The SYMBIOTE (Or parasite if you're a nerd) From The Cave Explained | How Closed Evolution Works 

I found it interesting how this movie implies that these mutated monsters are the root for human beliefs in demons. That monastery had a mural depicting the mutants attacking people if i am remembering correctly. So at some point the cave parasite was able to infect people and leave the cave to hunt on the surface. Also interesting was the monastery being built over the cave entrance and the presence of dead men in armor within the cave monsters nesting area. This, as well as there being no more monsters until modern humans reentered the cave, implies that some zealous as heck holy knights not only entered the cave to confront the monsters but that they were victorious. The church was probably built to keep the parasite contained until memory of what actually happened faded. Pretty hardcore.

I don't understand the beef between different paths of microbiology, but I guess it's just a thing you understand only when you're part of that job

My Grandmother told me a story that when she was a girl she was on a cave tour. The tour guide was a bit drunk and was pointing out the Stalactites and Stalagmites and how the water dripping will make one then drip down and make the other. Someone in the tour group asked what are they called when the two come together. The guide took a moment and said a "Mighty Tight."

My favorite part of the video is when Roanoke yelled "It's Morben time!" And we watch that guy Morb all over the place

I think it's more probable that the symbiote's desire to get to the surface was triggered by it's host (humans) since it's our preferred biome. Since, as you said, all it's other hosts probably COULD get to the surface if they really tried but didn't, the symbiote may have not had any desire until it acquired a creature that actually prefers living above ground.

I always wanted to see a prequel or sequel to this film. Either a bunch of knights trying to fight these creatures off and realizing there's nothing they could do but seal the passage off Or a post apocalyptic event where survivors try to fight off these creatures hunting them day and night. Really, either one would make for a decent film.

6:50 It tickles me to no end that Roanoke is still throwing shade at Amy after all this time, got a good chuckle out of that lol

I never took the "it wants out of the cave" line to imply that it actually was a thinking thing. I always thought she meant it in a more figurative way like saying "That car just wants to go fast".

Something not enough people acknowledge in these types of creatures and their skeletons is the swollen or overly bulbous joints, often looking like severe arthritis. While the irl explanation is it makes it look more disease ridden and scarier, it could also explain the increased strength by lengthening the moment-arm at the joint. Basically allowing the muscle to pull from a higher point and increasing the leverage. Doubt you'll see this Roanoke, but it's something I've been dying to point out that no ever acknowledges in these creature flicks.

the "it wants out" line is probably more anthropomorphizing than the symbiote actually giving two shits about where it is. she wanted to get out of the cave, so her brain things she would want to leave the cave, but the "monsters" live there, it's their home, they are comfortable in the cave.

Whenever I see parasites that incorporate traits from previous hosts, it always makes me wonder: what if it accidentally takes the wrong traits?? Eg the gills of the eel, the intelligence of the rats, the sight of the humans. Whatever poor abomination crawls out of that cave will curse the evolution gods for rolling natural-1s on its evolutionary dice! 😆

I would love to see a video where you go through to explain the plot, adversaries, and monsters in the game _The Forest_ some time. Between the various cantiballs, cowmen, armsies, creepy babies, and sausage monsters, there's more than enough interesting details to get through. Plus, it would have huge interest when the sequel, _Sons of the Forest_ , drops

8:45 Humans can feel dampness and moisture through breathing, and wet environments do have a different scent than dry ones, thats probably what was implied there (I myself can tell when water is near by smelling the air, and thats probably only easier assuming saltwater)

What if the mind is not lost during infection? The reason the cave monsters might have became that way is due to isolation. The doctor at the end is just crazy because ego.

