Cephalopods like octopus, squid, and cuttlefish seem to be as alien as any alien creature from a sci-fi movie, and it's fun to speculate that they could be aliens from another planet. But could they be aliens from right here on Earth?
Today we look at some of the strangest - and most intelligent - animals on Earth. Cephalopods.

One of the more interesting encounters of my life was having an octopus wrap a tentacle around my forearm. A friend and I were visiting the aquarium at OSU Corvallis and in a waist high tank, sat (no lap. I don't know how that works) the first living octopus I'd ever seen. She, I was told, had been a bad girl having escaped her display tank, raided every adjacent tank and eaten every living thing in them. I was invited to put my hand in the tank and cautioned not to pull away, as this could remove the mucus lining of the sucker cups on the tentacle, which could lead to an infection . She explored my arm for a bit, decided it wasn't lunchtime and let me go. It was quite a profound experience and I came away with the distinct impression of intelligence at work there. The passing years haven't shown me anything to counter that first impression. They are a marvel; with an appetite.
It ate everything else in the joint?😅
I had a brother-in-law tell me of an experience he once had dealing with an octopus. He had been attending a beach party (back in the 70's) here in the Puget Sound area (where MANY octopoda reside). Late that night, just after the LSD kicked in, a few of the folks there decided to go for a moonlight swim. Several yards off shore, my brother-in-law felt something attach itself to his chest and shoulder. He realized that a small-ish octopus had grabbed onto him. Needless to say, that completely freaked him out. Some frantic thrashing around and arm wrestling dislodged the curious critter and Dave swam back to the beach to try to gain his composure. Talk about the weirdest "buzz-kill'!
octopuses have arms, not tentacles
"Soul of an Octopus" by Sy Montgomery gives many such initial encounters, and one of the coolest tales of humans and anacondas. Oh, and in the book from which "Arrival" is taken, "Stories of Your Life" by Ted Chiang, one of the last messages the Heptapods who visit Earth give us is that we're the closest beings to them they've found.
@@rockdog2584 Nothing screams credibility like a paragraph starting with "after the LSD kicked in"
One of the most amazing things I’ve ever seen an animal do was done by an octopus that had been captured by marine biologists. It was in a tank in the cabin of the ship that was being monitored by camera. It had been there a couple of days when it obviously decided it had had enough.
It dragged itself out of the tank, off the desk, across the floor, UP THE LADDER and jumped over the side. The ladder was not visible from the octopus’s tank but the octopus did not just stumble around till it found a way out, it went directly to it. It took the shortest route out of the boat immediately. They really are amazing. It would be funny if we finally worked out how to communicate with each other with language only to find it really awkward cos we just didn’t have much in common. Just really long pauses and then, “well, anyway... it’s getting late,....so...if you’re ever in Philadelphia...”
😲😲!!

