- As an evolutionary biochemist at University College London, Nick Lane explores the deep mystery of how life evolved on Earth. His hypothesis that life arose through primitive metabolic reactions in deep-sea hydrothermal vents illuminates the outsized role that energy may have played in shaping evolution.

Quanta I love your videos!! Can you please post more of them? Like waaaay more. I could EASILY down 3-5 Quanta Magazine videos a week, they’re so good!
that doesnt really sound like downing anything
Seven minutes of Nick Lane? How can you do just seven minutes? This is like giving someone a sip of wine and telling them to get lost!
Excellent. Now the hour-long version.
Thank you so much for creating this Quanta. This is so well done and awe-inspriing.
His books are amazing. My favorite was oxygen.
6:11 moments like these are why we love science.
Love Nick Lane his books are really fantastic & such a down to earth gent.
Another Amazing video from this channel!
OUTSTANDING -- have all his books !!
Everytime I watch these videos I kick myself for having majored in Physics and not BioPhysics. Thank you, Nick Lane. Yes, I still miss Stephan J. Gould as well.
that's really remarkable to think about life on earth, we don't even know how many mysteries are waiting for us.
The deep oceans is where it's at, so many undiscovered animals down there
@@HShango no it's more like a desert
great video and thank you for accompanying it with beautiful music.
Edit: does anybody knows the outro music?

Amazing!
Great book 📕, 🤗🤗
I JUST bought Transformer today. Haha, what a treat. Nick Lane is amazing.
Que bonito video y profundos pensamientos. Energía e información

I appreciate the German Autobahn scene at 5:48 :D
More quantum physics please Quanta!
I watched this video multiple times in the span of a few hours and i find it absolutely fascinating.I have always had some sort of grudge against biology because that always meant for the people around me that i am to become a doctor,but this video made me interested in biology in a whole new sense.there is however an idea that i can’t quite grasp and that is when mr. Lane says”if we shrink ourselves to the size a molecule that is equivalent to a bolt of lightning”.can someone please recommend me further reading into this matter?
What I imagined is that the energy output and the energy that you would experience is like that of a lightning strike, mainly if your that small the amount of energy you would need to cross past the cell membrane would have to be larger than the gap that exists bettwen how much force you output into energy relative to how much lightning makes? I dont know I tried XD
It's to do with the voltage across the membrane. measured in volts per metre, essentially. A huge electric gradient that powers reactions. His book transformer is more explicit on that and a bloody god read too!
Phase transition in structure could explain the long gaps
"At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion."
That was great
How do we know it happened just once? What tells us that in the primordial puddles there wasn't multiple lineages figuring out cell walls?
It's an assumption based on something called maximum parsimony - all of the lineages share enough in common that they're more likely to have been derived a single time, and diversified from there. But at the end of the day that's only an informed hypothesis - it breaks down if you assume that there's only "one way to do it". In that case, it's entirely possible that it could have arisen multiple times.
@@chinobambino5252 assuming there are multiple ways to do it, but each requires a number of steps in sequence which takes significant time to occur, you would only expect one to be seen, because it just eats any competition before it can bootstrap.
Because all present life has the same genetic code for example and we know there are a lots of other possible, someone created bacteria with alternative genetic codes even with 4 and not 3 bases. So it’s very likely that alla present life originated from one. But yea that’s not the same of single origin maybe there were multiple origin of lifes but the other were then outcompeted by the ancestor of LUCA
If he was my teacher back on school, maybe I can fall in love with science
although the specific design and position is extremely important and specific, you could also quantify that in energy terms. It just not practical. Hence his explanation is good and very contextualized. I'm happy to see this kind of thought in academia.
i like this guy.
For those who dont see the argument, go watch his RI talk! He goes through the theory in detail
where can it be found thanks (eg I dunno what RI stands for)
Thanks