Yeah I do love when movies imply or even out right say that we'll have to learn to live with whatever monster(s) from the movie, when in reality we could easily turn its entire species into a fossil record

Dude I just realized I've been actively watching this channel for like, at least 3-4 years. Roanoke, my man, I know it may seem strange but watching your videos on marathon kept me sane through some of my darkest times, love ya my man, truthfully a shining, geeky, hella intelligent light in the darkness for me

Ah Yes, a video about a movie I vaguely remember enjoying as a child. Thank you for yet another knowledge inducing dive into nostalgia Doctor man!

0:43 If there's one thing I will never forget it's that a good number of folk tales, myths, and legends typically have some reason to exist as an explanation for something. And if the folk tale is "A bunch of guys fought monsters and sealed them away in here" then I'm gonna take that with a grain of salt and caution. You never know when the myths or legends turn out to be true, and in movies they tend to have a VERY BAD habit of being completely true or understatements.

While obviously intended to be taken as the thing is now conscious thru humans in the movie, the fact she says the thing "wanted out" doesn't necessarily mean that it was planning and conscious if looked at in a different way. Considering the thing starts morphing anatomy to the conditions of the cave, it could simply be that the woman's body is being changed, but differently, and that the conditions outside the cave are more beneficial to the symbiosis (perhaps even changing how it ended up morphing her, as the conditions involved in the cave aren't causing it to need to change as much to the bat form, possibly due to more food/warmth/light.) Her interpretations of said changes then could be, that the thing wanted the current environment, and not the old, as the changes are rewarding her (thru pleasure or thru changes in her feelings of "wants" such as maybe warmth, or drier environments, or even light.) In her current "not fully functioning right mentally" state, she could interpret the things "wanting out of the cave environment" from just what she's getting positive feedback from (avoiding cold and moist areas, low lighting, and more wanting to be around large amounts of "potential hosts" thru things like smell or sound cues.) If every time she's in different conditions that she interprets as the "cave" she's being un-rewarded with some pleasure or drive to remain there, it'd make sense that its less the parasite gaining sentience thru her, and more it just changing the hosts needs and wants to suit it and her just thinking it is taking full control (though technically i suppose it still is, just more carrot and the stick then turning into carpenters the thing). I guess that mouse seeking out cats and open areas thing would be fairly similar as a concept. The mouse's senses and thought processes are changed, but its still mostly just a mouse with an infection, not an infection in the shape of a mouse.)

What if the mutation in Jack were so aggresive cause he was actively resisting the adaptation since he felt that symbiosis was hostile rather than beneficial so the symbiosis forced adaptation on him so he prob was picking and choosing what works rather than natural flow. .But Jeane didn't have that extreme rejection so was true symbiosis at end is what I feel happened.

What if the symbiote evolves through generations of hosts, picking up certain traits and amplifying them. If they were infecting mole rats and bats before that could explain the wings and digging claws but not expressing outright sentience. But now that it's a couple generations into humans it might take on a more psychological and covert role, that might be why the first human was morphed to such an extreme degree while the chick in the end only was showing changed eyes and not claws. It might also explain the bones in the church cause they might have been ending the generational path in humans early by game ending infected comrades. If it made all those changes to survive in the cave than who's to say we arnt making it smarter, so that with its new intelligence it might decide a more covert mutation is in order to survive and propagate. Amoungus! (Just got to the end and you had the same idea. Also the reason it never left it mightve just never had the intelligence to think of leaving the cave, instead just trying to blindly survive without a thought behind it with would have ingrained survival deep in its modus operandi.)

So crazily enough the record for staying under with a rebreather is 24 hours set in 2014 but it sounds like they used multiple rebreathers to accomplish it and it didnt say anything about lithium although the article I read did say "The incredible novelty lies indeed in the decompression protocol, which introduces a new way of fathoming saturation diving by using successive gas mixes." so maybe lithium?

For the record, humans can smell water in air better than sharks can smell blood in water. Our noses can detect 1 ppb water to air.

I remember seeing this movie with my dive team! They were using the same megalodon rebreathers some of our divers used. Some of our divers had the scooters too. You could yeet those things around and just hurt yourself before those scooters were really damaged lol It was such a pain moving them around.