Yeah it’s something I’ve wondered about quite a bit. Particularly with pets I’ve had. I know when I think, my thoughts are automatically in English (my only language) but how do you even articulate your own thoughts to yourself without a language. When I’m hungry, those actual words come into my head “I’m hungry” but before that happens I ‘feel’ hungry. So do animals without language operate purely on feeling and emotion. I mean it seems like the obvious answer to that is yes, but I find it impossible to imagine that. Is language the only thing that makes us sentient or are all animals sentient on some level and aware that 1. They are individuals 2. They exist inside a universe. Sorry I’m not explaining myself well cos I don’t really know what I mean. I eat meat, I sometimes think we conveniently don’t think too much about this cos it would be horrific to fully understand what we’re doing for that to be part of our diet. On the other hand when people condemn the human race because it hunts whales and other animals they aren’t taking into consideration the fact that we seem to be the only species that gives a shit about the whales in the first place, apart from the whales themselves, and even then it’s just complete self interest.
Hahaha sorry. A lot of time to sit and think with this virus. And for that matter what’s the virus’s motivation. It’s only purpose is to reproduce, it’s not even technically alive. And then suddenly my brain is boggled.
Crazy frikkin universe.
@@seaoftranquility7228 It would probably be interesting for you to find out people who were born deaf either do not have an inner monologue or they monologue in sign language.
fever_unspoken. Yes, I absolutely do, that is a fascinating thought. So when you say their inner monologue is in sign, do they actually see a pair of disembodied hands in their minds eye? I mean it makes sense I guess. That’s awesome. It’s still language of course, but it totally demonstrates a different way of expressing that language, even internally. Ive been meaning to get back to this thread I just haven’t been able to think of anything new to add. And what about deaf and blind? God I’ve got an early start tomorrow and it’s getting late here in Australia, I’m gonna be thinking all night. Thanks for joining in!
@TheWeeaboo
What about that whacky scientist who was giving dolphins acid and trying to have sex with them while learning to communicate
"My Octopus teacher" is a really great movie that shows that octopuses are more than we think they are.
*documentary
@@sydn2698 It's a horror movie.
I love that film. I cried so much at the end.
That man definitely got some octopussy
"My Octopus Teacher" has totally changed the way I view human intelligence. I have a dyslexic friend who didn't finish 9th grade and yet has an innate feel for mechanics and can do complicated spatial reasoning quite easily. I feel like he draws on his body's understanding of physics for this. Maybe I'm wrong. But we have neurons in our body too... seems like muscle memory could be considered a form of intelligence....
I wonder how the other octopuses react when one has been taken by scientists and later returned to the sea? Do they have a whole history of ‘alien abduction’ stories about us?
possible. From July's Utopia: According to a study published in the journal BMC Biology, researchers have found the genes that are responsible for Human intelligence are also prevalent in Octopuses. Gene sequences called transposons. Most of these tend to be dormant, but the Long Interspersed Nuclear Elements or LINE seems to be active. These are linked with learning and memory. The researchers postulated that the secret to octopuses high intelligence is that it shares these same genes with humans. Though this may put too much faith in humans being highly intelligent.
Octopuses are mostly solitary so they probably would just try to dominate the other's territory.
I wiggled my fingers at a Cuttlefish and it copied me lol, while scuba diving in the UK :-)
That's the cutest thing I've heard this year
That's unbearable cute!
I love them! I had a similar experience.
@@SouDeePop It really should be Cuddlefish.
John Whitehouse the octopus hid from me because I found his/her hole :( I was trying to explain they are my favorite creature but he/she didn’t care. It’s ok. It was probably a female and nesting. I just left it alone.
The Octopus has always deeply intrigued me. I saw one at a zoo one time and it followed this little girl as she walked along the glass. About an hour later that same family, as well as mine, made our way back and that Octopus recognized that same little girl and followed her back and forth. We were all amazed.
Prey size? :/
@@IosafBennis never thought of that...😯
What I always thought was so interesting about octopuses is that they’re solitary creatures but they play, which is completely counterintuitive to many theories as to why play evolved. For a long time the most common theory was play evolved as a way of social conditioning.
Yes! Just exactly, precisely like bigfooti. Or is it, bigfootes?
amateur divers have observed well-fed octopuses socializing.
I mean, convergent evolution is a very common thing. Perhaps the way we developed play and the way they did had different causes but a similar looking outcome
Joe, I am amazed at your skill to deliver a ton of information in such a clear, brief, concise, and fun way. I feel like every second of your video is worth watching. Thank you.
When i was learning to swim as a kid a curious baby octopus was following me. I noticed a shadow so I put my head under water : it was legit starring at me like crazy.
Nice one
People just love to lie 😅
@@carsonclements6867 Wow, he saw an octopus in the water, what a liar. What about me, I saw a magpie today and accidentally scared it by opening my window. Such crazy stories must be made up, no way it could happen in real life. 🙄
@@carsonclements6867 he literally just said he saw a baby octopus.
Baby Octo: Hey you, kiddo, stay safe. I'm watching you.
8:52 That's actually a pretty great demonstration; really liked how simple it was and it got the point across completely
My favorite octopus story is:
An octopus (I believe he was a giant octopus) lived in an aquarium, one day he was given shrimp that had apparently gone bad. He climbed out of his tank, down a hallway, directly to the office of the employee that fed him, and THREW ONE OF THE SHRIMP AT HIM. Then he turned around and went right back to his tank.
Wow!😂
You missed the octopus dreaming, changing his pattern while doing so. That was the first time I doubted it’s strangeness and simple brain.

