@Question Question Well, yeah, there's that as well, but it's not the same per se. Bullet-resistant vests on today's infantrymen definitely lower the death toll significantly and are important, but the difference between wearing it and not wearing it isn't as stark as it used to be. A common soldier uses cover and doesn't rely on his armour to protect him, as it's specifically a last resort, unlike an average medieval soldier who very much did rely on that, very much incorporating it into their way of fighting. Modern tactics would be no different irregardless of if the soldiers wore armour or not, while medieval tactics had a very special role for men with heavy armour. From that perspective, tanks and armoured vehicles suit the role of plate armour a lot better.

@@eeenriquegabrielnegro8167 A helmet is a piece of protection. Same as the body armour, it's a last resort protection that cannot be relied on like a suit of armour was. It's literally the same as mentioning the protective clothing. One helmet does not change the soldier's role on the battlefield, and same goes for the shoes. You don't suddenly get the tank role because you wear them, you are still used as a basic infantryman. I'm the past, armour was a notable distinction that would put you either on the heavy infantry camp or the light infantry camp. Heavy infantry would be wearing heavy armour and holding the lines with their warm bodies and swallowing most of the damage while light infantry would be used for flanking maneuvers and supporting the lines. Today, the role of heavy infantry does not even exist, or at the very least, it's not determined by armour, because the role of damage absorbers is, again, fulfilled by tanks, not humans.

We have no fossil evidence of creatures confirmed to be giant squid relatives. There are known cephalopods from the Cretaceous that looked similar to Architeuthis, but they lived in shallow seas and appear to be more closely related to Vampyroteuthis. We thus have no evidence of how Architeuthis evolved and what their ancestors were.

We do know that there are giant squids in the deep parts of the ocean.not as large as they used to give a still larger than the squids near the surface. Hypothesis are they need to be that big to withstand the pressure of deep sea or are that big to have more volume compared to surface area so that way they can withstand the cold. But we don't really know why sea creatures in the deep get so big.

Thomas Melone. Evolution is, by definition, alteration from direct repetition of cycle. Within life (biology), such changes are called biological evolution. There are various and overlapping theories on why such change in life occurs over time. Charles Darwin offered one theory (evolution through natural selection). The ever expanding field of genetics (pioneered by Brother Mendel) offers further insights. A man called Lamarck also offered theories on how adaptive and imitative behaviors might imprint upon physiology and then be passed on and amplified over successive generations (giraffes stretch their own necks). Although long sidelined, with recent findings on neuro-physio plasticity and epigenetics, such ideas are also being increasingly considered and reseached. Simply put, the myriad of forms in the heritage of life are beyond the constraints of a single book.

@stevesteverson1730

change in allele frequency, yes.....change from one species to another no. The Cambrian explosion is direct evidence against macroevolution. What we see in the fossil record is overwhelming stasis. Which is why the absurd idea of punctuated equilibrium was put forth. DNA is inert and could never form on its on. Impossible without the help of intelligence. Not ro mention if you did have information that record, edit, and translate/copy itself you would still need a cell for it to have any function. The ultimate chicken and the egg in nature. So the reason some people reject TOE is because when you scratch the surface of the theory it is full of wholes. Very, very far from fact.

@agilemind6241

+Steve Steverson Which is why self-reinforcing chemical reactions is the current topic of research when it comes to the origin of life. There are plenty of geological processes/structures which could/can concentrate pro-biological molecules - water pockets in soil/sediment/sand, crevices in rocks, etc.. There have been a few self-catalysing chemical cycles uncovered as well - i.e. a sequence of reactions which produce more and more of all their components. Sure it's not a whole cell yet but it took a billion years over the whole planet for a cell to arise just once. So the fact that such an event hasn't been replicated in the few hundred labs over the past few decades is hardly evidence that is can't have happened. "DNA is inert and could never form on its on." I think you'll find DNA is forming on it's own in you body right now. It definitely isn't inert, in fact most people argue that DNA is too unstable for chromosome-length molecules to remain intact until cell capable of homeostasis existed. Though it is all beside the point because an RNA-world where by RNA would both be the information-storing and metabolic enzymes of the first cell-like structures is much more likely. "true" cells with DNA for information storage and proteins for metabolic enzymes would have evolved later.

Best video so far, Hank. Please give us more history about the evolution of different cephalopods - they're fascinating creatures on both ends of the spectrum (particularly with regard to their apparent intelligence and completely different abilities from vertebrates) and should be showcased far more.

Orthocones and ammonites were once very diverse in the oceans in the Paleozoic and Mesozoic Eras but by the Creatceous-Paleogene Extinction Event ammonites and orthocones went extinct although nautilus survived through the Cenozoic Era and into the present day.

I think Eons videos in general are fantastic and I watch old ones when I have free time. However this was one of your very best, partly because cephalopods are about the most interesting of all species to me. And now Nautiloids. Please do more on the amazing family here. For other topics, I would think more on making chemistry more understandable to the average person - I was 40 before I really got a clue on how chemistry makes the world, and not simply through the Haber-Bosch process.

