    Hello to the PBS Eons team, many people around the world are aware/educated on the famous American mega fauna such as the saber tooth cat and mammoths etc., but I have noticed that not many people are aware of the Australian mega fauna such as short faced kangaroos, giant wombats (Diprotodon) and of course the marsupial lion (Thylacoleo carnifex). I would love to see an episode on Australian mega fauna that might help spark interest into viewers and lead them on a path of interest just like I have been.

      Cope's life story can be summarized as a spiteful revenge mission against this guy who told him his fossil was backwards once. He discovered around 80 new species, including possibly the biggest thing to ever walk (hotly debated, mostly disregarded) all as revenge. He still didn't discover as many species nor were his discoveries as famous as that guy who told him he put his Elasmosaurus together wrong.

    @typograf62 7 років тому +241

    A small but funny detail. The dagger-like thumb of our old friend the Iguanodon was initially mounted on it's nose as a rhino horn. This is shown here in the early reconstructions. The discovery of extinct life could deserve a video in itself. The "dog tounges" that were recognised by scientist Niels Steensen as being shark teeth, fossilised and rather large from time to time. And Cuvier failing to identify some fossil bone sent to him - and admitting his failure (perhaps it was the Iguanodon? he really knew something about animal teeth).
    Btw. I once made a model of an Anatosaurus in papier mache, an old dream from boyhood come true. 1,3 meters high it still takes a lot of space in my house. Other animals also take their place. I hope to make more some day.

    • @thomasrdiehl
      @thomasrdiehl 7 років тому +24

      Yeah, this one the video didn't touch on: Early researchers thought prehistoric life was just prehistoric versions of modern life, so naturally the iguanodon was seen as a prehistoric rhino. Some went so far as to claim rhinos evolved from iguanas because nobody quite knew how evolution worked yet and the idea of evolutionary "levels" got thrown around where everything becomes a mammal if it just evolves long enough.
      Apparently, this was still taught in the Soviet Union, I vividly remember a pupil from there claiming dolphins evolved from ichthyosaurs as a fact everybody knows. Then again, the USSR did have a strange relationship to science.

    I'm 22 and for two decades I've been obsessing over these animals. It's been a trip through nostalgia seeing all of these arguments and changing opinions synthesized in a 12 minute video, and remembering that I very much lived through the whole perspective shift regarding feathered dinosaurs. People were genuinely upset at seeing feathered dinosaurs and I was overjoyed. I went to the Chicago Museum of Natural History when I was 19 and seeing Sue's skull was like meeting a childhood hero. 65 million years ago and earlier dinosaurs simply existing led to making my day to day life a little bit brighter, just knowing I share a planet with beings as incredible as they. Thanks for the vid, great trip down memory lane. And thanks to the OGs, the dinos themselves, just for existing lol.

    Doug Henderson! He's a phenomenal illustrator and one of my favorite artists today. It's also worth noting that he took many notes from 19th century romantic painters, like John Martin who did that early watercolor of iguanodon. Henderson's work is much more somber though, and very beautiful work.

    It's remarkable how much power pictures can hold. When I was young (back in the 80s, sigh) the idea of birds being dinos seemed odd, because dinos had leathery skin and birds had feathers and dinos "just didn't look like birds". Now we know many dinos had feathers and we see them depicted with them and suddenly the idea of birds being dinos seems to make so much more sense.

    Ok here's an off-the-wall wanna-know: The digestive system appears in every higher life-form on this planet. The one in the human being is fascinating and extremely complex. What do we know about its evolution?

    • @xFirebird925x
      @xFirebird925x 5 років тому +17

      A year late, but here's just what I know from some classes (probably not factoring in new research), maybe you know this already:
      Humans are part of, and evolved from, the great apes (hominidae). Great apes, like gorillas, are hindgut fermenters, meaning that they carry out fermentation by bacteria in the intestines to digest cellulose in plants. To do this (and to extract enough nutrients from plant matter to survive because plants are relatively nutritient-poor), they have longer colons. This means more guts, and a bigger belly to hold it all.
      Humans don't have bigger guts anymore, and it's likely due to 3 reasons: 1. Early "humans" started hunting and scavenging for meat, which takes less effort to extract nutrients from and is more nutrient-dense (see also expensive tissue hypothesis for the hypothesized relation to brain evolution). 2. Early "humans" started cooking with fire, and cooking can jumpstart digestion, meaning food spend less time in digestive tract. 3. Early "humans" started to walk upright, so a bigger belly is probably impractical for moving around on two legs. All of these led to the guts shrinking in humans. However, the stomach is still needed as its (very) generalized function in meat-eating animals is to process meats ("acid bath", like a much less extreme version of "destroying bodies with acid").
      The summary, in one sentence: human guts became the way they are because of cooking and possible dietary changes.
      And one last note: these are the simplified explanations born of the current scientific understanding of how humans evolved. It probably will be modified in the future when there's new findings.

      I'm not big fan of that term 'higher life form.' I don't know what criteria you place on the term, but perhaps you should reconsider its appropriateness since plants and fungi are very complex organisms. Some are extremely large----the biggest organism in the world is either a plant or a fungus depending on your preferred definitions----yet no species in either kingdom has a digestive system. Meanwhile there are some relatively simple microscopic animals which do have digestive systems.
