The Discovery of the "Missing Link"
Вставка
- Опубліковано 18 жов 2024
- Hi! Today we’ll be covering the discovery of Tiktaalik, which was a huge find for the vertebrate transition to land. Tiktaalik, on its own, is really cool, and has features that really make it appear to be a “half and half” - half fish half tetrapod. But the discovery of it is even cooler. It’s actually one of the coolest things I learned in college. So I’m going to share it with you. I’ll give you a quick rundown of the vertebrate transition to land, and introduce you to this fossil that changed everything.
A MASSIVE thanks to Gian for the editing!
PATREON!!

In the Late Devonian, Tiktaalik crawled out of the water. This has made a lot of people very angry and been widely regarded as a bad move.
I need to re read hitchhikers guide
The estate of Mr. Douglas Adams approves of the above comment.
so long and no thanks @ the fish
😂 everyone in this comment thread has a towel handy
Don't panic!
Apparently a factor in pro democratic voting, much to the chagrin of of the Donald party. (Also Palestinians exist)
I’m an Inuk from the arctic and I was so proud to learn that Tiktaalik had an Inuit name because it was found in the arctic.
It was only fitting that the discoverers gave this species an Inuit name based on where its fossils were found.
The only time they actually valued the natives and didn’t name it something latin, probably.
@@brídeann it's becoming a more common practice 🤓
@@AnnoyingNewsletters good 👍
The Arctic has yielded a ton of important science, ice cores from Greenland have helped us map climatic changes from this era and I also believe that some of the oldest rocks ever found were found on Greenland so that has helped us date the age of the Earth itself.
That damn fish, now I gotta pay my taxes.
Oh shit almost forgot my taxes!
Edit: Did my taxes! 🥲
Now we need special curse words to blame Tiktaalik when life deals us a bad hand...fin... ray-fin with wrists...
So go back into the water 🌊
Oi don't blame our grand family for what the government did. Just blame the government
Move to Somalia.
Whales then decided "nah let's get back into the water and become super massive"
They noped back 😂
They made a smart decision.

*Unevolves myself*
Maybe we should follow the whales and go back too 😂
"he's crazy, he plays fetch like a dog" is a great outro, and also describes my cat
Mine too!
My cat too!
Mine as well, she's been bringing me back the toys I throw for her since she's like 6 months old
Mine too! He’s the first cat of 5 my whole life to do it I feel so lucky he also sits haha
Can confirm, had a cat that thought he was a dog (or, maybe a small tiger). Played fetch, knew how to sit, followed me on command, and loved sleeping in between my legs at night.
To all those complaining that Tiktaalik ruined everything by moving on land, we would not have all those great Lindsay videos to watch if it had not.
Ted Daeschler was one of my teachers last year and now I work at the museum he has been working at. One of the kindest, sweetest, smartest men I have ever met. I am so glad you mentioned him as many people don’t. Last year (educational time frame wise) was his last year as a teacher, (so proud to be the last class he taught). He is now retired so he can focus on research and doing expeditions. Before retiring, he was the curator of the Academy of Natural Sciences, in Vertebrate Paleontology, Mammalogy, Minerals(sediment). Currently we (the museum) are at a standstill trying to figure everything out when it comes to departments, because those are some huge boots to fill. I just wanted to let everyone know that yeah he wasn’t the main name on the discovery, but he was second in command and a role model to me and many! He never got the recognition but he never asked for it, he just did what he loved!!!
There is only one talk I have found with him on You Tube, it's on my 'Early Tetrapods' playlist
I met him a few years ago! He is very cool
Cats are the true transitional animals. Wherever there is a door, they want to transition through it
And so many trans girls wanna be like them
Unless it’s already open, then they just stare at it and leave, just for you to close it, so that they can actually tell you that they wanna get out
Fun fact: I used to hang out on a forum with Per Ahlberg, who was on the team that found Tiktaalik, and we got to hear about it in tiny pieces before it was made public. I remember doing the creationist "two more gaps!" chant all the way back then.
The fish that ruined everything
It's just so horrible; we're on the same page
It's my 13th reason why?