This is the type of stuff that has made me want to study cephalopods. The marine world is amazing and deserves more study
I've been a subscriber of yours for several years now and I can tell you that I still find your narratives and storytelling in a catagory of it's own. Unlike most others, your original and extremely intelligent thought provoking content is also often mixed with genuine humor. Thank you for your insight and hard work in bringing these to light. Having said that, I will say this, octopuses are by far one of the most inquisitive, interesting, intelligent and alien creatures on this planet.

Typical sci fi movies aren't about aliens, they're about us. Aliens are just a plot device to discuss human motivations and/or stupidity when confronted with difficulties.
Exactly Rod Serling's point in so many Twilight Zone episodes.
I guess you could infer that about anything from any film with humans in? Not only films with aliens in. I dont think its the main reason in films such as Alien
Yeah, I know. He mentioned that too.
I have to admit, these questions about extraterrestrial life certainly Octopi my thoughts.
Eh? Eh?
*slow clap that turns into roaring applause
🤔🤔🤦♀️🤦♀️😁😄😂🤣🤣🤣
**Grammar Police sirens wailing**
You caught me off guard and triggered a hearty belly laugh. Well done.
Ok that made me laugh, nice one.
They're not lying. They're just so polite and considerate that they feel changing Their form is the most accommodating thing they can do.
It'd only be lying if they'd showed up in the fake human forms first, but they didn't. So they knew how they really looked from the get go. Thermians ain't no liars
"...not the only trick they've got up their eight sleeves..." Brilliant!
Star Trek TNG S06E20 "The Chase". They explained why most of the species look alike, they all share a common ancestor in the Star Trek universe.
Wasn't that a two part episode. And besides, the real point of the episodes is that Klingons are bastards.

Really interesting. Seeing how incredibly alien cephalopods are, and how incredibly diverse life on Earth is, especially in the oceans, it's hard to imagine there could be something even more alien out there.
Octopuses, squids, cuttlefishes… whatever they’re called they’re so adorable! I love how these days people find them cute and fascinating, like they deserve. When I was a kid, my friends all thought they were gross 🐙
Star Trek has an explanation of why all of the aliens look like us. Apparently, a humanoid race spread its DNA into the beginning stages of life on multiple planets in the galaxy as a way of preserving their culture.
Ethan Hartle lol, I just commented on this.
Was this explained in the later series's. Because I dont see tos bothering to consider that. I'm not a huge trek fan so I might be wrong
@@darrenjames9891 was in TNG
Yes & no, you are describing the "Progenitors", they seeded life not as a way to preserve their DNA, but simply because the Universe was devoid of sentient life, to put it mildly......they were lonely.
@@panzermacher Honestly, that sounds like most religions' creation myths. "God was lonely, so he..."
I am so forever going to be totally pedantic and say “Octopoda”.
I say that when me and 7 friends are using the restroom.
Considering how confused and arbitrary it seems to have gotten, I will be calling them "Octo-Pussies". You know, because they have no spine.
Joe actually got this wrong. Octopoda is the taxonomic order. The proper Greek plural of octopus is octopodes. www.merriam-webster.com/words-at-play/the-many-plurals-of-octopus-octopi-octopuses-octopodes
yes!
Same.
I finished reading _Other Minds_ yesterday. Thanks for suggesting it, it was really informative and thought-provoking. ☺️
Dont forget, Voy had an entire episode about that where they encountered basically a facehugger species that used thousands of different frequencies too complex for the translator to figure out and chemical signals to control the ship. They had to recreate a cardassian scientist xenobiologist to figure out how to communicate with them. So they have done it, its just rare.
Loved this video! Such amazing creatures.
Years ago I had the chance to spend 5 days working on Bora Bora. Every morning before we had to start work I would grab my snorkel gear and go investigate the lagoon just outside of my ocean side room. There were all sorts of wonderful creatures in the coral environments just off the shore. Even a young manta ray (young, meaning it was only 6 feet across as opposed to the adults at some 15 feet from wing tip to wing tip) circling in the open areas of the deeper channels. One morning I got to watch an octopus do its thing looking for food. It let me get fairly close, about 4 feet away before it changed color, slid into a rock formation and out the other side. I followed it and saw it change colors and textures so fast I wasn't sure what I was seeing was real. It was about 4 feet long in total and moved with such ease and purpose investigating all the cracks and holes looking for food. And then it jetted away with even more speed than previously shown. I felt blessed to have been given the chance to see one in the wild and not just in an aquarium. Mind blowing creatures!
😲😲
Loved the story of the octopus who didn't appreciate the lumps of frozen shrimp pieces it was being fed. It waited until the scientist went past its tank on the way out. The scientist noticed that one arm was stretched out holding the food over the drain tube of the tank filtration and the eyes were fixed on them. Once the octopus was sure it had their attention it dropped the food into the drain showing as much contempt as it could!
I've never heard that one before, thank you for sharing.
@@KeKe-bv8qv Thanks I'm sure we underestimate their intellect!
That is seriously the best description of how color change works with the balloon & blue ink. Is that also how like iguanas & chameleons etc. Change their color?
He's not just your average Joe! The clarity in which things are described along with the sly humour........pure gold mate! Keep it up!
After an octopus solved a puzzle in a documentary before I did, I stopped eating them and started loving them.
i do both
That's when I started eating them. Either we're in charge or they are.
@Steven Gulie That's Plan B
I'm glad I never ate one. After my encounter, I swore I'd never eat them or squid.
Pigs are smart
9:53 "That's not the only trick they've got up their eight sleeves"

