DNA From Ancient Site in Spain Reshapes Human Family Tree

Six weeks ago I suggested that 2013 was already the breakthrough year for molecular anthropology, but 2013 is ending with yet another highlight. Yesterday, Nature published a stop-you-in-your tracks piece that scrambles the scientific picture of our ancient relatives.  The world-leading Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany successfully sequenced the mitochondrial genome of a 400,000 year-old ancient human from Spain. The DNA suggests the specimen was maternally related to Denisovans, rather than Neanderthals, which leaves anthropologists puzzled and may be shifting branches around in the human family tree.

The term Denisovan, distinct to both modern humans and Neanderthals, was coined just three years ago based on some limited tooth morphology, but predominantly on the distinct DNA sequenced from a 41,000 year-old toe bone found in central Asia. Since then, anthropologists have theorized that Denisovans were contemporary Asian “cousins” to Neanderthals found in Europe and the Middle East, and to modern humans who were already living throughout Africa and were venturing out of the continent for the first time 10,000 years earlier.

That was the accepted story guiding anthropologists just last month.  Now the story has changed and we are scrambling to come up with a new narrative. Is this a different species ancestral to Denisovan, but not Neanderthals? Were there two movements out of Africa before the third and final migration that Homo sapiens took in the last 50,000 years? How many different species of hominids lived in Europe, Africa and Asia in the Pleistocene? And since these beings surely interbred, can we even call them separate species? When the dust settles, a new story of human ancestry will have surely emerged. What do you think was happening back then?

    Is it still true, that if we travel far enough east we will end up in the west? Keep talking its better than fighting!

    The taxonomy of a species and its subdivisions is more an art than a science. I have spent years trying to devise phylogenetic trees based on statistical characteristics. It is not easy to do. The traditional definition of a distinct species is genetic incompatibility which limits interbreeding. Interspecies breeding usually results in infertile offspring or at least reduced fertility. This definition does not say the various “species” of hominids should be lumped in one species because we have no data of reproductive success. The appearance of an implied Denisovan mother in a Spanish child does suggest Denisovans had a wider range than previously thought but it is not shattering any scientific conclusions. The “child” (as in “descendant”, not implying “young”) could easily have migrated across Asia or his mother could have been brought west as spoils of battle or whatever. It adds to our knowledge of Denisovans but does not contradict any theories.

    To Mr. Ranganathan,

    “Special creation” should read, “abrupt mutation” (one that was found to be beneficial to subsequent offspring… The mutations that were not accidentally advantageous to the offspring would perish along with the offspring. There is no god here…!)

    Babu G. Ranganathan has managed a considerable achievement: in a feat of intellectual incompetence seldom equaled even by Kent Hovind or Walt Brown, Ranganathan has managed to get every claim in his post wrong. Not only are his claims unbacked by any evidence whatsoever, it is clear Ranganathan operates on the assumption he is not required to provide any [ipse dixit fallacy]. His only reference is to Brown, a creationist so discredited for his asinine hydroplate theory that even Answers in Genesis will not publish his “work”.
    Ranganathan even includes a fallacy of Appeal to Authority regarding Who’s Who, a document anyone may appear in by virtue of buying a membership. So not only is he being disingenuous in his claims, he is being dishonest. Dogma is not a substitute for information.
    For those inclined, I recommend the videos on YouTube “Mathematic Disproof of YEC”, “Noah’s Flood-Mathematically Impossible’ and “Repopulation of Earth by 8 Ark Survivors” by pontecanis, and the excellent series “Why People Laugh at Creationists”, also on YouTube, by Thunderf00t.

    The article ended with the following question: “What do you think was happening back then?” . I would not be surprised if there would be at least four different homonid species living at the same time ” next to each other” and might have interbred, possibly by rapings as is occuring nowadays. Of course these kind of violent occasions were relatively rare. Since agriculture was not invented, they were gartherers-hunters, probably scavengers and maybe even canibalists, and were continously moving in one direction but at a very slow pace. The article presented only the conclusions of the DNA findings and the probable age of the humanoid remains. But it should be brought in a broader context, as the making of fire, stone tools, carvings and paintings to understand the differences in development between the variations of the Homo species.

    Well, individuals genetics are affected by existence r time. The degree of affectation is part of the genetic signature. Recent migrations seem to have less of a time affect. ; )

    I believe that there are substantial factors unconsidered. The Ice Bridges for one. The AB Negative blood origin for another. I’m interested in more information on the cross continent migrations between America and Europe, say an ice bridge between Spain/France and the U.S. Possibly allowing migration both ways by foot or water craft following wild game and, or fish/marine life. One thing that will get you moving is to run out of food.

    humans aka homo sapiens OUTSIDE of AFRICA only have 1-8% Neanderthal DNA

    Based on the 92% remaining, I only pose 1 question for these commentors,

    Why is it that if we evolved on Earth we have so little adaptation to it? We are the ONLY SINLGLE species on the entire planet that has that.