Amazing work Lindsay! And for those who are interested I would seriously recommend 'Your Inner Fish' by Neil Shubin, which elucidates a LOT about paleontology and evolution and the importance of the discovery of Tiktaalik. (Its name is from the Inuktitut language as sugggested by some Inuit leaders)
LOVE to see the word 'elucidate(s)' out in the wild!!
Yes! Highly recommend! My A & P teacher loved Neil’s book so much he put extra credit questions related to info from Your Inner Fish on each test. I read it initially for the extra points but ended up loving it so much I gave copies to several friends and family as gifts. Wonderfully written and extraordinarily entertaining!
I've seen that! It's really good
An extremely informative book indeed.
Thanks for the recommendation! I was feeling lost because I'm almost finished with my last library book and none of my book orders are ready yet 😭
“You can’t just go to a local park…” Actually, my town *does* have a fossil bed in a local park. (No T-Rex bones, though.) I think I took this for granted as a little kid-assumed a fossil bed, like a post office and grocery store-was just something towns had. Got a bit older, realized it was more of an unusual thing. Became an adult, read a book about paleontology, saw a mention of my town’s fossil beds, and almost yelled out in the middle of the library, “OMG, it’s Poricy Park!”
There are entire countries that barely have any fossils at all.
@@hedgehog3180 Denmark is, quite literally, a pile of gravel dragged here by a glacier that then melted. We find fossilized urchins because the ocean is kind enough to wash some up for us now and again. And that was the entire history of Denmark's contribution to humankind's understanding of fossils.
@@andersjjensen That's interesting! As someone who live in a place in Asia that's fairly new (not mainland) and just being pushed to the surface by tectonic movement million years ago, my island country is also only have new fossils like pre Homo sp. humans, sea creatures, and several other first form of mammals, but no dinosaur fossils at all. Because, well, the lands weren't here yet when the dinosaurs existed, not until hundreds of million years.
@@way9883 That's still a long-ass time ago :P Denmark didn't exist until roughly 11,000 years ago.
You’re right, the story you told is freakin’ awesome. The way you present the information is entertaining and attention grabbing. Thank you for sharing your knowledge 😊
Why did I hear this in her voice
Nice summary of the discovery of Tiktaalik, Lindsay. I read Shubin's book 'You Inner Fish' when it came out, and like you was blown away by the way he used straightforward scientific processes to work out where to look and what to look for. And had the confidence to keep looking all those six Arctic summers until the team found it. Spectacular!
You were a huge part of what encouraged me to go after a biology degree!! Thank you Lindsay.
Moral of the story: We really should stop hating on Tiktaalik and instead direct all of our hate towards Australopithecus for climbing down from the trees.
Or towards Homo habilis who kickstarted the market economy by mass producing tools... what a jerk.
🎶"Australopithecus would really have been sick of us"🎶
More like we really got sick of them deciding to be bipedal.
This is brilliant, I was strictly an iceage guy until your vids covering the history of the Earth............that we know of.
I also suggest:
Aron Ra's 50 part series 'Systematic Classification of Life',
History of the Earth,
Moth Light Media,
Earth.Parts,
Historical Geology with Dr. Chris White',
Geogirl,
Anthony Pain.
And for early Tetrapods specifically I have a big playlist titled 'Early Tetrapods'
And for books on early tetrapods:
At the Waters Edge: Fish With Fingers Whales with Legs' by Carl Zimmer (awesome well rounded intro to the history of tetrapod and proto whale Paleontology and Paleontologists)
'Earth Before The Dinosaurs' by Sebastian Steyer
'Your Inner Fish' by Niel Shubin
'How Vertebrates Left the Water' by Michel Laurin
'Gaining Ground' by Jennifer Clack (THE book on early Tetrapods)
@@whatabouttheearthThanks for the recommendations!
New Lindsay video dropped, yesss but girl RESTOCK THE MERCH!
WORKING ON IT!!