One thing that I love about RUclips educational videos is that they tend to be concise. A TV programme covering the same subject would have been spread out over an hour with no more information.

Your rant about how movies portray alien forms speak the same way as I see it, thank you for putting that out for the world to hear!
And - their eyes are different, they don't have blind spots like other animals.
Intelligent design of Chtulhu... awesome!
That’s because they evolve eyeballs separately from other animals. Their light sensing cells face forward and not backward like ours.
Also they can regenerate their limbs.
But their brains circle their esophaguses making it fatal for them to bite off more than they are inable to chew. These two circumstances limit the amount of caloric and nutritional value they can get from their food. Also, they are mollusks and confined to water at their current evolutionary state. And they only live a couple of years, dying soon after they mate (males) or directly after their eggs hatch (females), making the passing on of knowledge from one generation to the next impossible.
@@Markle2k So are they in a constant state of epistemological survival? Always learning how to live, without any guidance, just by watching and experimenting? Sounds a lot like me lol

I don't. Help a guy out and explain the joke?

Nice catch!
I love Galaxy Quest. My grandson watched it steadily when he was four, and I saw it multiple times, of course. I recommend it as an example of teamwork.
Maybe the in-universe reason for Aliens in Sci-fi and Humans looking so similar is because they evolved under similar pressures to us which in turn selected for similar traits through Convergent Evolution kinda like Birds and Bats. Both had similar pressures that separately selected for flight so both ended up evolving wings that aside from minor aesthetic differences are functionally identical.
The octopus-has-no-tentacles fact is something I drop on discord channels to get people mad.🤣
I remember watching a documentary where a marine biologist was being interviewed, with two cuttlefish in an aquarium behind him who were obviously very interested by this unusual activity in the lab.
Arrival is my favorite Sci-fi movie ever. Such a great concept.
13:56 - that baby photo is brilliant :)
This pisses me off too about movies. That's why I loved the depiction of the aliens in arrival so much.
I find when the Aliens in movies look completely diff from us they're used as enemies in the story. Independence day for instance, good movie.
Same here. The odds against alien life forms looking anything like us - or even like ANY Earth life - are enormous. Another thing is that they're quite unlikely to speak perfect, unaccented English. I understand why film makers do that, but I hate it anyway.
@@craigcorson3036 unlikely to speak English??? No shit!! The people in the country a few hundred miles from my country don't speak it, so a civilisation from across the galaxy aren't gonna speak it!
@@craigcorson3036 That's why Star Trek gave us the universal translator. :)
Arrival was comically bad and aliens still need to be able to form societies and be able to build ships, technology and those tentacles wouldn't make it possible now would they? You don't see dolphins or octopus building anything.
Yea, ok Joe - I'm good with "octopussy"...

