Ever since he was a graduate student, Neil Shubin has been obsessed with finding fossils of the creature that marked the transition from fish to land dwelling animals. He explains how he scoured maps to find rocks of the right age and type that were accessible at the earth’s surface. This led him to the Canadian arctic where, in 2004, Shubin and his colleagues found Tiktaalik, a fossil of a creature with features found in both fish and tetrapods. Tiktaalik was the link between fish and land animals.
Speaker Biography:
Dr. Neil Shubin is an author and Professor in the Department of Organismal Biology and Anatomy and the Committee on Evolutionary Biology at the University of Chicago. Shubin’s research focuses on understanding the evolutionary origins of new anatomical features such as limbs. Shubin is well known for his discovery of Tiktaalik roseae,the 375 million year old fossil link between fish and tetrapods. Shubin is an elected member of the National Academy of Science, the American Academy of Arts and Sciences and the American Association for the Advancement of Science. - Наука та технологія
There's only one youtube channel linking to this video, that we know of.
We are all connected. Period. I feel bad for all these creatures who are no more with us, but who unknowingly have given us so much of knowledge and last but not the least, a very big thanks to all you good people who do the research and digging and all that to uncover the truth...to put that missing piece.
I'm reading Neil Shubin's book, "Your Inner Fish," that explains the same information in much greater detail. Excellent book! I'm a big fan of tetrapods.
There's a great video too, the first of three episodes. "Your Inner Fish"
What a nerdy title! ;)
His energy is super infectious
If you are here for an assignment, click ... next to the like button and there's a transcript. watch the video then read it! Good luck 😊
Goodness, how exciting! _Australopithecus afarensis, Archaeopteryx lithographica,_ and _Tiktaalik roseae_ are my three all-time favorite fossil finds.
A. afarensis and archeopteryx are debunk already as transitional species.
@@harveydayaday4753 *"A. afarensis and archeopteryx are debunk already as transitional species."* Says who? Someone like yourself whose education in Biology (and also apparently, English) peaked in junior high? The only thing 'debunked' here is the assumption you know what you're talking about.
Perhaps you can enlighten us with other ignorant opinions on things you are clearly uninformed on. What's your take on the latest financial announcement made by the Fed? Do you think the landing system of the latest Mars rover is efficient? What about the efficacy of _fluvastatin_ compared to other HMG Coenzyme A reductase inhibitors?
Fool.
@@harveydayaday4753 I smell a young earth creationist.
@@waitslegacyblitz728 These intellectual maggots infest every corner of the internet. Thanks GAWD they are so dumb ;)
Steve is an MVP! Steve found Tiktaalik in Canadian arctic, and earlier he found toes and leg bones in Pennsylvania when Neil was gone to the other expedition ;)
This is a great video! So interesting to see how multiple disciplines of science were used to locate the fossil!
I think he means to say the link between fish and land vertebrates. There are invertebrates that live on land but they are not descended of fish like how tetrapods are.
ive met him nicest guy in the world and his lab is awesome
Wow such a great video for understanding the transition of life through the fossil record, addressing the questions I had for if we had tangible evidence of the "missing link" in our fossil records.
Great presentation!
Thak you, Tiktaalik!
Que interesante descubrimiento del Tiktaalik en un lugar remoto del planeta
This discovery is undoubtedly one of the strongest verifications of the entire scientific process in history. I am glad I now know the name of one of the people who made it possible.
Very entertaining and informative
Read his book recently, brilliant read
i love the video
How does a video that says it premiered 2 hours ago have comments from months ago?
That's an incredible quest to discover something half-something hlf something
Can't believe George Lucas teaches me about my grandpa
Very informative and entertaining.
Very interesting and entertaining. Thank you!
Great job sir finally I know where my whole arm bones come from!! An important detail to the big picture.
True, even whales have such bone structures in their arms!
Who's the genius that wrote "centrography" when he said stratigraphy?
great
School sucks I needed the last five minutes -_-
bruh lool same.
It sucks, but if you skip it, you might become the next generation of flat-earthers ;)
Good day everyone, Lindsay Nicole send me! She sais your videos are good. lets see.
brabo
Important discovery and one of the proofs of evolution. Many maroons claim theory of evolution had no predictive capabilities, which is not true, but this find is perhaps the most definitive prof it has! Stay curious! ;)

Cool a giant salamander found 20 million years after tetra pod footprints.
neither of these things you said were correct lmao
Thank you, titaalik the almighty
look, i'm still surprised plants are only 200'ish million years old.
+Paulo H me too
Paulo H well, "plants" are that old but organisms that used photosynthesis but weren't completely "plants" began long before that.
1:10 says "three things" but uses two fingers....but still good video of course.
Laura Reyes wak yes
Places with naked bedrock?...MISSOURI
Do you mean bedrock of stupidity? ;) It is one of the states infested by Mormons, isn't it?
So where is the PARTIALLY developed neck..part way between a fully developed neck and NO neck?
Tiktaalik has greater mobility of what is homologous to our cervical vertebrae, and later genera such as ichthyostega and acanthostega have even more prominent basal necks.
We are salamanders
Reconstruct? If you can illustrate..lt MUST be true, right?
Well, no, we don’t just draw the transitional features on them, the fossil has that, they are there, sorry.
For more details info you have to look into research papers. For obvious reasons popular-science videos can not be comprehensive.
I've got two engineering degrees and probably that is why I think "the informational/factual density" of this video is very low. It's like an essay of a student who only knows reading list but read none of the books.
"... Neil Shubin has been obsessed with finding fossils of the creature that marked the transition from fish to land dwelling animals ..." not a good indication of impartial approach, critical thinking, intellectual rigor. Evolution is presupposed, facts are interpreted to fit this and finally, conclusions are used to support theory of evolution. Nice circular pattern used for brain-dead viewers.
Niel Shubin have articles on Titaalik rosae, he explained it very well for everyone to understand. Anyway, this is a part of evolutionary lectures ... If you read some articles in Evolutionary Biology then you will appreciate this one
One more thing this is also part of comparative Vertebrate anatomy. See the book of Kardong (2012)
Luzt it’s for the uninitiated, if you already know this, it’s not for you.
Luzt and no it’s not circular reasoning. It’s more like developing the uniform field theory. We know where we are, we know where we came from, we have a theory. We look in and where we hope to support our theory. They found something, of that correct age and development that supports the existing theory.
Incidental, circular reasoning is used every day in mathematics as well as tautology. A geometric proof is pure circular reasoning.
And my hero, the viewers are not the ones who are “brain dead,”evolution is not a presupposed theory, it is now accepted as scientific fact, being supported both by the fossil record and actual observation. I don’t mean to be unkind, but there are 400 million years worth of well preserved fossils showing the evolution of various species connected by anatomical similarity. Further, more recent fossils or preserved remains from the Pleistocene and Holocene have had recoverable DNA which has left a chemical and genetic record of more recent descent and evolution. I have great respect for engineers, coming from a long line of engineers, but it was the engineers who said powered heavier than air flight was impossible, that iron ships couldn’t float, and that the patent office should be shut down since everything useful had already been invented. It was also engineers who proved all those assertions wrong. Be the second kind of engineer; the kind that aren’t brain dead.
This was debunked in 2010. Why are you still teaching it as science?
It's a giant salamander! And they still exist! Google it and see for yourself!!! 😁😁
You keep telling that lie. But its not a salamander. Google REAL science yourself.