I've seen so many memes saying "I want to go back and beat this thing with my flip-flop" & IT'S SO SAD LMAO! Himb was just trying to evolveeeeeee. As a mortician I love your videos. I deal with decedents all day every day and having your channel postings to look forward to is comforting for me. We're probably the same age but I have the same reverence towards you as I did to my fav science teacher from H.S. just in a para-social BUT RESPECTFUL/healthy way lmao
I love your shirt as well !*
Exactly! Tiktaalic did nothing wrong. It's that stupid monkey who decided to leave the trees and walk around. This is the b we have to get!
I’m doing a project for science class about the periods of the earth and your videos are so helpful because they are both entertaining and interesting! I’m recommending you to all the other groups because you have actually helped me so much 😭
Your use of a niel breen clip from one of the most inadvertently hilarious movie scenes ever has made me a forever fan. I mean, I already was before, but that sealed it.
And tell Coya and new kitty I said "ppppssss, ppppssss, ppppssss, ppppssss, ppppssss"
❤❤

Cats breaking into cinema.
as they should

I’m sick as a dog and I can feel this video healing me. Thank you for this treatment, for now I may live through the night 😂
Fish: I reject water
"I reject my fishness, JoJo!"
- Tiktaalik, probably
375 million years ago, the invention of teen angst was almost identical to its imitators today
Daga kotowaru!!!
Whales: I reject air. *goes back to water**
8:30. Strictly speaking, ANY trip they found it on would have been their final trip 😂. In all seriousness, awesome video!
Haha why is it always the last place you look? 😂
PBS has a three-part series on Neil Shubin's work! It's based on his book, "Your Inner Fish," and it's fantastic. Shubin himself hosts it and he's just delightful :)
I just started watching your videos like 3 days ago, but I'm obsessed. I'm an electrical engineering major and these videos help my brain relax after staring at math equations all day. Also, I need a merch restock!
I'm finding that I have to rewind frequently when my attention lapses because I keep hearing "THIS IS A NO BONE ZONE!!" and having a chuckle.
How I adore the way you shut the creationists DOWN 😂❤ You are THE badass.
Was thinking this this- and the young earthers too.
What to you mean the universe being created by God and evolution are completely compatible ideas I wrote and essay on it.
@@connoisseur428im pretty sure the commenter only means young earth creationists
@@connoisseur428 No, they aren't at all.... An entire essay wouldn't have been necessary if creation held any water, for one.
@@The-Silliest-Little-Guy No. There's no such thing as a god; it's a superstition.
I'm imagining that the person who discovered that fossil was actually literally the direct descendent of the specimen he found. I know he's probably not and it would be insanely unlikely, but imagine discovering and digging up the remains of your direct ancestor from millions and millions of years ago
that's so cool
It's probably not that unlikely. Picture the family tree going back that far, it's descendants must number in the hundreds of millions - especially if it gave birth to hundreds of offspring, like some fish
The cat is such a menace, I love them. XD
Every fossil and living creature anyone has ever seen is a transitional form.
Horseshoe crabs are just doing it reeeaaally slowly
What about LUCA?
@@realdragonit too was a transitional form.
@@EiferBrennan From what?
I've always heard of Tiktaalik and of how big a deal it was, but before now I had never heard the exact how's or why's of it. Thank you for making this video! It is nice to finally know the details of this transitional fossil.
I think Neil and Ted found the missing link first day, first trip but spending time in the Artic is better than dealing with undergrads
A true breakthrough is happening and I swear it’s this comment!!! 😂😂😂
Thank you for the subtitles, we really appreciate it. I love learning from your videos. Been following since tiktok and was surprised to see that your full length vids had captions too ❤
I got the amazing opportunity to meet Ted Daeschler, one of the codiscoverers of Tiktaalik at the Philadelphia Academy of Natural Sciences. He showed me the one of the original molds taken of tiktaalik and their collection outside of public view. It was amazing
god hearing about the years in the arctic is crazy. i went to a fossil dig site as a kid and i only lasted 2 hours lol. they’re turning the site into a museum now and im super excited to see it once it’s complete :)
0:36 me whenever I meet someone I haven’t seen in a few years
Underrated joke, thank you 🫡
Ultimate trans joke
Totally and utterly brilliant! Thank you so much for the well researched information and great presentation. I'm a 65 year old guy from UK, who is binge watching all your videos because I love this subject. I've just been in Agadir Morocco, which used to be joined to East Coast USA (near New York) before the CAMP (Central Atlantic Magmatic Province) break up. In the mountains along that coast, you can find aquatic critter fossils and evidence of really huge volcanic eruptions. So many Trilobites! I'm going back soon to play a gig with a Moroccan rapper but will be out and about in the landscape too. I'll update you if I find anything you might find interesting in the rocks. Keep up the good work and thank you for sharing the detailed knowledge you have. 👍
Love hearing representation for my home state in your videos; can't forget we distinguish the Pennsylvanian Period from within the Carboniferous due to the specific type of coal found in our Appalachians!