From the very start of this video you've been speaking to the inner part of me that is deeply fascinated by spec bio and evo.
This video has instantly become one of my favorite videos on you tube, great work joe 👍
when i taught college english i always did a little lesson near the beginning of the semester where we talked about things NOT to do in college essays, and i told them not to start essays with "from the dawn of time" because YES THEY ALL WRITE THAT
How about, "From the start of this boring ass class..." Just kidding... BTW, I don't EVER remember starting any of my essays that way. Granted, there were quite a few I didn't start, so that might have been part of it. But still, even in my physics class, where such a cliche would be appropriate, I don't know of anyone who used that.

I figure that since they eat each other it must be part of their culture, so I'm just sayin', it's ok to eat calamari in an octopuses' garden, for me.

Just that emotions and expressions are somewhat limited...

Oh man, the rants and the tangents alone....... fantastic
Exogenesis: I want to believe.
Also if epigenisis happened twice on one planet, it basically guarantees that we are not the only planet in the universe with life.
I think NASA found fossilized bacteria on mars, but dont quote me on that. Since all it takes for life to begin is just the pure luck of a few proteins being built over the curse of a long time, life could be inevitable on many planets, but the amount of time it takes to develop information storage molecules would be a huge factor in how long it takes. Also to get any sort of complex life, life would need to develop some sort of way to get high genetic diversity in every generation like sexual reproduction.
Not necessarily. All it would guarantee is that our planet had conditions favourable to life; it wouldn't guarantee how common conditions like that are. I am still really hopeful that we find life outside of earth though.
@@amentrison2794 To be fair many of the basic components that just Earth Life needs are relatively common in the universe, so its very unlikely there isn't at least single celled organisms elsewhere in the galaxy alone.
@@KaiserMattTygore927 I absolutely agree with you which is why I'm very hopeful about finding life elsewhere. That being said, I also try to be honest about the actual evidence that currently exists.
If so, and affected by incoming 'space viruses', then even the simplest extraterrestrial life we might discover will likely have several repeating 'patterns' of development that are similar to our own.
Joe, "Epigenesis" is the development of an organism from a single cell to a baby i.e. a single zygote (a fertilized egg) begins to multiply and eventually turn into a baby; or a seed turning into a plant. I think the word you're looking for is abiogenesis, the formation of a living cell from non-living matter.
Crowbars2 I second this. Love your content and delivery Joe. Sorry to nitpick.
The joke few over both of your heads.
I think he really meant epigenesis, as in after the time when life consisted of single-celled organisms as it did for most of earth's history..
You sure the first thing you describe isn´t ontogenesis?

Best comment.
We (and most life on the planet) are born and learn thru our lifetimes. Like hot, don’t touch, dont eat this or Do eat that etc etc etc.
I believe that the octopus has a way of passing on that learned knowledge from generation to generation thru mechanisms that we just don’t understand. Just my opinion.
Alan O many animals do this, insects do for sure. Mammals don’t, they must actually be taught. But you could be right, and perhaps that’s why it can manipulate 20,000 genes? It’s actually creating a library of information for its offspring?

Epigenetics:
By the middle of the 20th century, scientists began realizing that DNA sequences weren't the only things telling genes what to do. Some instructions were also coming from the epigenome - basically a collection of other chemical markers and signals that interact with DNA and influence its activity.
Perhaps the most intriguing animal paper so far is a study published online in the winter of 2013 that appeared to show that fear memories can be inherited. Researchers from Emory University trained male mice to associate an odor with an electrical shock, so that they would get startled simply by smelling the odor by itself. Surprisingly, the scientists found that the smell also startled the next two generations of mice.

I understand the Octopus have a difficult time utilizing fire to manipulate metals.
Great vid. I love that you realize we have no idea what other life might look like. It seems that is so difficult for most to understand.