If your IQ is below 90 then I can see how this seems profound.
No, complex cells happened at least twice, once in the Francian shale at about 2bya, and later when it happened again and stayed with us.
Great common sense video. Kudos.
The video is filled with "did you know that life is complex?", which duh, but I'm here about the topic in the title.
It's an interesting video with a poor title imo
i have troubles understanding evolución.... do stocastic chemical procesos Just explain it?... were vents responsable for the síntesis of nucleotides phospholipids proteínas etc? how do vents explain the organización amongst them, how do they explain th flow of información, were proteínas first or nucleotides? did cytochromes and the hidrógeno pumps in mytochondria randomly appear ? is probabillity enough to explain all these processes?
@Kraig StClair Thank you. I brought it up because he talked about the primordial soup and then went on and talk about how he hypothesizes vents were more probably were life would have found its origin.
i can only assume nick's publisher forces this on him. only catch sight of him when he's a new book to peddle.
which means i've likely a new book to buy.
Phenomenal video. Great perspective regarding cells and a reminder for us to not consider genes the end all/be all of evolution.
Thus guy about to eliminate the lengthiest chapter if class 12th ✌🏻
Life started not in a soup, but in a pie.
I sure am baked.
Thank you, ever so for explaining the structure

Now that sounds like u are confusing magic with energy. Never seen energy being unnoticed in the west. But I have seen so much B's about energy

The primordial cell
This was a reverie, not an argument or even a statement of hypothesis, with production values taking the place of any sort of coherent thesis other than "wouldn't it be neat if..."
And it isn't intended to be, it is intended as a primer to get you intrigued. Read his books (especialy the latest two are fantastic) if you want the simple version of his arguments, and the peer reviewed articles of his research group if you want the detail
I have to begrudgingly agree that this is a disappointing video inasmuch as it does very little to deliver on the title, "Exploring the Deep Mystery of Life's Origins." At a certain point early on as I was watching the video, however, I realized that this was just a biographical vignette. It is not a disappointing video if it is understood simply as a brief statement of a scientist's motivation for pursuing his passions. I may not agree with his particular point of view on everything he is saying, but it is not important whether I agree or not for me to sympathize with his excitement for the object of his studies. Finally, all I have to take issue with is the title of the video; it is not an honest title, or in other words it is 'clickbait'. But I can forgive the title because I'm glad there are scientists with passion for their professions.
Well looks like learning mitochondria was the powerhouse of the cell all those years back is useful😂
@Fk Yu yess learnt it in school... Cell biology in general is quite interesting
The outer core of the earth is the confirmation of growth both for life and the body human which is why God said cursed is the ground and from thy brow will though till the earth
Jesus, Nick Lane explains biochemistry with the same contagious clarity and passion as Brian Cox explains about quarks and the expansion of the Universe. Thank you for this brilliant video
"it has nothing to do with genes"...."another cell got inside and that changes the topology.." yeah. Because of the genes that allowed those cells to merge, man.
If I'm not wrong, the way mitochondria works is pretty weird. Our DNA doesn't carry instructions to create mitochondria. They kinda reproduce separately and don't have much to do with our genes. So in that sense, he makes a fair point. Evolution is not only characterized by the steady mutation of genes but also by freak events like the one that led to mitochondria.
It is much more complex argument than a 2 minute video allows. Of course genes are important, Lane knows that and at length explains that in several books and article. They are just not the only important parts for the origin and evolution of life as some science popularisers have implied in the past.
@@bartpander If time is the issue then maybe he shouldn't use precious seconds to say stupid and categorical things as "nothing" "never" "always" "forever". If it has something to do with genes, then say ..something, but not all. Why not say "also" or "a big part of" "most of"?
If he's so smart, he should know how to use words like a responible scientist, not like one looking for glory.
@@jezer8325 And didn't the "event" occurr because genes allowed it? Some mutation somewhere made it possible for the big cell to not digest the small cell, and even allow simbiosys. It has something to do with genes. Not all.. maybe not even 90%, but something. Certainly not "nothing". It's the categorical nature of the word that bothers me, not that he might not be right about his discovery. I don't even know what he discovered, I didn't listen after that "never".
Spot on
i like primordial soup.
The primordial soup - this guy ate it up with a spoon
You shouldn't confuse "primordial soup" with Quantum Soup
I was expecting some science and to see some math, and all this video had were a bunch of adjectives and ethereal music.
It seems to be very basic video intended to inspire curiosity. A more meticulous analysis is likely not appropriate for such a short video. It's a good video
It is called a primer.
Maybe its because origin of life research is still so highly theoretical with little hard science
Someone has a recommendation for some more into depth video with more organic chemistry, math etc..
@@nicholasfevelo3041 all of it is hard science. They just don't have the right theory.
When one life form started eating another life form?
Remember that one time that bacteria designed, engineered and manufactured the laptops and smartphones we're all watching this video on?
Astonishing knowledge and evidence about the paths of life! Something like this it's an open door to leave behind all tribalism and belief systems that some of us still carry nowadays. 👌👏
It’s silly to think humans can leave behind tribalism when that’s how humans are built to function. There are just new tribes these days, the processes that lead to tribal behaviour are still inside us.
@@scrumptious9673 Tribalism it was the defensive behaviour to preserve our ancestors communitys in the lack of comprehensive understanding about what was a threat or not. Evolution allows us to developed empathy so tribalism in modern society's are completely outdated and anachronistic in nowadays. Nevertheless for some people most with personality disorders this is hard to take and convenient to legitimize their own behaviours.
The video is as basic as they come.
Tribalism is an evolutionary trait as is assigning agency to unknown events.
Aron Ra is good if you want to go next level.
I missing the link the link between the title and the content, cause everything he tells us is already known since long time... so no new revelations, but old knowledge made up as "super new". We ahve so many aspects shaping evolution, from pure luck, to exactely given boundaries, from availablity of molecules, but also prey and enemies... and if another "life" would eveolve from dead mater at all, it would be probably eaten still today... but no deep mystery resolved....
What, exactly, did you expect? The answer to the question what the question is that has the answer 42? ;-)
Still no answer