Hey, just want to tell you that I'm happy watching your video. As it's remind me of my childhood.
Back then, there was this section at the national newspaper in my country called "geoweek". It basically had a similar content like yours. I learnt how to read from that. I developed an interest to read from that.
Well now, your content kinda gave me a feeling of nostalgia. Besides, now your video also helps me improve my English vocabulary.
Keep up the spirit!!
Love you ❤
Fish coming on to land: it's free real estate
They staked their cla(i)m 😂
4:55 most cat mom face I've ever seen and I love it.
The bigger white screen makes viewing nicer for me, thanks!!!
I gotta say the intro/title card thingy you have is perfect and I hope it never changes
Odie be like "You can't make a video about tetrapods without showing the greatest tetrapod that ever existed!"
I’ve been watching your videos for a while and they’ve been so helpful in my bio class
I was only a fish how I ended up like this? I was only a fish, I WAS ONLY A FISH!!!
I sang that
@@_synchrophasotronme too. 😂
You remind me of Nigel Marven, we used to watch his work (mainly Prehistoric park tbh) with my brother as kids. He's the reason we fell in love with science, paleontology especially. Thanks to You, I again want to learn more about it.
Tiktaalik is one of the coolest fossils ever!!!
That story of the Artic paleontologists is insane! That's too cool, and I've never heard this story.
in 380 million years they'll find our fossils and lament how a civilization decided that words were more important than mutual human decency.
AAAAAHHHH ye said the thing i been waiting for you/anyone to say!!! you're brilliant and amazing! keep doing what you're doing
they did not find tiktaalik while doing roadwork in pennsylvania because penndot has never done anything for anyone and they aren't going to start now
I'm always impressed that construction crews recognise fossils and archaeological finds when they dig them up.
Good to know if I see a chimpanzee in a zoo, That’s my cousin who got locked up for nothing.
keep up the great work. i very much enjoy your content style. The way one, execution makes it relatable to most and hold the attention span. While using, the right names. love it.
A girl I went on a Bumble date on said she met Shubin and spent the entire time showing/explaining Tiktaalik memes. She said he didn't get it
Tonight Tiktaalik has been deemed a very "controversial" species due to their recent decisions on what life should be like, more at 5, back to you Bobby.
I hear people talk a lot about the transition of vertebrates from water to land but what about invertebrates? Specially arthropods. Have you done a video on that?
There are possibly some fossilized millipede tracks that place invertebrates escaping the water around 480 million years ago
why is snail
omg i’ve been waiting for this vid!!! so excited for the next quiz ^^!! your content is always so engaging!!!
My cat also plays fetch - but unlike a dog he drops it for me to throw so he can chase it down, sit on it, and then give it flying lessons. His favourite is "Fishy" which is now lacking eyes, fins or anything much that looks like a fish. Sigh.
OMG a Neil Breen cameo. EXCELLENT
I don’t blame a fish for having more ambition than me
Omg, Lindsay, I already admired you for your academia and comedic timing, but then you came in with the Neil Green and now I worship you
It's never link that's missing, it's always Zelda.
Very cool info, great story AND a Shurbin sighting.
BUT, the very best was Lindsey breaking her 'You learn from ME now, MFer' facial tension and cracking a brief 'I like cats' smile.
Best.episode.ever.
a fish named 🤨 Tik taalik 🤨 being talked about millions of years later on tik tok......ah just an easter egg from the simulation runner.