Just to be extra language-policey, I'll point out that since "octopus" is a noun, "octopi" would be an example of Latin declension, not conjugation.
Both those words apparently refer to the "number" of the subject, when I look up their definitions.

"Millions of years ago?!" But... but, that's older than the Ancient Holy Book!

One could argue that the world as they knew it was 6000 years old, not the literal earth. Same with the flood. The world as they knew it was flooded, not the entire planet.
@@solidusosiris38 Exactly. The same thing as ancient emperors saying, "I am king of kings, ruler of the entire world!" Well, as far as they knew, I guess. Many researchers think it's possible that the floods in Genesis and Gilgamesh are both based on the same ancient story referring to some huge flood (or floods) that ravaged Mesopotamia.
Funny how gods did not exist until man created them . . never content with just one, then all of a sudden he supposedly created everything, while many knew! ? ? ? certainly and beyond doubt! that the world was flat!
Another example of a commenter who has never actually studied the Church's position on pre-historic times. While some protestants do indeed believe that the universe is 6000 years old, the Catholic Church has long accepted that the universe began some 13 billion years ago.
You are on fire with this one! The introduction and the whole “octopoda” bit was amazing. Thank you nerd.
I'm going to start calling them "octopoda". It sounds a lot more correct than "octopusses", and is obviously better than "octopi"
The shout out of the movie 'Arrival' is so satisfying
4:30 don't forget, sharks were here on earth BEFORE TREES, if you look at the timelines of things like sharks, trees, dinosaurs, spiders, ants and such it's a really wild ride
6:00 blue blood actually isn't that rate tho, horseshoe crabs have blue blood, and a large part of modern medicine literally relies on that blue blood for various stuff D:
Omg, you cracked me the hell up when you said, "Smort," lol! x3
Octopuses - seems even more intelligent than many of us. “Every animal knows more than you do” Native American Proverb quotes
That's no surprise!
M. J. Golden Squirrels definitely know a lot more about finding fun little treats in the ground than I do. If you watch them,they’re NEVER unsuccessful when they stop to dig something up.However, I CAN wait till a bunch of squirrels eat all the stuff they find,promptly shoot the cute little buggers and make some stew with the vegetables that I grew which are pretty easy to find. (Not really. I just buy all that crap).
Never heard that but I always thought it.
Every you knows more than animals do.

