Charles Darwin encountered a tiny fox-like creature during his famous voyage but instead of discovering its fascinating evolutionary story, he just knocked it on the head with his geology hammer.
Thanks as always to Julio Lacerda ( / juliotheartist ) for the tremendous reconstruction of Darwin's Fox!

It's just a small thing, but I find it funny that the bush dog and maned wolf are off on their little branch with the shortest and longest legs respectively.
Kinda like how dogs are
That is pretty silly
@@apolloandwarrior_3229 its NOT silly . its dog !
"I use my heels the size I want!"
i wish there was a maned wolf pokemon. make it a regional lycanroc or something
Darwin: The greatest naturalist who ever lived
Also Darwin: Violently bonged the head of a smol curious doggo with a hammer
Maybe Darvin left parts of the story out that would condem the dog to horny jail.
🤣
And the sad part is, Darwin sat on his discovery for 20 years out of fear religious thugs attacking him (and it really happened, Darwin was verbally assaulted dozens if not hundreds of times and his theory was rabidly torn apart, but he was lucky a few young atheist biologists like Thomas Henry Huxley adopted his thinking as it was based on prof, not stone age voodoo, and started vigorously fighting back, or the theory of evolution would be buried and forgotten for the next century)...
@@KuK137 Darwin also experimented with the sea iguanas of the Galapagos by throwing them in the water and watching them swim back to land, where he caught them and threw them back. He was demonstrating that these creatures instinct said that they were safer on land when in danger, even if the danger was a lizard-throwing naturalist. Probably fun for Darwin, and non-lethal for the iguana.
This is before we all became soft naive little balls, living in luxury.
Super relieved when they showed some real life footage of it. I was really scared we’d gone and done another extinction.
Eggstinct
Almost. But not quite
They are endangered and number in the hundreds, so don't be that relieved.
yes, but thanks to domestic/feral dogs, among other things, they are now quite threatened.
Darwin: "Go to horny jail" *bonk*
I’m so early, the Cambrian explosion hasn’t started yet
Avalon explosion?
I'm still waiting for the Big Bang to start. 💥
I understand that completely. I lit the fuse, and am still waiting on the big bang…
@@itwasagoodideaatthetime7980 Same. Waiting for the Planck Epoch rn.
Booo
Everyone missed every example of evolution right under all of our noses until Darwin at one point suddenly stopped missing them.
Technically evolution to some level was being worked on before. What Darwin really started is realizing how much of the process tied into natural selection rather than being solely based on something like lamarkian evolution. While things like epigenetics have brought up aspects of those periods in super specific areas, this realisation around natural selection was what truely ended up creating modern biology
And the sad part is, Darwin sat on his discovery for 20 years out of fear religious thugs attacking him (and it really happened, Darwin was verbally assaulted dozens if not hundreds of times and his theory was rabidly torn apart, but he was lucky a few young atheist biologists like Thomas Henry Huxley adopted his thinking as it was based on prof, not stone age voodoo, and started vigorously fighting back, or the theory of evolution would be buried and forgotten for the next century)...
@@KuK137 If something new comes along that fundamentally shifts the way humanity view themselves ans everything around them. It shifts our sense of who and what we are...
If something like that comes along there is absolutely always going to be a significant pushback, anxiety and unrest.
Move on. You're team science and ur winning.
It is not weird that a majority fundamentally religious world population dont have a smooth transition phase
I remember learning about a pre-Darwin biologist called Wallace, who found evidence of evolution (called "transmutation" back then) when he discovered several species of beetle in Australia(?) that looked similar to each other. I can't remember most of the details, though.
It’s become more fashionable to dump on Darwin, but in the end, it’s over details, and the fact remains, he got mostly, astoundingly right.
It's so interesting to see how a natural corridor allowed canids to find these ecological opportunities and expand their territory. Ironically, now, we have to create corridors like this one to save species. Our crew recently filmed a project that aims to create a jaguar corridor through south and central America to save the species. Jaguars lost 50% of their natural habitat, which makes it harder for them to find each other and reproduce. Travelling wouldn't be a problem for them, but the territory they have to cross to reach protected areas are roads, and croplands, making everything extremely dangerous for them. On the positive side, the project is already showing promising results.