    We are genetically created by a group of human looking beings , our DNA code has about 4000 splicing accidents. I guess the old testament judaic line of made us in his own image really lines up ;p

    It is pretty obvious at this point that they were subspecies, not actual species, and that they all interbred. So, there was ONE species of humans running around back then – homo sapiens, with neanderthals, sapiens, and denisovans all running around, along with homo floresiensis (which did not apparently interbreed with us) and possibly some other stragglers here and there.

    Probably, the same thing that is happening now with race.

    My theory, not being a stranger to this topic is, the diiferent speices are now what we call races (ethnicities).

    We got a lot of learning, researching, and observing to do. Not guess-timating and filling in blanks. Lets let the story unfold, without jumping to conclusions. It is human nature to try to co-relate to things, it is also human nature to jump to conclusiond, educated or not.

    This new info is amazing! :-)) All comments are very interesting too. I speculate that there were many “exoduses” out of Africa, over many millions of years. Why Africa? Because the climate around the Tropic is the most mild and stable for most life to flourish and evolve?

    I think we should learn from human behavior today, to gain some clues about what humans and human-like other animals did and why they did it thousands of years ago. Our basic behavior and perceptions haven’t changed much since prehistoric times.
    So, having this in mind, it’s hard to conceive that Homo sapiens will interbreed with other creatures that have significant differences in looks and intellectual capacity. Have these other humanoids been really so different than Homo sapiens then? Could these ancient genomes be something like genetic left-overs from down evolution lane, when Homo sapiens and these other humanoids were united in one common ancestral specie? Rather than evidence for “inter-specie” breeding. How often are those genomes found in modern human populations today?

    One things is certain thought. Fundamental changes are coming to all our paradigms about humanity and human culture, about races, ethnics, evolution and human mind. And I’m absolutely rejoicing about this all!

    NATURAL LIMITS TO EVOLUTION: Only micro-evolution, or evolution within biological “kinds,” is genetically possible (such as the varieties of dogs, cats, horses, cows, etc.), but not macro-evolution, or evolution across biological “kinds,” (such as from sea sponge to human). All real evolution in nature is simply the expression, over time, of already existing genes or variations of already existing genes. For example, we have breeds of dogs today that we didn’t have a few hundred years ago. The genes for these breeds had always existed in the dog population but never had opportunity before to be expressed. Only limited evolution or adaptation, variations of already existing genes and traits, is possible.

    The genes (chemical instructions or code) must first exist or otherwise the evolution cannot occur. Genes instruct the body to build our tissues and organs. Nature is mindless and has no ability to design and program entirely new genes for entirely new traits. Nature can only work with the genetic ability already existing in species. Nature cannot perform the genetic engineering necessary to increase that genetic ability.

    Many people have wrong ideas of how evolution is supposed to work. Physical traits and characteristics are determined and passed on by genes – not by what happens to our body parts. For example, if a woman were to lose her finger this wouldn’t affect how many fingers her baby will have. Changing the color and texture of your hair will not affect the color and texture of your children’s hair. So, even if through physical exercise an ape’s muscles and bones changed so that it could walk upright it still would not be able to pass on this trait to its offspring. Only changes or mutations for traits that occur in the genetic code of reproductive cells (i.e. sperm and egg) can be passed on to offspring. Read the author’s popular Internet article, HOW DID MY DNA MAKE ME? Apes, by the way, are quite comfortable in how they walk, just as humans are quite comfortable in how they walk. Even a slight change in the position of a muscle or bone, for either, would be excruciatingly painful and would not be an advantage for survival.

    Modern evolutionists believe and hope that over, supposedly, millions of years random genetic mutations in the genes of reproductive cells caused by environmental radiation will generate entirely new genes. This is total blind and irrational faith on the part of evolutionists. It’s much like believing that randomly changing the sequence of letters in a romance novel, over millions of years, will turn it into a book on astronomy! That’s the kind of blind faith macro-evolutionists have.

    When evolutionary scientists teach that random genetic mutations in species over, supposedly, millions of years caused by random environmental agents such as radiation, produced entirely new genes (i.e. genetic code or genetic information) leading to entirely new forms of life, they are not teaching science but simply a faith, a belief!

    What about natural selection? Natural selection doesn’t produce biological traits or variations. It can only “select” from biological variations that are possible and which have survival value. The term “natural selection” is a figure of speech. Nature doesn’t do any conscious selecting. If a variation occurs in a species (i.e. change in skin color) that helps the species survive then that survival is called being “selected.” That’s all it is. Natural selection is a passive process in nature, not a creative process.

