Are Modern Humans Really Older Than We Thought?

  • Added:  8 days ago
  • Until recently, fossil evidence for modern humans has only gone back 200,000 years. A new discovery in Morocco and thermoluminescence dating may help extend that beyond 300,000 years.

    Of course its not going to be clear cut. Evolution is very gradual.
    We will probably never find a definitive answer to this.

    Modern humans have been on this earth for more than 200000 years yets we cannot trace our history to more than 10,000 years, it is stranger than fiction

    I love it when Hank can barely contain his enthusiasm. He looked like he was about to start jumping when he was talking about how they dated the remains. That enthusiasm is contagious.

    Either that, or someone behind the camera was trying to make him lose it during filming.

    humanity is millions of years old, greater civilisations have lived and and been extinguished in the past with technologies greater then ours. just cos we have no knowledge of them does no mean they did not exist. we will be destroyed in the future and others will take our place and create greater civilisations and look back on us as primative.

  • CarthagoMike

    the really interesting thing with the older dating is that the Homo Sapiens most likely did not just live together with Neanderthalers, as previously thought, but also with other human 'species'.

  • seasong

    Listened to a talk once, where a guy researched stone tools that are 20 million years old, although the earliest humans used tools was 2 million years ago. Since his findings conflicted with the accepted evolution theory and he didn't have a degree in the field he is mostly ignored by academia ...

    If hominins were living all over Africa in varied environments and climates, why are we so hooked on the idea that they all stayed in Africa? At the least this says to me that 20,000 years is plenty of time to spread over the whole continent of Africa. But why not farther? what physical barriers would keep hominins from the levant, anatolia, and the middle east? It seems easy.

    I would like to see more of the bones than just the skull before coming to any conclusions, because to me, that skull does not look at all homo sapien; the protruding jaw, the angle of the mandible, the sloping forehead, the thick protruding brow ridge, let alone the brain case as you mentioned... looks a lot more like homo neanderthalensis or homo erectus to me

    Let's face it. At the borders of science, we tend to go for the simpler explainations of things. However when the science is finally in, it shows to be much more complex than first though. When will we stop doing this. We do it over and over and over again in every field of science. In Planetology, regarding Jupiter, there were two schools of thought, that it was smooth inside and the other that it was lumpy inside. After the JUNO mission, it was provided to be both but way more complex than anyone thought. Again and again we do this. Human habits, has a habit of not fixing it's habits.

    No, the earth and life in general are a lot younger than we think. I mean not too long ago they pulled up the femur bone of a dinosaur with a flint arrow head lodged in it as well as many different leg bones of dinosaurs found with idents from a sword found in the bone. There was no evolution nor big bang. The earth came to be just as is stated in the book of genesis.

  • confiscator
    confiscator 7 days ago

    What evidence do we use to come to the consensus that these are our direct ancestors? Are we just comparing morphology? Couldn't it be a case of convergent evolution? I'm assuming we haven't recovered DNA. I've always wondered in cases like this how we determine direct lineage. Can anyone illuminate me?

    • foobargorch
      foobargorch 1 day ago

      Yes, I think only Neanderthal DNA has been recovered, and the rest is done by morphology (cf. "anatomically modern human"), and as far as I know direct lineage is just speculation for these kinds of remains

    Key word being *anatomically* modern which is really fairly trivial. We already know that *behavioral* modernity happened relatively recently but that was the real game changer and that's still at ~50 kya. Until we find evidence of behavioral modernity significantly older than that we shouldn't consider these *anatomically* modern-like humans much different than other related hominins such as H. neanderthalensis.

      +Vercusgames you said this means we came from morroco. Literally nothing in this find gives evidence of that. In fact, because they has somewhat "advanced" tools it's probably evidence that this was just one of the many offset tribes of humans.

  • Gina Woolsey
    Gina Woolsey 8 days ago

    A large part of the reason we say anatomically modern humans evolved in East Africa is because that's largely where we find the fossils. The Great African Rift Valley has given us a lot of fossils, so we say that's where the humans must have been, even though we have no evidence to say that that's the only place they were. So yeah, a pan-African view does make a lot of sense.

      Because applied math is a recent thing. The technological advances of humans came after the establishment of science with newton. Before that things were made without mathematical thinking.

      the simple explaination is that each technological advance, speeds up forther technological advances.

    • Segkee
      Segkee 7 days ago

      Is it literal? By what measure do you deem something obvious? Did you read the Origins of the Species 100 years ago (like I did)? Or were you cool with me being over 100 years old? That fit comfortably within your understanding of how the world works. If science were limited by what lives within our reach (and not beyond it) then we would not exist in the form that we currently do. That's why I have lived so long, you understand. I feed off people like you and I attempt, when the opportunity arises, to push past the limits of what is literal, what is common, and what is sense. That much is... obvious.