Wow. Thanks for covering this. I am happy that the government there are taking steps to revive thjs magnificent beast's population
❤️
More of these corridors are needed. In a number of places around the world there are dedicated bridges for wildlife to safely pass between areas that are bifurcated by man-made structures. Still, there aren't nearly enough and far more are needed.
Yes indeed. Florida also is creating natural corridors to help the florida Panther rebound back from the bring of extinction. Originally they roamed all of the SE USA. But now there are only 250 left with only breeding population in SW florida.
Hopefully they allow these bills to pass to protect the Florida Panther; bc there’s only so many pieces of unspoiled paradise left.

The "Eons" series on TH-cam is one of the better 'educational' series. Hope the series continues for a long time. Kudos to all the staff for making this series such a learning experience.
"and the origin of these species?"
Nice one. 10 stars
Impressive, let's see Paul Allen's.
@@HaloJumper7 oh uhh.... starts sweating
@@HaloJumper7 Perfect comment!
That's a lot of invulnerability! *starts humming Mario invincible music *
That "meaned wolf" is called "aguará guazú" here in Argentina.
It means Big Fox in Guaraní (one of the multiple tribes that lived in what is know today as Entre Ríos).
It's called lobo guará (lit. Guará wolf) in Brazil!
Ueeep!
After their great extinction by colonial expeditions.
@@Alusnovalotus they are not extinct yet neither the Guaraní culture nor the Aguará guazú.
They are in danger yes, but because of modern reasons.
Yes colonialism had a lot yo do with it.
And the Darwin fox is called Payneguru in Mapudungun.
There's actually a frog species discovered by Darwin in Chile. Now is called "Ranita de Darwin" and it is small. Like, a really small frog. Darwin did a lot of research when traveling in this piece of land. Amazing, to say the least.
You broke my heart with that fox story 😭
And that hammer at the end? 😧
I imagined something less deadly...
Great informative video… that also made me dislike Darwin a bit
i mean on one hand we wouldn't have scientific knowledge without darwin
but on the other hand, the number of rare exotic animals he clubbed, shot, skinned and dissected for science, as well as the galapagos tortoises he cooked and ate...😭😭😭
Sometime science is cruel
@@chubbrock659 even when it doesn't need to be, which is just... wrong.
In some parallel universe, Darwin stayed in mainland South America long enough to take notes on the different canids and foxes became synonymous with evolution instead of finches.
that's a run on sentence my friend
@@qAngel Darwin woulda had to run around SA to get the picture. So that's appro. But the finches were a much simpler example, the process was much more obvious and recent. Also the Mockingbirds gave him a big big clue. I like the idea of Darwin going native in the Amazon and discovering ayahuasca and fox evolution.
They got us in the last half.
Imagine being hit by a hammer and then named after the person who killed you
Oh wow, I never knew the South American canids are all so closely related! I always thought the New World Foxes came from Old World Foxes while the Bush Dog and Maned Wolf was their own thing. That’s REALLY COOL!
That is very interesting. I was impressed with how long that wolf's legs were
@@markdodd1152 sure is. I always imagine they're using high knee boots. 🤣
It's weird to me call them maned. We call them Guará wolf's, Guará means Red in tupi.
@@AramatiPaz too funny., they would rock knee high boots . They look more like a Fox too . So Guarà makes sense to me
North American foxes ARE related to Old World foxes, but all the South American canids are more closely related to the common ancestor of wolves, coyotes, and jackals.
@@NovaSaber- I knew that given enough time, crustaceans evolve into crabs. It seems canids evolve into foxes, too.