Joe: "Arms have suction cups the whole length of the limb." Also Joe: "The nautilus can have up to 90 or more arms, but they have no suction cups on them".
tentacles are special, in that they have specialised suction cups with chitin hooks around them, on a special pad at the end of the tentacle. Neither the octopuses, nor the nautilus´arms have that. So.
I ADORE "Arrival"❤. It's bloody brilliant. I also love "Galaxy Quest" and cephalopods 🐙
I am totally fascinated by these creatures, although when you learn more about any type of animal they all become fascinating.
Fun fact: Doc Oc's arms also each have an artificial brain.
I like to think dolphins, orcas, and octopuses(sounds so weird saying it correctly), have a party once a year where they speak a common language and then go back to dominating their portion of the ocean
Hey Joe long time viewer here. But for some reason youtube the past few months hasnt been notifying me of your videos even though ive been subscribed with notifications on ever since day 1. Anyways i thought you were taking a break due to the world state, but its so good to see you and hear your voice teachong me things once again! Keep it up brother, always fascinating and love the puns/dad jokes. You are my spirit animal
Wow this was the best writing I've ever seen!
"Imagine how efficient we could be if we could convey complex ideas without having to use words". Yup screens are pretty sweet.
Or have a meme on your shirt?
Yah like body language
I’d argue that all life has an intelligence we can’t conceptualise.
all life except dogs which are braindead empty shells
I get what you mean but there are different kinds of intelligences and some are more apparent than others. You can test how smart an animal is by giving it a puzzle or maze or something that uses it's abilities the best, and see how it solves it. This is great for animals which are harder to understand like octopusses, rats etc. For ones we can more easily understand like, dolphins, elephants and the like it is easier to see their strengths and abilities. Also, some animals are just stupid and practically brain dead like Koalas.
This is not getting into things like plants which would make Octopuses seem easy to understand. That's a whole world we have a lot of work to do on.
@@6500s1 can you explain why dogs are braindead? Im not tryna be mean or nothing you just genuinely peaked my curiosity because I feel like I know why and I agree but I want to know why that is
Imagine how they would have evolved if they were able to have more than one generation of offspring and developed socially.
Jorge Morales I’m pretty sure he was joking; either that or just has some strange bias against dogs lol. But to my point: I thought you might like to know that, in the sense in which you used the word, it is spelled ‘piqued'. Honestly not tryna be a smart ass though.
I love the single frame flashes
Wow, what an incredibly well written video. I think this may be the best video you have ever done. May even be the best scripted video on RUclips. Well done.
Your best intro yet! Well done!!
Also Star Trek, Star Wars etc.: EVERY planet ALWAYS 1g, never any issues with different gravity
Spock always with his tricorder, “oxygen normal”, and they snatch their helmets off.
The gravity issue is one of the biggest reasons why I stopped believing in lunar colonization. Can you imagine daily life on the moon? It'd likely be so cumbersome as to be difficult! And evolution doesn't happen fast; by the time humans genetically adapted to lunar life, we'd have long deliberately changed ourselves.
How do you know??? How do you know it was .5-1.5g....
And the planets in star wars are all one biosphere and biome
@@coltonbates629 Planets in star wars were terraformed (i think)
You always have best videos !
I’m glad you straightened out the pluralization of octopus. I had thought it was octopi. Thanks Joe.
Dawn of time IS silly, everyone knows the good intro starts with
SINCE TIME IMMEMORIAL...
What only the few seem to know is that time clearly begins at midnight. ;)
@@annoyed707 at the midnight of time doesn't have quite the same ring to it...
by the way is 0:00hrs am or pm in that odd system some people use?
@@wilhelmhedin8845,
I believe 00:00•hrs is most likely AM ~ ^especially^ considering the way that midnight marks the ^beginning^ of the next day.
@@Ashoka_the-Great714 eggcellent
"Since 0000hrs , quite a few hours before the dawn of time, depending on time zone and DST..."
when you're right, you're right. arrival really was a great movie.
there're comments under Arrival-related videos explaining how nonsensical that movie is; Joe Scott should know better, and not recommend that movie as scientifically accurate (because it is not)
@@ireneuszpyc6684 lick your hand and slap yourself. being 100% scientifically accurate doesn't make a movie good. it's called science -fiction-, genius.
@@Asdfology there're 2 types of sci-fi: the hard one (scientifically accurate, like 2001: Space Odyssey), and the fantasy type, like "Arrival"
@@Asdfology even in this comment section some people explain why "Arrival" was silly: "..Arrival was comically bad and aliens still need to be able to form societies and be able to build ships, technology and those tentacles wouldn't make it possible now would they? You don't see dolphins or octopus building anything..."
@@ireneuszpyc6684 I'm gonna go ahead and call your "two types of scifi" nonsense... nonsense...
Just because some authors put more effort into what is *mathematically* possible vs those that prefer more embellishments to carry on with the story makes no difference in writing. Except what people want to whine about.
Take Star Trek and give it a good objective once through, and you'd realize how "science fantasy" it is. Cloaking? Force fields? Warp drives? All fantasy nonsense specifically set in place for story elements.
Arrival wasn't "silly". It was focused on a single core element of language (a thing most people don't seem to understand). That is the phenomenon where learning new languages gives you completely new perspectives.
And people are claiming tentacles can't build starships?
...
*sigh*
Any appendage that allows the use of tools and environment manipulation could build a starship given enough time and evolutionary focus.
The only point of possible contestation here is whether or not an apparently ocean based life form can develop advanced civilization without FIRE. Assuming they aren't gas balloons in a high pressure atmosphere.
I love this! Not only educational so easy to watch and listen to.
That brief shot of Tommy Wiseau when talking about the various shapes life takes on on Earth… Love the videos, Joe!