I think u meant, 'how we THINK life began'
Evolution has been brought to you by the Second Law of Thermal Dynamics.
The worst thing you can do as a scientist is speak in absolutes. This immediately makes me skeptical, especially when considering the already present disagreement in the scientific community
What disagreement?
Yeah, it indicates this guy is a seeker of publicity, not a seeker of truth.
Because of god correct?
Scientific FACTS do not set out to destroy stories in early book containing magical being, it does it coincidentally.
How do we know life is not arising from chemical evolution right now on earth?
I think the argument goes like this: everywhere on the planet where life could spontaneously arise, life is already established. This established life makes it very unlikely that the conditions (e.g. by eating the nescesary chemicals) for new abiogenisis occur for long enough for new life to get established. And even if it would get started, it would still be incredible slow and primitive compared to the 4 billion year old lot and thus likely eaten.
@@bartpander this
It's a paradox
@Kraig StClair All live ever sampled, including those at many hydrothermal vents seems to be of the type that has been around for 3.8 billion years. It should be relatively easy to distinguish truly independently abiogenisesed live from the established one since it would not point to LUCA as its ancestor in phylogenetic analysis. As far as I am aware that has never been found and it falls within my field of expertice (molecular Microbiology) so it is be unlikely I'd miss such news.
The jingly music in the background is VERY annoying.
the mitochondria is the powerhouse of the cell
I used to think life like plants and animals were abundant in the universe. But I don’t think so anymore. That the earth is one off.
Yup
I really enjoy the information provided, however, the repetitive background music is annoying and detracts from the information and knowledge being provided. I like music but not that which drowns out the person speaking. Thanks for being here.
I don’t see the point of this video. The title promises some kind of revelation, but it’s just dreamy talk about what we haven’t learned yet. The fact that energy plays a role seems obvious.
Just stick to Tik Tok videos kid.
How does the title promise some kind of revelation? It literally just says how it didn’t start. Is your beef with theoretical science itself or the fact that your expectations were let down
Exactly. He’s just hashing over very basic concepts on the origins of life. And for him to say that life only originated once is a careless argument over something that we have little to no empirical data.
He talks about how he doesn’t like the concept of “primordial soup” but then talks about how life likely started with the help of hydrothermal vents. My guy, that is what we mean by “primordial soup”. You have organic molecules that come together to form single celled organisms.
I really don’t understand the point of this video either. There’s little to no useful information in it. Seems to be a huge waste of time to make.