Some day, roanoke's gonna explain a movie to us in 2049 about a bad monster movie but with an old man voice.

20:02 A desert doesn't have to be hot. It can be cold. Mostly, it just has to receive little rainfall.

i love the little detail of recording the voiceover in an actual cave for extra immersion

These videos are quite impressive. Most movie reviews just dismiss as "absolutely impossible", but you look to and bring forward these closest -possible- explanations, and that's really cool. Keep up the good work!

I 100% thought you were about to talk about Venom, Carnage, toxin, and anti venom and the rest of the symbiotes but this was nice to watch too

You have no idea how long I’ve been waiting for this video about this movie. I remember watching this as a kid and loving it mainly because of the creatures and their unique designs which are still unique to this day and are very memorable. I have this movie on dvd so I never truly forgot about it and it’s also on Netflix right now for any of you that have not seen it.

Hey Roanoke, I dont know if you do series but could can you take a look at the stregoi from the strain? I think it is a good series for you to analyse since this is a parasite outbreak turning people into monsters aiming an oversized worm out of their mouth onto your throat.

I found this movie in a $5 creature feature dvd and my son and I love it. What I really like about movies like this and Rec is that there are scientific reasons for these demons or possessed it’s just the science is not understood. Like how there are logical suggestions for mythological creatures that weren’t understood when the myth started about.

Ahhh I remember seeing this as a kid. Lemme get my pop corn ready and watch your take on this awesome monster.

I've been wanting Roanoke to explore this movie fir so long! I love this movie and these things are super cool. Great video Roanoke!

Dude I'm so happy you did a video on this movie because I have been trying desperately to find it for literal years! I had convinced myself I was misremembering The Descent.

The more I learn about Mycology and the Fungi Kingdom the more fascinating it ALL becomes! Would love to see more videos like Superdeep where Fungi are responsible for the affects and changes to people or the environments.

This has to be my favorite Roanoke video to date. Not only because this movie has been a deep menory but also the script for it just felt like a normal discussion.

This movie is a mid-tier favorite of mine that I come back to a couple times a year. Love the aesthetic, the monster looks cool and I always enjoy Cole Hauser being a jerk who makes good points. But not once did I ever notice that they were somehow speaking normally with rebreathers in their mouths. Literally never paid attention to it, just assumed they had full masks with built-in radios. And now that I know, I can never un-know it. Thank you, Roanoke.

Thanks so much Roanoke! I've been asking you to cover this for quite some time so thank you for finally doing it!

This was one of my favorite monster movies when I was younger, thank you Roanoke for giving such an awesome video to enjoy.

One of my fave movies. Good script on this one. Got a few giggles and some insight out of it. Bravo Roanoke. I like how you're bypassing copywrite nowadays. Keep up the great work.

I never knew Charlie's Angels: Full Throttle was actually a horror movie. You learn something new every day.

One of my favorite videos you have done. I’ve watched all since I found you a couple weeks ago. Great work. Thank you.

Thanks for continuing to cover these types of films loving your commentary and scientific approach! I will say I think The light touch of ambient music is much more enjoyable compared to the echoing effect

I love this movie for a number of reasons... mostly how reckless all the teams in this film are. It is hilariously terrifying. Somewhat wanted a sequel.

Whenever you're able to, I'd love to see a video on nope. I found the whole plot twist with the ufo really interesting

I knew you'd eventually review this movie, the concept of the creatures always interested me as a kid and I've always wondered if they would still take that same form on the surface.

This channel is the best. Legit science of the best kind, good movie recaps, and humor! You can’t go wrong here

I always find these kinds of body change/deevolution movies terrifying. Definitely a phobia of mine.