You forgot to thank Tiktaalik for your cat. 😉
Really appreciating your videos, btw. Informative, fun, the right amount of humour, I love the look, and now I know you’re a cat person. Brilliant.

Congratulations, Science.
You’ve played yourself.
yo eff this fish (i genuinely love science and get so giddy whenever you upload :3 i get to live my animal science dreams vicariously through you)
I personally did not evolve from the Tiktaalik, I emerged from a Gay Lake
So real.
hey me too!
I formed in Bi-salt from a rather spectacular Volcano with blue, pink-magenta, and purple edifices.
I have never thought about the fact that fish don't have necks. It's not that weird, but now that I know it's freaking me out. Thanks for that.
I personally blame the matter anti-matter asymmetry at the big bang for my problems. If only there were the same amounts, all out problems would've been solved.
but what if it was the other way around and you where made out of antimatter? Would you have the opposite of your problems? 🤔
250 million years from now:
"and here we have the pre intergalactic ape, capable of life in zero gravity, but only for short durations. Finding this fella was tough. We had to look for a galaxy with star systems just old enough for them to have developed, with planets that could've supported such primitive life back then."
2:30 if they were the first, WTH were they looking above the water for?? What were those eyes worried about😮
Food
Not worried of anything just wanting food like berries but earlier
Probably food or smth
They were the first land vertebrates, massive carnivorous insects like bobcat sized scorpions and dragonflies with just shy of a meter long wingspans! So A LOT to feel anxious about haha
Thanks for another great lesson/video, Lindsay! Much love to you and the fur babies. ❤
This fish is going to make me fail college biology
Lindsay, you are arguably one of the best science communicators on the scene today, and by far the quirkiest and most unique. Fuckin love your channel, sister! Rock on!
0:10 so that IS the real fish😂😂
I know about this fish because the guy that discovered him retweeted a pick of a minecraft mod that depicted the fish, saying it was a joy to see
Really like these shorter deep dives into scientific discoveries!!
As a at-one-time science/ biology teacher, I greatly appreciate (in addition to pretty much everything in your videos) how you include/ convey the excitement of discovery & drama in the history of the science,
That's not easy to do (or even inow about without a bunch of personal research) in a classroom setting, and i know i sold my students short in a bunch of ways in the great struggle to just keep up with the required basics & finding decent labs to do & so on.
(It was ~15 years ago. it's a lot easier to find brilliant content like this now 😁)
Wow, what a tale of an absolute W. Great vid! Love the new studio btw, the bigger board is great, but as a bassist I do miss ogling your badass bass🥺
Neil Shubin wrote a book about it called “Your Inner Fish” and its epic and amazing and I recommend for anyone who wants an even more in depth explanation , mostly on the evolution on human hands but also the story of how Tiktaalik was found
I for one would absolutely love to spend my summer looking for fossils in the high arctic. I spent my days off in the arctic looking for fossils and crystals.
Come back to Minnesota, we've had like 3 days where it snowed this winter, and the snow was gone by next week.
My fav video so far. Love the new spot. And seems like your vibe is hella better also.
This would make quite a movie
Especially loved your delivery, well done !
Awesome video, but I’m a bit disappointed that the Antarctic expeditions weren’t called, “Neil and Ted’s Excellent Adventures”!
Also, kick ass Dog Years Skate Club shirt!
You honestly are my favourite UA-camr along with the octopus lady, and I want to be a type of marine biologist!:D
Octopus lady? Is that the channel name? I am not familiar but would like to be
@@kneeneart3208 That's the name and she's very cool.
I first learned of this in the Dover Trial documentary. How they found it blew my mind.
Thank you, I always look forward your videos keep up the good work
Neil Breen's done it! He's gotten his foot in the door!
Great of you to remind us that they existed for themselves, not to be a transitional creature in our evolution, good you keep us grounded!
As a fellow tuxedo cat ower I love him. And my childhood cat played fetch with bottle caps brought it back and everything.
I have to thank you, I recently had an opportunity to explain ecolution to creationist, couldn't have done that without your videos
you are such a gift to humanity