I am a Palaeolithic archaeogist. My kids, like so many, are obsessed with ancient animals and evolution. This PBS series is extremely praisewothy as it does not only explain why happened in the past and why, but it also explains the epistomology of the disciplines that investigate the past and teaches children (and adults!) how we know what we know and why we conclude it is true. So we learn about theories of knowledge and how to apply them. Unfortubately, this is something not adequately taught --if it is taught at all -- in most of our public schools where children are not encouraged to question and explore, but rather are rewarded for demonstrating their indoctrination into unchallenged "systems of belief" reinforced by rote memorization. Thus we have a population that accepts without question what they have been told most loudly and with most repetition, and is suspicious even antagonistic to scientific inquiry.
I mean you can thank religion for normalizing childhood indoctrination and brainwashing. I mean religion in of itself is antagonistic to scientific inquiry as where science is willing to say "I don't know, let me put together falsifiable hypotheses and test them until I come upon one I cannot disprove" while religion asserts "this is true, this is fact." Usually without explanation.
I was with u till u started making broad generalizations about the state of public education in the US. you’re allowed to praise a small subset of free online educational content without ragging on the incredibly diverse systems of education people experience in one of the most populous countries in the world
Blah blah blah....
@@bowhunter8532 and?...
Sometimes I go a few weeks without watching an Eons episode, I sort of forget, and then it can be almost surprising how incredibly high quality they are. Also this one was just particularly interesting. 👍
Darwin just casually icing that fox with his mallet, like it's the natural first impulse to have when you see an animal you haven't encountered before. Yeah... This guy was a biologist alright. 😅
In the future: Dr. Soandso collecting cosmic rays, so cruel! Let them free
Yeah, the more you read about the history of biology the more you learn that "collecting" is a euphemism
Really wouldn't have guessed how closely related the Bush Dog and Maned Wolf are!
@Merileopardi Saksassa - The Bush Dog looks like the Corgi of foxes.
So Darwin’s fox isn’t a true fox but a fox-like wolf.
Some call it "Darwin's Zorro". IDEKY.
It's neither. Darwin's fox is a canid, but is in its own group, distinct from the genera Vulpes (true foxes) and Canis (wolves, dogs, jackals, coyotes).
@@gleswick8399 Some jackals are not in the canis genus, instead they are in the lupulella genus.
@@kaisserkjj2216 Oh damn! Last time I checked, they were in Canis, haha. Taxonomy really is a science where by the time you turn around, some taxon is put somewhere else.
Kallie's book is awesome! I read through almost the entire thing in one night, but it covers a huge variety of prehistoric topics, a lot of which are based on Eons videos! My favorite page is the Ediacaran spread.
Darwin gave that fox the Darwin award? damn it, Darwin.
@m33p0 - I hope the poor innocent thing bled all over him.
Humans are agents of evolution too.
I got 10 seconds in before I gasped, paused, and immediately bought your book for my son. Reviewing its details for how amazing it would be for him was almost just a formality.
It's exactly the kind of book I would have loved as a kid! Hope your son gets a lot of enjoyment from it!
In Argentina and everywhere were the maned wolf are called aguara guazú which in guarani language means "big fox". It's so strange to hear it being called maned wolf 😯
In Brazil, it is called "lobo-guará" (guará wolf).
I still can't get over the fact he knocked a fox unconscious 💀
Yeah people are gross. New animal? Lets kill it!
Ummm...I guess technically the critter was knocked “unconscious”, but “dead” is more precise.
Love the episode!! Also video suggestion, dire wolf again? Especially with new info about them and them not being related to wolves? And again this episode was great!!
"Hm...what an interesting and curious creature"
Man: I'm gonna kill it
I can’t wait to get your book Kallie! (: Thanks for sharing
I love the maned wolf. At first I thought it was a fox, so finding out it was a wolf was a big surprise. It is the most graceful and delicate canid ever.
Apparently it's neither, but its own thing as is the bush dog. More closely related to foxes than wolves as this video shows.
Its not a wolf. True wolves never made it to South America. Thanks to the Andes, it still remains ecologically, an island continent.
I found this video to be particularly fascinating. So interesting how South American canids diversified so quickly!
That is one super adorable little fox - shaaame Darwin!