Grym Gungus Australia split off so marsupials there had no competition whereas marsupials in other continents died off thanks to mammals.

Marsupials are mammals. You mean placental mammals.

I also would like a video on it, but in short, because they had few competition from other mammals. Australia had no mammals except marsupials and monotremates until the arrival of humans. That's why there is so much diversity of marsupials there. And south america had only marsupials, xenarthra (sloths, anteaters and armadillos) and other groups of mammals who are now extinct. Mammals like rodents, primates and felines arrived in south america relatively recently: when the Americas came together. It was also at this time that marsupials and xenarthra invaded north america. However competition and predation from the newly arrived mammals made marsupial numbers dwindle greatly (as well as other mammals native to South America, who went extinct around this time). In all other continents marsupials faced competition from other mammals, better adapted to their niches, and therefore more efficient, and that's why you don't see marsupials anywhere else, they went extinct when they faced competition from other mammals.

I'd love to hear more about the diversification of Crocodiles and Alligators. Their adaptations, their survival through millennia, it fascinates me.

Bruh, they had tons of changes and where just as diverse as their Dinosaur and Pterosaur cousins. Look at Armadillosuchus,Kaprosuchus,Metrorhychus,Nundasuchus, and other ancient crocodilmorphs.

Thank you PBS. So much content to go through during this pandemic

Awesome. Just awesome. I think at some point soon these Eons-vids will become the benchmark of educational and fun ways to introduce biology and evolution to students aged 12-17 but also to people of all ages who simply share an interest in these subjects. Quality content with much thought and work put into it.

I Hope so. Much more skilled educators on KZread than I ever had in U.S. public schools (and I went to a well funded high school, where everything was a repeat from what I learned as a little kid watching PBS and going to mueseums and reading)

Person Mcface Because 12-17 is just an estimate for the ages of kids when they begin to learn about more detailed sciences. Again, it's an estimate. There's not an exact minimum or maximum age that determines when students begin to hear about this stuff.

I'd like to see (pun intended) the evolution of eyes! How'd they start? What could they see (colors, shapes, movements, etc)? How many different kinds have there been? How many animals have them? How do they lose them? What were the most sophisticated eyes of all time? Where do human eyes fit into all this? I think we should take a "look" into this.

Richard Dawkins did some deep videos on the subject but since the far left deplatformed him it might be hard to find his stuff

Meanwhile: Gastropods chilling in the ocean floor.

In some ways than you could say the backbone evolved twice

This was probably the most intelligent animal on earth at the time. Makes you wonder if history had gone differently we'd have had squidvilization.

I had heard that It is estimate that they have the caliber to evolve like Humans. But the human evolution occured because they were forced to adapt and gain inteligence to survive. I doubt they would gain human inteligence simply because humans are gone. I still cant completely find a concrete answer to why humans gained inteligence, but most articles say it was due to competition and early humans trying to one up each other.

Come to think of it, being weak and squishy is one thing humans and cephalopods have in common. It makes sense we'd both go in for smarts. Evolution doesn't create things it doesn't need after all.

Squids and octopus are STILL very, very intellgent.

It is also worth mentioning that based on molecular evidence, it seems that the thick cuttle bone of the cuttlefish is a derived feature rather than an ancestral one, probably a way to have better boyancy control to adapt to the shallow water niche left void after the extinction of the ammonite.

These videos are so concise and clear about such complex topics.

4:50 Omanyte i choose you

I think that you should add a comment answering section like PBS Spacetime

Great video. Loved how the squids survived by living deep. Maybe another video on other survival strategies during extinction events? Why some made it though but not others?

The distant past is so mind-boggling. At one point all the animals were just scooting around slurpin' up plants, not really worried about anything but finding more food. Then one day one of them was like "No, Bob, I'm going to eat you."

I want to leave a comment, but the only thing I can think to say is WOW. Life is so complex and beautiful. Thanks to anyone and everyone who supports this channel and makes this kind of content possible. I appreciate life and its complexities and its struggles and its diversity in a way I did't before. Thank you.

Great episode! Good work. I find it fascinating that even early animal life used blood to transport nutrients etc. around the body. I would really like to see an episode on the evolutionary history of blood.

I love how passionate he is about this

I wonder if early octopuses lived in the shells of other mollusks, similar to what hermit crabs do. We've seen them carry around coconut shells like a hermit crab.

Would love to know more about the Cenozoic Era and the rise of the mammals.

I keep watching Eons videos as they come up in recommended; I never would have guessed I would find them so interesting. Great work guys.

You're a shell now, you're a squid now

THAT WAS AWESOME!!!! :-D Already loved cephalopods, and learned so much more in those 8-ish minutes than most hours-long keyword search sessions! Great stuff, and thank you!!

"your channel is super awesome!!!" - my 4 yr old Thanks !

This, with it's names and rivalries and successions, sounds like a fantasy novel like LOTR.

did I search for this? No. Do I like it? HELL YEAH!!! 🤣🥰

Love watching these as I go to sleep. I fall asleep and keep listening, my brain absorbs the knowledge, I watch more videos on squids. I wake up. I am a squid.

I want to learn more about the ancestors of modern day crocodilians!