I JUST WATCHED THIS MOVIE!! Me and one of my few friends also tentatively interested in horror decided to get together and we perused Netflix to try and find something but we were just confused this whole movie. Not by the creatures, but by the characters' actions. We liked the end though. I'm so glad you're covering it! I'm sending this to her for sure!!! :D

Always look forward to these I tend to get anxious at night and can't sleep and have these videos playing through the night thank you Roanoke!

This one made me laugh so hard i cried. Thank you for always having funny stuff in your videos, i rewatch my favs when I'm feeling down.

Hey Roanoke, you should look at the aliens from the X-Com video game series and how they were improved with human genes.

I was wondering if you ever thought about doing a break down in the divergent evolution/morphology of the Eloi and the Morlocks from HG Wells' "The Time Machine". I always felt that was a really interesting plot point, and wondered if they were two different species at that point, or if they were just differently adapted/socially integrated beings of the same species.

This is the one that brought me to this channel and it's basically been on repeat ever since

Wow, I discovered you channel last week and went looking for a video on this movie, now its here!

CO2 scrubbers are apparently highly dependant on workload and temp and may last on their own for 1-10 hours. Maybe pair that with a pure O2 tank slowly giving off O2 in the right amountz and under ideal conditions you might end up with 24 hours

This movie plot reminds me so much of Greig Beck’s Journey to the Centre of the Earth series- those books are wild (I love them). Also- I just discovered this channel and I’ve been binge watching everything because it’s so amazing!!! 👏👏👏

Interesting bringing up the whole "Snap on" of consciousness. I remember around 3 my first memory and memorably functional use of my brainmeat was going to the circus with my mother and father. The first and last time I saw them happy together. Hell of a memory to start with. I've never had someone describe that "Snap" effect quite so well, good work Roanoke. (GA represent)

The wildest thing about this channel is everytime my brain recalls a movie I watched when I was a kid he releases a video on it the next week GET OUT OF MY HEAD

34:58 Mine was waking up screaming from a night terror. Yes, that's my first ever actual memory, my first conscious memory is one of absolute terror about something haunting my dreams.

fun fact about the whole O2 tank going boom under the water. instead of exploding like it did when the valve broke off, you would instead get a really dangerous projectile. someone had one of those fall in a pool once, valve busted off and off it went crashing into the wall and making a hole. they found the damn thing around 15 meters away from the wall of the pool. so in short no it would not explode with a tap like that. instead it would shear off the valve, rocketing at the nearest wall.

Yaaaasssss, I’ve been waiting for you to do this movie!!! Love this channel

Wow didn't expect a video on Charles Angels: Full Throttle from you, gotta be one of my favorite monster movies of all time.

I remembered this movie. I always thought the alteration ability of the symbiote (Even I figured that one out) was an interesting thing. The writers where pissed and ripped this movie to shreds as they pretty much changed a few details and got the movie the decent made. The one with the cave ladies. Apparently all the monster changes and such was the director. Both worked, both had their thing. For me the real intersting thing would have been to see what a series would have been following the releases of that symbiote into the world.

Hey there, been watching since your old Dead Space videos. If you want to get into the "Gaming" part of Roanoke Gaming, may I suggest the Hive from Destiny 2. Each member of the species is implanted with a parasite which develops a symbiotic relationship with the host. It would be interesting to hear your take on the biology of this alien species.

You are so descriptive and keen on detail, it's great.

Great vid! I forgot all about this flick… would have loved to see much more of those creatures!

Since you subtly mentioned predators hidden/camouflaged as a cloud, you should do a video on Nope and the anatomy the alien in it! It would be great to see what you think of it.

Hey Roanoke, could you take a look at the movie Ginger Snaps? I want to know how a virus could change the body from simian to lycanthrope and if that's even possible.

Got real hype for a moment thinking you were reviewing that parasite show. Eventually it'll happen I'm sure. Also kinda similar in plot to this ironically.

Omg yay I commented about this movie a while back. How exciting!

Would liked to have seen a sequel to The Cave even just in writing.

