the history of all evolution science, been an actual change in species from a DNA based complex life form, to another species. We have only ever witnessed small changes, known as adaptation, or changes in RNA based life forms, like a virus. Yet even in a virus, it still remains a virus.
Long winded reply coming to a close. Evolution has too many holes in it to be promoted as religiously as it is. That's not to say it's wrong or right, again, I don't claim to know. Which, is all I ask of others to admit, is that they do not either, and to be honest about it, and promote it as a theory, not a fact as it is currently.
Your quote: "I'm not again't the young earth theory, but it would need to hit around the 17k to 30k mark if true." Sorry, but 30K years old is barely an improvement on 7K-10K years old. There are several substances scientists use to date fossils which decay, and all of these substances have shown fossils much older than 30K years old. They show a process which takes millions of years, in fact the genus Homo is well over a million years. If we wanted to accept your 17K-30K age of the earth theory, we would have to rewrite all the physics and geology books to do so.
Most of the creationists who are vocal are young-earthers. So unless you have some evidence that old earthers are in the majority I don't see why we should not assume the people doing the most talking aren't the majority. Regardless, your assertion that we cannot tell if an object is a thousand years old or tens of thousands of years old remains unproven, there are more than one way for such a fossil to be dated and they agree within a reasonable range. Yes,contamination is important, but they are working on and improving that as well. They can scientifically determine how elements break down and then they hone the details.
+joeschultz2 Wrong. Creationist do not believe the earth is 6,000 to 10,000 years old. There are groups who claim this, but they are not the majority, not even close.
Joseph Cowboy: Must of us believe in Intelligent design, which, is Creationism. I'm not again't the young earth theory, but it would need to hit around the 17k to 30k mark if true.
Now, here's my problem with it. If you believe in the God of the bible, then you believe in a God of laws. He created our universe under these laws. Everything functions according to them with certain exceptions. How he did it, that's up to us to uncover if we are able. From The Big Bang to whatever else.
The Big Bang Theory, is, in my view, evidence of God creating the universe. No scientist can explain it. Under every known law and using the most basic form of logic, it's easy to understand, that nothing cannot create everything (as we know it). They theorize that in a place void of energy or matter (therefore outside of time) just thought to itself one day, let's explode and magically create everything.
And I'm not joking about the "thought" part. Hawking said that the universe created itself because it had to create itself. Who likes circular logic? I know I love it.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
