Normally when people talk about "symbiosis", they're talking about two or more different organisms cooperating to better survive and reproduce. The classical definition of symbiosis is actually much broader than this, and for good reason. Here we will look how evolutionary biologists understand symbiosis, all its different forms, and why it matters!

The claim that caching acorns allows rainwater to leach out the tannins was confirmed by one study (the blue-jay paper above), but results failed to be duplicated in a followup study.

Brilliant - I'll never quite look a squirrels in the same way again!
Ye im not gonna wach thid vid it soundd like it will make me hate one of my fav animals
@@maevedarcy i feed squirrels
Squirrels are nature's fluffy little gardeners.
Robert also fluffy little fetus eaters

O_o
Unlike humans, animals care for their environment and their homes but we are to ignorant and lazy to ever realise this
Uhm hey uhh did you say say that your name is John Perry. Because if that’s the case I now believe you to be my father because you have my surname (Perry) and you unlike everyone else I could find you stated my perception of all life clearly and i know I have bad luck but that didn’t feel like a coincidence at all
No my name is izaac not Jason, that’s my fathers name (or is it)
Edit: I’m not talking to Robert f I’m talking to the stated clearly guy I put this here because this Is the first comment page so the chance of seeing this would be higher
Wow! This was really, really good and informative!
I have other examples
Humans and honeyeaters
Humans and rats
Humans and raptors (the bird kind not the Owen Grady kind)
Humans and pigs
Humans and sheep
Humans and dogs
Humans and chickens
Humans and beavers
Humans and cows
Humans and horses
Humans and just about every pet imaginable
Humans and bees
Humans and sometimes spiders
Just heard "Sucka" in the middle of a Stated Clearly video!! Still in shock...
That's ticks for ya
Squirrels use my garden beds to stash acorns and peanuts...I find sprouts every spring!
Please tell me you put them back
Squirrels hibernate for months without any food so if they can’t find there food stash quick enough they will starve to death
This is the most underrated channel on TH-cam.
So glad to hear you lovely voice again, it’s been too long
gay
Pooker Yert You’re so dumb, is that meant to be offensive?
U hev gay
Fantastic. the cholera geographical strains divergence was totally unknown to me.
This video actually gives you a great strategy to beat the game Plague Inc. at max difficulty.
this comment hurts in 2020 🙃
Gg lol
@Garth lol i have the game and it might actually help
*tHeY cOnsUmE tHe fLeSh oF tHe oAk tReEs uNborN cHilDreN*
Wow, ill never be able to look at squirrels the same way again.
ouch
This is awesome. The dynamic continuum you keep flashing back to really puts the video format to good use. I can see kids getting a lot out of that.
And I learned more about squirrels! I always thought seed dispersion was only about eating and pooping. Maybe it's commonplace for other people, but this was wonderful information I might never have run across on my own.
I didn’t know about the detoxifying reason either
I come here every time just to finish the video with a happy mind, thank you John♡
Finally a real long length animated vid 😭 form you
As always you are, in fact, clear in your statements. The illustrations are fun, too.
Wonderfully informative as always. Thank you!
Well sir… I really appreciated this video. Thank you for being so informative and articulate.
John, you should make video about ‘life history’, I‘ve always found that a pretty vague concept
Agreed
I enjoy watching and learning from your videos ... BIG THANK YOU.
The way he explain is so creative 100% love it!
Such a good channel, it's only a matter of time before more people watch it!
Excellent! I really appreciate your super-informative videos....Thanks!!
That was truly beautiful. We sure learn every day.
The Cholera study has to be repeated in the south and south-east Asia. This area is basically a kinda native habitat for Vibrio cholerae, but things have changed a lot in the last few decades. A sanitary flushing toilet is now almost common everywhere except for some slums. Cholera has almost vanished as well, but maybe actually its the commensal form that is wandering around.
Great job, John! Carry on! :)
Great animations!
Loved this vid thx stated clearly
this is one of my 1 favourite channel
Thanks for this video!
Helped me a ton on science project. Thank you.
Amazing video great job 👏
Might be a silly assumption, but could the relationship between man and pet be argued as a “social symbiosis”?
Pets receive regular nourishment from humans, humans receive emotional support/relief from relationships with pets