"This same process also means Dr. Jennings is a punk ass" Man I love this channel

I watched this movie last night with memories of watching your video a year ago. Thank you for the chance to nerd out!😊

THANK YOU ROANOKE, I hope you liked the reccomendation on a movie/video. Its a movie i enjoyed. And i absolutly loved the refrences you made, ill never see this movie the same again

I didn't know I wanted to see someone make a version of Charlie's Angels where they fight cave monsters until I saw this video, so thanks for that I guess.

I watched this movie like three times and I always thought there was supposed to be some sort of Psychosis effect inside the cave that was slowly driving people insane. I feel like there was supposed to be a bigger supernatural aspect that was ultimately disregarded in the final cut.

12:02 that amusingly specific game reference also reminded me of Prince of Persia, which is even more amusing when I think about some dude running across walls and rooftops to shank people.

Man I used to LOVE this movie when I was younger. Great stuff. Thanks for the great video

I actually wonder, would it really destroy the human once it gets out? The monster form was only so that it could survive the cave system. So hypothetically would it really need to change the human that much once it is outside? I kind of want to see what happened after the end of the movie. Would it infect every human on Earth or would it just take over a select group that it could use; such as politicians or religious leaders? Would humans at large detect it or could it take over the world with no one noticing it? Would it completely take over the human and use the original consciousness only for memories or would it just sit back and relax in the human body as we go about our days providing it a safe shelter in the dominant species? Honestly speaking, if it is smart enough now to realize, leaving the human sentient might be advantageous. Perhaps just guiding the human or merging the two consciousnesses together into a new better blended sentience.

Could you do the crazy blind pterosaur-bat-pirhana creatures from The Silence? That'd be a fun one.

thx dr. acula definitely need to tell us more about your experience in romanian cave exploring 😉

This was a really cool breakdown of the closed evolution of Charlie's Angels :D

This seems to be going for a realistic Vampire narrative spread by demons. I really like when writers get the idea to make mythical creatures into hypothetical real world organisms.

I'd say that the symbiosis people want would be classified as something along the lines of 'Sapient Symbiosis'. Yes that's not a real thing, I know, but it's pretty much the only thing I can think of as a potential name for that type of classification, where the invading symbiote bonds but leaves conscious thought alone as the two(or more) organisms work together to survive.

Thank you! I've been waiting for this one! Could you please do A Cure for Wellness??

🔥 Dude never fails to captivate me 🔥 One of the best film breakdowns and deep dives 💪😉 keep up the grind brother

I feel like it doesn't specifically help you live in a cave I think it helps you survive in the specific environment that you are currently living in

As usual, the most unrealistic aspect of this movie is how good looking all the scientists are.

Let's go I was waiting for this video

FINALLY YOU DID THE CAVE!!!!! Thanks a bunch dude, I hope you keep making great vids. I got one more for you to check out, it's called don't be afraid of the dark, there's a 1 and 2 for the movie. Lots of Love Roanoke!!!!!

I activated my almonds and immediately clicked on the vid

Okay, the line "thank goodness no one in this party is named Amy" made me giggle so hard I had to stop the video. The Ruins is one of my favorite movies (guilty pleasure). I even went and read the book after watching the movie the first couple of times. Amy is trash 🤣😂🤣

Your videos are unimaginably interesting thank you

This kept my attention and enjoyed this! Take my sub!

Man I love your vids but the theatre thing going on around the video itself is a little too big, not complaining, but making it just a tad smaller would be nicer

I have sooo many movie recommendations to give should I write them down on comment hence the discord isnt available for recommendations Also therere far too many entirely isolated places throughout the planet like lake vostok and all other subterrenean river lake systems throghout the antartica continent they represent the space ice ocean moons in a perfect manner

I’m commenting before I watch the video! I am so excited that you have finally covered this video! I don’t care what you say the fact that you have covered this is an instant like! Might change after I watch but I doubt it I love this movie!

sweet ive been waiting for this super excited
