A simple question. In order for studies to get funding they have to be represented on social media to draw attention to them. On social media you pay by giving information of yourself, through collecting personal data, which can be sold to institutions and companies who need to stay ahead of competition. This creates a feedback loop in which universities create free content to aggrevate usefull data which can be used for a myriad of things including student advertisements and business interests like private funding. It's a bit of a blackbox how this works especially since the data collectors don't have to be transparant about their technologies. Personally I see my data as currency because my interests will reflect on what I will be able to see on youtube. If I would watch only entertainment on this platform I would brand myself a low grade consumer and youtube would notice that by feeding me more of the same entertaining/no brainer stuff. I dont do that because I know my data is currency, it is worth something like an investment in my intelligence when I purposely look for scientific stuff, youtubr recognizes that thats the stuff you want to spend money and starts to feed me more of the same stuff.

And we think we scientists are without bias! Always present, and any new research that shows it up is worthwhile, quite apart from the other revelations about our early history.

What makes you think that chordates weren’t in the Cambrian or Precambrian. Our lineage is very old . All Bilaterians are essentially worms with bumps if they have limbs . One main lineage developed an internal support by developing a notochord (chordates) . Another main lineage developed an exoskeleton (arthropods). There are other ways of developing a support structure in a bilaterian like the hydrostatic skeleton of a starfish . That’s not evidence against evolution which is about how life diversifies

Also evolution is a fact, its one of the facts that supports the theory of evolution by natural selection. It is a scientific theory because the hypothesis is found true, and all evidence is in support of the explanation and none against it. Also common ancestory is already a demonstrated fact through genetics. You might want to upgrade your education which seems to be out of the early 1900's. Humans are apes, is a fact. Humans sharing a common ancestor with other apes is also a fact. Ah and you are a conspiracy nutter who things these scientist are "scientists" you poor dumbass.

Yes on both parts..... I remember hearing about the Ediacarian fossils back in the late 80's while working in the geo lab at a jr. college. It was shortly after they discovered them and were trying to understand the actual effects of this discovery. Looking back now, I started to think about how many great discoveries and events happened in my life that most people today view as history, Such as the discoveries in electronics or the invention of aircraft! I remember watching Armstrong taking the first steps on the moon while laying on the floor watching it on an old CRT TV while my mother was telling me to move back away from the set before it baked my eyes and brain!

Please sir I know about stromatiles. But what happend between them and coral.I grew up with "the Graval pit" in Grandville Mich right across from the digging.as kids we would pick up fossils as such normal things we used them in our game of marbles.they where individual corals.most had some kind of Crystal for the inner parts.I'm now an old and I've learned a bit.but I still have and I wonder how where the crystals formed.

I have learned from this and one or two other vids over the past couple of days that there was no ‘missing link’ in the evolution of hominids. There was a long slow and smooth transmission from early hominids leading right up to us. Having an idea that life began in the primordial soup is borne out here but this lecture fully explores the origins of life and how it progresses evolving into it’s various niches. How calcium’s were taken up by early animals both for protection and predation was fascinating amongst so many fascinating facts, if only because I easily understood it. A very entertaining, enjoyable and insightful vid. I have enjoyed it.Thank you.

Great adventure, the twin otter stuff sounds bonkers! I learned, and found fascinating, that animals would have first evolved in a low oxygen environment. Makes sense, and I also like thinking about the “arms” race of hard shells, and how different creatures pick different chemical structures to do it. Life finds LOTS of ways to make it in this realm.

With both sandstone and mudstone below that I would guess tropical swamp, river delta or really deep ocean floor transitioning to shallower warmer water since the sandstone is in such perfectly flat sheets which indicate the sandstone came from multiple layers of compressed silt and there isn't any sand in really deep water. Then there is basalt which indicates volcanic activity and then more sandstone and shale. Finally the glaciers came along and dumped all their accumulated trash. Considering all that I would guess close to the pole since that was the warmest place at that time. Just a guess of course but those animals needed warm water with lots of plankton so I think it is a reasonable guess.

Very interesting and enjoyable, always good to learn from those who have knowledge. Thank you

What a wonderful talk! Thank you!

Thank you for this :) So fascinating!

What a wonderful lesson! I particularly admire and adore the bravery and the strength of the expedition team; the report was so exciting! I am happy, that KZread recommended this feature to me (bravo in this special case for the algorithm!) and immediately subscribed to your precious channel! Greetings from Vienna, Austria!

Great lecture and insight on that time scale. I my self have a nice fossil collection with many different types of Trilobite and many Bivalve and ancient corol

I appreciate you filming this. What a wonderful lecture 😁

How can this channel have less than 5k subscribers? Great content!!

interesting lecture, I was looking for music and suddenly captured by this. There is a lot of unknowns about the early evolution of animals before the Explosion. I wonder when we can find that out.

Imagination fills in the gaps in evolution. Evolution is losing ground as a viable hypothesis. Random mutations sumple cant create complex systems. That would be a mathmatical miracle.

@@wilsontexas Or maybe you don't understand what evolution actually is. I have yet to meet any creationist who has even a very basic 5th grade understanding of evolution. My suggestion would be to search google for "berkley evolution 101" Berkley university offers a free online course that teaches the basics of evolution. its first module takes about 30 hours to complete, and after that to finish the rest of the basics curriculum is another 8-10 modules of roughly 30 hours each. After that you would have hopefully gotten just a small glimpse at the immense complexities and understanding there is known. After that you can apply to take the more advanced courses which are hundreds of hours, but usually those are not nessisary for a laymen. That gets into more specific aspects from the different branches of science that back up evolution 100% as fact.. Good luck.

sorry to interrupt your evolution church but can anyone explain how Mankind's family (chordates) are in the Geologic Record 500 million years before your religious doctrine states (even at Berkeley)? (strawman argument means you can't)

That is the fastest 86 minutes in a very long time. Absolutely fascinating and if Professor Smith had taught at school I'd have been a geologist. Beautiful presentation and narration too from the most highly qualified construction worker in the world! If you're still taking questions - How did this explosion of life in a low oxygen environment end up with an oxygen rich world? Particularly how far back could a modern human go back and still be able to live? Thank You for this series I'm off to mark the others.

Oxygen is a poison. It oxidizes a lot. Iron was abundant in precambrium oceans as free iron, it was dissolved in the water. When the first foto synthesis evolved oxygen was (stil is for plants) a byproduct that was expelled from the cell because it would damage the cell. At first, millions of years, it oxidized the free iron and that precipitated to the sea floor (now mined in Australia) and formed thick layers. At a certain point there was no more iron and the levels rose. Probably the first extinction event happened for most organisms could not handle this. The few that could evolved further. Ediacaran and Cambrium show the result. I must say that this is an oversimplication, there is far more factors involved. I do not know how far back we could go but a rough estimate would be some four hundred million years.

What a beautiful professor here

As for the apparent lack of findings in the more sandy upper shelf regions, could it just be that the environment just wasn't conducive to preservation?

I think he is saying he did not have present day access to other parts of the delta's sedimentary deposition zones. I guess as the ice melts this will change and other localities are exposed.

@@simonmasters3295 that's kind of my take as well, the continental shelf portion they are in was getting sandy layers from the upper shelf in storms, and sand isn't that conducive to preservation. But yeah, as large as the layer is maybe they will find something from the upper shelf that was more conducive like an underwater alluvial zone from a river or something with mud or silt transport into what used to be the upper continental shelf.

I found it useful the emphasis that oxygen was not a environmental driver.

Glorious!