I am most definitely speaking out of my rear but I’m just curious if this has been considered
Another thing: maybe pets (depending on the species) developing more pro-social behaviors with other species could be considered a benefit from domestication
Again, just speculating here
yes. pets fit the definition of symbiosis.
thank you for the help
I had a test on this and dis totally helped me thx soo much🙏🙏
WE ABSORB BACTERIA POOP?
If you're trying to say is me and my Dog have a (Mutualistic) Symbiotic Relationship, I agree!
'We are UNLIKE organisms.'
This was very helpful
So Symbiosic creatures can be friends, enemies or frenemies.
Pretty much Spidey and Venom
wow this video helped me.because from school i am making a Symbiosis project
That is some quality content.
It help me very well. I love it
out of topic but his voice is so calming
great video
I like ur explanation
Millions of years ago, I used to live on mars. I've evolved so much. Did I lie?
That was a lot better than I thought it would be.
*yum yum*
Cool video Stated Clearly.🙂
Clown fish: if you keep me from getting killed and I eaten, I will sh!t in your mouth..forever
Anemone: you got a deal!
Clown fish are hilarious
Thank you!
thank you for these videos. commenting for the algorithm.
Love these videos. Yum yum!!
Are there any examples of symtriosis, eg 3 or more organisms working together?
This helped me
Good vid, ma boy!
i love these videos
when he says yum yum im like XD
Symbiosis stated clearly-thanks
Hai 😁
Awesome! ^^
thank you
a question . if lichens are a symbiosis of many organisms , why do they have single scientific names ? eg: Cladonia cristatella
Genuinely looking for an answer . this is one of the 2 biology paradoxes i struggle with
thanks
Sorry how about the parasite found in luguminant stomach help in digestion is it parasitism or mutualism
We are our own ecosystem. All of our cells, beneficial bacterias and germs in our body working in harmonious symbiotic manner!!! Life is truly amazing and mysterious!
would I be allowed to use some vocal chops from this in a song if I give credit?
Sure
i liked the squirrel animations
Are plants and animals as a whole in a symbiotic relationship?
No. Plants are the primary energy producers, some plants can just live by themselves, and others have found symbioses with animals. However, land plants and land fungi... now that could be a different story.
Probably as parasites
Thanks i have a science test tommorow and i had to understand symbiosis
Plants cultivated for human use, Mutualism?
Both you and I can have a symbiotic relationship
Nope That would be parasitic because were killing the plant in the process and plants release oxygen and if there’s no oxygen we all die
@@jasonperry7428 are you sure about that. Because we create carbon dioxide and plant needs carbon dioxide and plants convert them into oxygen that benefits us and other organisms
It's like Eddie Brock and the symbiote.
Funny and helpful
That's is how to learning
awesome!!!!!!!!!!
if teachers explained like this man!!!
Is there a way to make a one-time donation? I want to use part of this as a listening exercise for my ESL students and would like to show my appreciation, but since I live in China, I try not to lock myself into financial commitments I can't control easily from the other side of the world.
Yes, you can do so via our website here: statedclearly.com/contribute/donate/
Wow just wow😮
“Yum yum”
Who else expected a mention to chloroplasts and mitochondria?
YUM YUM!
this saved me from watching 3 hours of videos thank you
the. most underrated comment…
i dont wanna watch it i dont think its gonna end
Please can we get a t-shirt with the squirrel consuming the flesh of the unborn children of oak trees???
I literally just got finished watching a Smithsonisn Channel video about Angler fish and hoe the male and female have some sort of parasitic symbiosis going on, though they didn't explain why it was parasitic. If the male gives the sperm and takes nutrients then it's win/win right? Isn't the goal of the female to reproduce?
So symbiosis can also contribute to co evolution
Free delivery lol
So, domestication is comensalism?
Yum yum
So trees are secretly hoping for the death of squirrels oof
I love how you address the school science curriculum dot points. Cheers Jon!
Also, thanks for saying anemone fish is mutualism. Textbooks always say comensalism. I just tell the kids whoever thinks that obviously has never seen it!
Symbiotic like me and my dog!

We...are venom!
y u m y u m
Sick video
I came here to study
Yum yum 😋
Speed dispersal
Why invent a new word if you can simply redefine the meaning of an existing word?

Symbiosis is the most difficult niche of evolution.Симбиоз - самая трудная ниша эволюции.