Next topic Quantum computer language or power acceptor devices.
What is dark matter?????
A theory of anything explaining things as outcome of "accidents" that no one witnessed is very disappointing. I find much more intersting a proposal like Stuart Kauffman's At home in the universe.
What accidents are those? Please be precise now. ;-)
If this question is given a satisfactory answer or whatever theory putted forward is proven then this shall mark a singularity on thought especially in how special we think we are in the spiritual or religious sense of the word ; hope to be around when it happens as it is obvious that it's not question of if but when.
Funny of you to think that people would actually accept facts.
W science.
This is not how life began
Rigid or soft cell walls, Chloroplasts. Multicellular? Differentiation? A few more minor charms. But that's the evolutionary minor leagues. (i.e. the difference between say plants, fungi and animals). The really, really major changes are all like how mitochondria and a few other organelles came about. And mostly by some more specialised cell finding a home in another type of cells. At this level of evolution multicellular organisms are likely dead ends. Naturally speaking. For it will is far more likely that the next really big thing will come from single celled organisms. Which may then in turn evolve into being more complex (evolutionarily rich?) than the complex life as we know it today.
Speculatively as examples: Why shouldn't there one day be cells with something like graphene cellular walls, powered by maybe micro fusion, storing genetic information in super durable crystals with vast redundancy and precision? Or single celled life complex enough to themselves be conscious? There's time. Far more than "we" likely have on this little planet.
He does not really understand what the 'primordial soup' is all about. Nobody said that life started with that soup. What was said is that life arose from that soup, that soup is a 'condition' for life to emerge.
He’s literally an expert in the field of abiogenesis, I think he understands it
Well I think he does understand but doesn't agree. He always claims the soup is too dilute. I think even dilute 'soup' might turn out to have some importance considering how modern organisms can use nutrients from very dilute sources.
@@bartpander here comes Bart to police the comment section
@@bartpander The importance if the soup seems established. The question is: from which moment we can speak about biological chemistry (instead of chemistry)?
@@graysonaudette3525 As far as the 'origin of life' is concerned, being an 'expert' does not mean much. We are still hypothesizing...
Well obviously the long gaps can be explained by those are the times when the monolith arrived.
Enchanting, however, he completely side steps the molecular process at the cellular level which are incomprehensible without some form of agency. This is why an approach cemented to blind chemistry will always fail. It closes the door to new possibilities and new paths to understanding.
Have you read his books? I find he sidesteps nothing, and explains things at a molecular/chemistry level, which is quite refreshing for a books aimed at non-scientists. He dumbs nothing down more than necessary. On the other hand, if you didn't understand high school chemistry, you should probably skip them.
A very long time ago we had a visitor that died from our chemistry
Blimey! Why have I not heard of Nick Lane before? Explain all life on Earth in 7 minutes...Go! OK, there you go, simple succinct, no waffle or Jargon (ok, I'll give you mitochondria) - some one who knows what they're talking about. Thank you.
Read or (listen to) his books. They are great.
@@bartpander Thanks, just ordered 'Transformer'. 🖖
bro life started before there was oxygen on the planet? thats crazy.
Bacteria (yes) that's true life started spontaneously on earth
As ALL the free oxygen in the air was released by living organisms... Life HAD to have started on Earth before free oxygen. The oxygen has always been here but locked up with two atoms of hydrogen in water.
Since O2, gaseous oxygen is mostly made by living things, that was obvious for a century.
What's up with the fucking background music?
All this complex biology evolution cells and all i feel is pain
Indians, for thousands of years have acknowledged this very thing, albeit with a twist, that the divine lives in all. Hence, the worship of animals, plants and rivers and mountains. Despite the entropy of rivers and mountains decreasing, the fact that all life is just entropy, is the core belief of Vedic India, hence the emphasis on meditation.
Oh yes, the indians know it all, should've known too
Humanity is an instrument after all
Hummmmm....spontaneously

In a nutshell: plants and living creatures have same origin and energy drives the evolution of life.
Nice episode. But anyone who thinks it is "amazing" that basic building blocks can give rise to incredible diversity hasn't played much with lego nor explored binary strings and quantum physics, nor looked at Ramsey Theory, I suspect. Combinatorics kicks ass.
That doesn't make it not amazing.

First ever!
This is probably the worst video that quanta has put out - and it's really damaged your reputation.
It's full of suppositions, leaps of faith, and vague language
Life on earth could have arisen more than once. Our form of life was the one that survived.
In my experience with people at UCL, these "grand thinkers" are just hollow headed scheisters who know how to do sensationalised public engagement and are good at grantsmanship.
I'm very disappointed in your editorial team for publishing this. Do better.
Agreed.
Completely agree. And his tone throughout the video is just so overbearing.
U can go back to ur LGBT videos now
This is the same type of language that any scholarly journal of evolutionary biology uses, I don't really understand the outrage. The amount of empirical evidence we have to make any educated assumptions about the origins of life are miniscule so any exercise in attempting to piece this together is largely an act of creative storytelling with pieces of circumstantial data thrown in.
Thank you