1:14 We have a fox around here (southern Oregon) that resembles the fox directly behind Darwin's fox on the chart. It looks very much like a cat. When I first saw one I called it a "cat-squirrel". Typed it into Google and found out it was closer to a dog!
I'm very happy to share that i worked for a few months with the ministry of environment about the conservation of this fox (among other species too!). i'm no longer helping but i hope the conservation efforts are going well and bureocracy can be defeated
That’s so cool!
Darwin, how dare!
we often forget the evolution of beauty. nature just has such a way about her 🥰
@Hollie Gould - Too true, Hollie.
Learned many new facts today. Thanks for covering these amazing canids.
Imagine you're a curious little fox and suddenly *BONK*
It was the ignorance that killed the canid, curiosity was framed.
Congratulations Kallie, on your new book release. Looks amazing. I'm going to enjoy reading it with my grandson! 🙏🏼😻📖
Doggone, that poor little fox that Darwin whacked had it ruff!
At first I thought this said Darwin whacked it off
Thus was super fascinating, I loved that you took us on this journey.
Congrats on the book! 🎉
1:24 - Look at those lovely red-brown ears against that salt-and-pepper background! Awesome!
stilt dog is closely related to potato dog, didnt see that coming.
Beautiful, smart, charming, and an author! She has it all, folks! 😃🥰
Stop hitting on the hosts.
And owner of amazing hair, don't forget the amazing hair
Congrats on the book Kallie!
I have never heard of bush dogs before, and I think I have a new favourite animal now.
CONGRATS to Daniel Chávez et al (2022) for their beautiful work!! Thanks for this!
Amazing the the spread of the South American canids went all along the southern end of the Andes.
I wonder if that was the case for more invading mammals like the felines and the lama's.
The fact the ‘most recently’ in this video context is a scale of 2 million years is absolutely fascinating, comparing against 80 years of our life span, it’s a reminder that how trivial our lives are.
Have fun!
Can we just take a moment to appreciate that in the beautiful graphic of Darwin's Fox, you can see Darwin's shadow looming behind him with the hammer raised?
On one hand he's sorta of s personal hero of naturalists and biologists and he changed the world
On the other it was still an old timer naturalists so as predictable with the times he really just turned the fox into pass tense
I appreciate the recognitions given to native peoples and native land. Nia’wen!
I just asked my local public library to purchase Kallie's book--I hope they do, so I and lots of others can read it! Regarding Darwin bonking that poor fox, I guess it helps to remember that, unlike a modern naturalist, Darwin couldn't take photos or videos of it, and I'm guessing he understood he might never again have the chance to visit that part of the world, so he probably felt he couldn't pass up the opportunity to get a specimen of that species, while he could.
@brad Thank you Brad, for your thoughtful post.
Darwin is one of the early Scientists I admire the most. It's discouraging to think that he would mindlessly kill an animal.
Your rational and balanced analysis has restored my faith in Darwin. I bet he muttered "sorry little fella" after the fact.
He wasn't a brute !
Thank you again and new years greetings from Auckland New Zealand 🎉
It's always very funny when someone talks about a million years period as "fairly recent". 😉😁
Thank you for your wonderful presentation. I really enjoyed learning about these Amazing Canids.
Best wishes with your beautiful book 📕♥️🏆🌹🌞🌷🌺💐🌸💐🌷🌻
Congrats on becoming a published author!
congrats on your book!!
So Darwin essentially did the cat in the hat baseball bat meme on this fox
I love the PBS Eons series. Me watching the videos like, “What do I gotta do to work here?!” Looks like a lot of fun 🤩
Kallie is great, her energy is amazing
Congrats on the book Kallie!!!! I have a niece and nephew who're JUST the right age for it, so this is fabulous timing hehe
Hey guys!! I love your videos, and I had a question for maybe a future episode :) it’s been long debated about how massive sauropods managed to get blood to their brain. Some say they had one big heart, but it’s been argued the blood would be too slow and gravity would bring it back down. Other’s say there was more than one heart! I’d love to see what kind of research about that you guys can find :)
Always well presented! Thank you PBS!
