well it's not THAT freaky. This whole video can be summed up as "one day a giant glacier formed, and scraped a billion year's worth of dirt and rocks into the ocean, and like primordial fish food it just boosted the ocean with new and diverse life forms!" Not that crazy when you consider all those big canyons out in the western states formed by Glaciars could be made in a few million years, and sometimes in just a few thousand years! By geological standards glaciers move pretty fast!

I literally JUST got done lecturing on Proterozoic climate, and as this is my first time teaching Earth History, I'm always looking online for assistance and I couldn't have done any better than this! The complex interactions between plate tectonics, volcanism, life, the atmosphere, and climate are hard to grasp (both today and in the past) for students, so I love having multiple sources (me, my textbook, some great videos) help me to teach these topics!

I love the hypothesis that changing ocean chemistry made the larger, harder bodies of the Cambrian possible. It makes a lot of sense--the biological processes that create biomineralization would have an easier time concentrating insoluble salts from ocean water if those ions are more abundant. As ocean chemistry changes, crude and weak biomineralization processes could be gradually improved by natural selection until they are tolerant to much more scarce conditions. A really beautiful concept.

Lurkin, PBS is a great asset. Definitely worth contributing to.

I just love this show. The way it makes me look at the extraordinary past of our amazing planet, as well as the awe inspiring & vast lineage of organisms stretching billions of years behind each of us. It's so wonderful to look at the beauty of nature, learning from it instead of just exploiting it. It's an anodyne to the cynical worldview that the modern world sometimes imposes on us. An interesting aside, Sponges (as noted here) are truly amazing animals that were among the few multicellular organisms that survived "Snowball Earth" (possibly from living in the warmer waters near hydrothermal vents). There are a truly staggering 10,000 (at least) Porifera species alive, today - with many more in the fossil record. (This is actually a pretty damn big percentage of all animal life!)

No doubt Clarence Dutton was an influential man, but he was only building o-n the work of the Scottish geologist James Hutton from around 100 years before. It was Hutton who discovered "unconformities" and ushered in a new era for the science of Geology based on the presupposition of uniformitarianism. No doubt a helpful idea at the time, but a fresh appreciation of catastophism is thankfully making a mark in recent years.

@georgefspicka5483

4 жыл бұрын

As the head of volcanology for the United States Geological Survey, Dutton was probably aware of unconformities via the book “‘Principles of Geology,” which was published in 1830 by another Scottish scientist, Charles Lyell. Much of it’s content was based on the papers of James Hutton. Charles Darwin took volume 1 of the book with him on his voyage around South America.

@@joshuadeyoung5540 Maybe you're being hyperbolic, but there are a ton of reasons we know that not to be true. This was before the cambrian explosion, so the idea that during that period, life went through a similar diversification process incredibly quickly and developed intelligent life doesn't really add up. On top of that, there are plenty of marks on earth left by humans that could arguavly still be detectable after an event like this. Plastics and nuclear explosions stand out as being something that there would probably be some evidence of left over. It's conceivable that that evidence could have been lost, but just adds to the implaussibility. The lack of development of life that we see in the records immediately after this gap is the main reason that it seems impossible.

Every single time you learn things like this, the world becomes more amazing.

Thanks Eons Team! Your videos feed my sense of wonder & improve my days!

Another great video. This channel does a great job explaining geology. Seldom do I catch them giving bad/ incorrect info. In particular you're very good at distinguishing between fact and theory, as well as presenting opposing ideas. Kudos to you guys and your channel.

Best KZread channel ever! Keep it going! Thank you all.

Fantastic, thanks for showing the different hypothesis and rationale behind them. It is so much more interesting to see how researchers explore possible explanations, than to be told what the explanation is.

Thank you so much💖

Are the layers removed during the great uncomoformity in existence anywhere else? Meaning, the 1.2B years of rock layers must exist somewhere, no?

Ocean sediments I would guess. But since the oceanic crust is "recycled" relatively fast in geological terms we have no trace of those old sediments. When the oceanic crust gets pushed under the continental crust, it takes the sediments with it.

Its possible but if so they haven't been found yet and possibly never will. For instance if some or all of the missing layers could be found at the bottom of the pacific good luck excavating them.

This show is amazing. Even experts learn here. And it's so easy to understand. Amazing work

love this lady her voice is so soothing. love the way she explains. pls keep her in every videos of yours.

If both hypotheses of the Great Unconformity have their evidence, couldn't both be true? I.e. the breakup of Rodinia caused erosion to start, setting the stage for Snowball Earth, which in turn produced the grinding glaciers for some more erosion? Just because it's one gap now doesn't necessarily mean all that rock eroded in one and the same way, does it? Edit: I see SuperStormThunder had exactly the same idea a few hours ago. ;)

Depipro such a great point! In Grand Canyon the Great Unconformity is made up of several discernible unconformities exactly as you suggest!

It takes time. And scientific knowledge changes all the time as we learn more and more, and refine that knowledge. Unlike some spheres, where "knowledge" is "fixed", and has trouble dealing with it when science says differently.

Idea for a video. How did bones evolve and why did some animals use cartilage instead?

You should totally do more geology-themed episodes like this one. I really enjoyed it!

Though I had Geography subject in B.A. & am a Geography teacher too, and subscribed for National Geography magazine for two decades.Having taught about the Continental shift theory by German meteorologist Alfed Wagener .Before which the supercontinent " Pangea" existed.I have never heard of non- conformity in the strata of Grand Canyon not of 'Rodenia' for the matter of fact. Thank you for this video, was very intriguing, expands my knowledge, and illustrations are very helpful. I congratulate Pateon for this particular feature ( illustrations) because 90 % of Geography in Indian schools & colleges is taught with out it.And maybe till even the those Professors have done Ph.D also do with out it, at M.A / Ph.D level.

YES, please make more of these types of videos with more focus on geology, this was awesome!!

This is such an interesting period of time given how it shapes everything we know about life so it is always great to see coverage on recent developments over this time

Poetic ending there. Good job guys always

The timelines and models used here are outstanding, really helps get the sheer scale across. Also, kinda surprised I haven't learned about the Great Unconformity yet, although Snowball Earth is a cool as always.

A very interesting video. How about an episode exploring the history of crocodiles and how they survived the extinction of the dinosaurs.
