@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.
@stevesteverson17306 жыл бұрын
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.
@agilemind62416 жыл бұрын
+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.

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.

Yeah, I've always found this fascinating. Most animals that gain wings do so by adapting their forelimbs. But insects didn't, so they just have the wings in addition to all their legs.

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.

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.

@revolvingworld26766 жыл бұрын
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.

Great Video, Ammonites are so important for paleozoic/mesozoic stratigraphy! But, and I know you can't get every detail in your short educational videos, I have to add, that true ammonites didn't appeared until the end of the triassic period. First the Gonatites appeared from the carboniferous until the permian. From the Permian to the end of the triassic the ceratitidas dominated. They all are seperated by their complexication of their shell sutures (Goniatites - simple, ceratitidas - intermediate, ammonites - (very) complex). Not very important but neat little detail.

Ben Official This channel largely covers evolution; or at least certain evolutionary processes which species undergo to become what they are today. So I don’t see the point of your comment... Also, cephalopods losing their shell IS an evolutionary process. They can’t possibly patch the exact process that fills the gaps as, a) there are gaps in our knowledge which are gradually being filled (don’t forget that it took hundreds of millions of years of very gradual changes to get the species we recognize today) and b) this is not a biology lecture hall series; it’s a series compiled of short evolutionary explanations to get the knowledge ball rolling. It’s up to people to do their own further research if they’re so inclined. It WOULD be really cool if this channel looked into making longer, more in-depth videos on the evolution of all these species, however!

I've heard quite a bit about the origin of avian flight, but mammalian flight is something I've heard just about nothing about in terms of how it could've developed slowly. What good did skin between the fingers do to the bats' ancestors?