Somehow, the Bush dog looks like a CGI! Their resemblance to bears is evident too, and it almost feels like what an early canid ancestor might've looked like :O
Fun fact, the earliest canid found, hesperocyon (dates back 40-37 million years) looked like a big weasel mixed with a dog
@@kaisserkjj2216 A deasel?
I’m always so happy to see a new video from you guys ❤
I have 2 copies of your book Kallie, one for me and one for my nephew. I love it and cannot wait to gift my nephew his 🥰
I love PBS. Thank for countless years of Top Notch programming for young people all the way up. PBS is truly the best TV on TV
It's pretty great!
The mural at 2:30 is in the New Mexico Museum of Natural History and Science, where I was a junior docent for five years. I miss the Southwest so much sometimes. If any of the volunteer coordinators are reading this... please bring back the bat cart! 🦇🖤
Also, congrats on your book!
Kallie,
Thanks again for your enthusiasm in presenting the science I love so much.
How is no one talking about how cute Darwin's Fox is?
sheep
@@michaelanderson7715 yes, sheep are also cute
@@nmarbletoe8210 gimp
-So many ecological niches you can occupy?
-Yes
Congratulations on publishing your book 🎉🥳
This episode is like science becoming poetry. And with dogs!!!
congratulations for ur book, i hope its a great hit
Poor little fox. :´(
It was just curious. *Bop!*
Congratulations on the Book 📚... 👍👍👍
Just ordered, Callie; Amazon delivers TOMORROW. Congratulations!
Can you do a segment on the evolution of hippos?
This channel gives me great appreciation for science.
Nice video and congrats on the book!
Poor fox - probably met some nice humans before.
Really liked all the graphics in this one. You guys have been killing it!
I'm generally not too into birds, but now I really really want a video explaining these Terror Birds you mentioned
They already did that video.
@@AndrewTBP Thanks! Looked it up, and it was great.
Congratulations on your books publication!!!
Very interesting and informative as usual. Amazing fluency and eloquence.
Upon seeing the Andes Mountains, have anyone wonder what will the South America looked like if such mountain ranges do not exist?
Well for one, the Amazon rainforest wouldn’t be as grand as its development was assisted by the Andes, with rivers coming down the mountains and flowing out to sea
I get the feeling that Indigenous peoples in South America were (and still mostly are) not happy about their animals being named by colonial scientists (including this fox).
I get the feeling you don’t know much
Calling that fox a colonial scientist is oddly correct. It colonized South America by studying the ecosystem and finding opportunities to engage in trade.
@nmarbletoe Thanks for your short and witty post! I laughed out loud 😅
Truth is, we are ALL from somewhere else !
Humans, animals, birds, and fish.
All our living ancestors moved around through eons of earth's many geological and climactic upheavals.
You encapsulated this in a few clever words !!
Thanks and greetings from Auckland, New Zealand 🇳🇿
Also, what is a parents favorite kind of dinosaur?
The plesiosaur lol
Least favorite?
Agrosaurus
@@nmarbletoe8210 lol
Congratulations on publishing your book! Yay, you! Thank you!
I would love to see a similar study on eurasiafrican canids
Absolutely absorbing episode.
Poor fox killed by Darwin for being curious.
Ok idk if anyone else noticed this but the shadow of Darwin raising his hammer in the Darwin's fox illustration is terrifying.
Do you know how you track genetic relationships among unicellular plants? Algae-rithms.
Well done canids! I too, aspire to radiate and diversify into all available niches! 😃
😂
No one:
Darwin: I've never seen that animal before. Let's kill it. 😬
Congrats on the book!!
Love it! It's great to watch more stories that are based in Southamerica :) please more!!
What’s the difference between a carnivore and a hyper-carnivore?
A carnivore eats mostly meat and a hyper carnivore eats over 90% meat
VERY cool. great video, I love the topics you choose
Congratulations on your book !!