    How could species have survived if their vital tissues, organs, reproductive systems, etc. were still evolving? A partially evolved trait or organ that is not complete and fully functioning from the start would be a liability to a species, not a survival asset. Plants and animals in the process of macro-evolution would be unfit for survival. For example, “if a leg of a reptile were to evolve (over supposedly millions of years) into a wing of a bird, it would become a bad leg long before it became a good wing” (Dr. Walt Brown, scientist and creationist). Survival of the fittest actually would have prevented evolution across biological kinds! Read my Internet article: WAR AMONG EVOLUTIONISTS! (2nd Edition).

    All species of plants and animals in the fossil record are found complete, fully-formed, and fully functional. This is powerful evidence that species did not come into existence gradually by any macro-evolutionary process but, rather, came into existence as complete and ready-to-go from the very beginning, which is possible only by special creation.

    All the fossils that have been used to support human evolution have been found to be either hoaxes, non-human, or human, but not non-human and human (i.e. Neanderthal Man was discovered later to be fully human). Textbooks and museums still continue to display examples and illustrations supporting human evolution which most evolutionists have rejected and no longer support. Many diagrams of ape-man creatures over the years were reconstructed according to evolutionary interpretations from disputable bones that have now been discredited but still being taught in school textbooks.

    What about genetic and biological similarities between species? Genetic information, like other forms of information, cannot happen by chance, so it is more logical to believe that genetic and biological similarities between all forms of life are due to a common Designer who designed similar functions for similar purposes. It doesn’t mean all forms of life are biologically related! Only within a true species can similarities be used as evidence for relationship because only within a true species can individuals be capable of mating and producing offspring.

    Also, so-called “Junk DNA” isn’t junk. Although these “non-coding” segments of DNA don’t code for proteins, they have recently been found to be vital in regulating gene expression (i.e. when, where, and how genes are expressed, so they’re not “junk”). Read my popular Internet article: HOW FORENSIC SCIENCE REFUTES ATHEISM

    The real issue is what biological variations are possible, not natural selection.

    Visit my latest Internet site: THE SCIENCE SUPPORTING CREATION .

    I discuss: Punctuated Equilibria, “Junk DNA,” genetics, mutations, natural selection, fossils, dinosaur “feathers,” the genetic and biological similarities between various species, etc., etc.

    All life began in East New York, probably on Fulton Street, roughly 125,000 years ago. People then ate with their hands, made their own weapons, had sex with whatever slowed down in front of them and used the subways to get around, not so different from today. Life is repetitive, not transformational.

    How many different species lived during the Pleistocene? Response: How many would you like to find?

    What do I think was happening back then? Response: I think pre-historical happenings become historical with every find, proving that humans are much the same – then and now.

    Common sense would indicate that all Surface Life has seen numerous stages of evolution, then it’s not so difficult to project common sense evolution to Earth itself. We take the common theory that all life began in Africa, a wonderful theory, but how many times have the collective materials that we now know as the African continent, (as with others) been Ocean Bottom? Even more interesting to me is that we’ve for so long, had a very accountable piece of history at our disposal that simply put, said, not all human life came from the very accepted Garden Of Eden. Abel’s brother was instructed to go East Of Eden to find himself a wife, “and when you see her, you will know her “. We all know that the only physical wife for a human male is a human female, not a monkey, gorilla or some other weird stretch of the mind. Would it be a great stretch of imagination, to say that human beings were on every continent of reasonable size??

    My educated guess is there was a lot of indecorous humping going on back then. Today, people might see whites and Asians as being completely differently, physically, culturally, etc. However, unless you were raised by WASPs circa 1870, nowadays, whites and Asians having relationships is not cause for concern. Similarly, I imagine Neanderthals and Denisovans and whatever other humanoidish beings lived during that time, once they got beyond the awkwardness of formally meeting one another, or dominating into submission, found it pretty easy to hump the nights away. We have always assumed that more time and study would produce new twists and links in the human evolutionary chain. What this tells us, like most anthropological studies of this nature, is that humans excel at two things: one-night stands and coming out on top. I wonder if early human precursors thought Homo sapiens were gods, which, if true, is just depressing enough to make you grateful. For what? I have no idea.

    I suspect island biology and speciation similar to the iguanas of the galapagos islands happened early in hominid evolution leading to distinct lineages. Perhaps ice separated communities, or deserts. Then a period of mixing communities again during mild weather. There were probably multiple iterations of this, leading to a really confusing family tree. Follow that by the black plague killing off anyone without some amount of immunity, and you get a bottleneck in evolution, pruning off the majority of lineages and leaving us with a relatively homogenous population in our times.

Even today, we find that there are many mtDNA lines that existed in relatively recent times and which are now just extinct.
