When We Met Other Human Species

Science & Technology

We all belong to the only group of hominins on the planet today. But we weren’t always alone. 100,000 years ago, Eurasia was home to other hominin species, some of which we know our ancestors met, and spent some quality time with.

    I have not heard a cohesive explanation that satisfies the break from a usual definition for species, namely when seperation and natural selection ultimately leads to pressures to conform to the environment, that will separate two similar types of biologic systems such that they can not interbreed, then that is a species. When your instruction of these findings of DNA from similar, yet distinct hominids (of the genus Homo, yes?), one must be careful not to change the definition of species to accommodate new information. The other species of the world that are subject to the same taxonomic classification will be mistreated if we, who consciously tinker with these laws of nature, are too dedicated by our story telling to make a consistent version with the existing epistemology. "Subspecies" is one of the acceptable nomenclature when two different morphological phenotype are not entirely isolated, so the gametes can still complete meiosis and joining of two sets of chromosomes is successful

    What if it’s something really simple that explains the dominance of modern hominids? What if we are kind of hyper-sexual and we just tend to reproduce faster and then we tend to take care of our children a little longer? We tend to take care of our kids well into their teen years before we release them to the wild so to speak. I mean think about it, there are about 7 billion of us and we seem to live in about every corner of the earth. What if we are genetically wired to be constantly spreading out, exploring new things, and seeking? What if we are genetically wired to want to dominate, subjugate, and control our environment which has led to our immense success in terms of our population?

    You know - with interbreeding that produces fertile offspring going on, and occupation of the same areas, it's arguable that they didn't go extinct at all. Instead, there just ceased to be a species distinction there. Picture species lineages as streams - speciation is a fork in the stream as it flows downhill/ into the future, and in this case, neither branch dries up entirely: they just meet back up again. Granted, at that point, one branch was a trickle and the other was a river, but it didn't just cease.

    I honestly don't believe that Neandertals or Denisovans have gone extinct. Just look at the different characteristics in different races - They're all "human" but not exactly similar. Jaw structure, bone structure, skull structure - each of these things varies from race to race. If anything I think that we are simply different species of human that are all being misclassified as "homosapien".

    I love how many completely unverifiable assumptions go into this video. A small, inbred family living in Siberia goes extinct, and people assume the unusual genes they had make them into a new species. Perhaps the human genome simply lost variation that uses to exist? That's like saying poodles are a separate species because they don't have certain genes in common with Great Danes. Also, the rate of divergence from other humans is probably based on the mutation rate used to determine how long ago we diverged from ape-like creatures. That itself is a massive assumption, as we can't even agree on the amount of differences we have with chimps. Older studies (and most American textbooks) claim we have 98% of genes in common. But when comparing not just specific genes but also the layout of our DNA and variations in non-coding regions, the amount of similarity goes down to a meager ~70%.

    How was interbreeding with different species? Wouldnt they be per definition be the same species?

  • failtolawl


    24 minutes ago

    There isn't really a universal definition for "species", as different 'species' of things can still produce fertile offspring. For example, simple organisms often can interbreed but are distinct enough on their to be different species, only in complex species such as mammals does it become more difficult. For the sake of presentation they made the distinction.

    "...our success as a species..." I'd say it's far too early too early to say that our species is a success... all the more so since it looks very much like we're about to exterminate ourselves, one way or another. You want to see 'successful' species? Sharks are a VERY successful species... as are crocodiles... Modern sharks have been around for about 195 million years, but their evolution actually goes back 450 million years... now THAT is successful! By comparison even crocodiles are relative new-comers... they've been around for about 200 million years. So before we go bragging about our 'success as a species', let's just remember what kind of time-scale we're working on, and not forget what the term 'successful species' actually means, eh? ;)

    Humans spread from Africa about 50,000 years ago. Neanderthals and humans diverged about 500,000 years ago. So they were closely related to us, but still separate for about 450,000 years allowing for another genetic variation that they might be considered a different species. For comparison lions and tigers diverged about 4 million years ago and can interbreed at least somewhat.

    I hate to think it but these other species of humans were probably wiped out by our ancestors. The interbreeding species part probably came from the women getting raped. Our ancestors were extremely violent. Even in more modern history there are accounts of human civilizations completely wiping out another human civilization.

    Now Human have allegedly existed for about 300 000 years , and recorded history goes back about 7 ooo years with the first advanced societies that started about 7 000 years ago. Now the fossil records show that humanities 300 000 year history is littered with hominid species that became extinct. This includes an ape like hominid with a larger brain and far greater strength then us modern humans, “that may or may not have been more intelligent than us modern humans”. Now what have people doing for 300 000 years how come all of a sudden in only the last 6000 years have humans developed technology and advanced cultures and societies .

    The question is what happened to all those hominid species that no longer exist ? Why does the fossil record have a catalogue of sudden mass animals extinctions?What would course animals to suddenly become extinct suddenly all the same time again and again ?Well maybe just maybe the world might have been just like it is now with advanced technology at some point or maybe at several times throughout humanities 300 000 year history on this world. And maybe just maybe some sort of global disaster large scale Atomic War or ecological disaster reduced that or those pasts advanced societies to almost nothing leaving just a few remains behind ( the pyramids stone henge ect ect ) Hypothesize for a moment on the outcome that a nuclear exchange between America and Russia during the cold war would have had on the world, such an event would have coursed mass animal extinctions , would have reduced the world back into the stone age leaving very little trace of the world behind.
