- Astrophysicist Dr. Paul Sutter returns to Ars Technica to once again take us to the Edge Of Knowledge, this time unraveling the origins of life on Earth. Dr Sutter is joined by molecular and cell biology expert Dr. John Timmer to discuss what we know, what we don’t, and how we’re trying to find out more.

Rudyard Kipling would be proud of you guys. A fantastic Just So story!
It’s often useful to describe fire when explaining life, and how it has some similarities like respiration, metabolism, and replication but fails the test. Also you should have mentioned evaporating pools. Right now we think that the process of evaporating a pool of water with organic molecules triggers the formation of membranes like cell walls and more complex molecules.

step 1 - Spell Spaceship
step 2 - then Boom
step 3 - fly to space
just like that😆
Such an interesting topic and well made video. Thanks Ars Technica! You guys are awesome.
This was fantastic, I had learned about a lot of this in my college geology classes, but there have been so many developments in the last twenty years that I was unaware of.
Such an interesting topic, great video guys!
really well made video! very informative
Great presentation.... very thought provoking!
yeah, too bad terraplanist dont think hehe
i love these videos
Very good Paul ☺
can we have some statistical value for the probability of your theory?
The legendary Freeman Dyson wrote an interesting book called Origins of Life in which he argues for the metabolism first hypothesis for life’s origin. He proposes a mathematical “toy model” for how this may have worked, but that part was over my head. I think physicists can make valuable contributions to biology because they have the conceptual tools to help to mathematically formalize messy biology. Systems biology is the future of biology
l always thought the answer was gravity
Love the episode. Not a fan of the over-head camera.
We know this happened, we just don’t how. AKA we just made it up and want you to believe it.
It didn't go from dead to alive, there has to be life first before it can be dead.
I still can’t believe that everything in the known universe was inside something smaller than the head of a pin. I just recently moved house and let me tell you, only so much went into a 📦
You don't believe in sayaance?!
It is a typical rookie mistake to extrapolate a cardboard box to the Planck epoch. The temperature was so high, particles didn't even exist. The fundamental forces were also unified and acted as one. Completely different realm!
Not true biologically
thank god for creating this world
thank you for explaining how
you're welcome
thank the Force for creating this world
The only available answer to the question is that abiogenesis is impossible, the RNA World isn't a thing, metabolism without reproduction is a dead end, and reproduction without metabolism is just dead.
Argument from personal incredulity. Also objectively false, since impossible is not the only available answer to abiogenesis.
@@pavel9652 yes, it is. This is not a case of an argument from incredulity. It is possible to know precisely what abiotic chemistry in all available environments on the sterile Earth and these chemical reactions do not produce any molecule essential to a living cell within any time relevant to the lifespan of a bacterium.
@@sentientflower7891 I already demonstrated your statement is false on the logical ground. I am here to learn, not to shoehorn my thinking into a bronze age book, if this is what you are referring to. It is not possible to demonstrate it is impossible. You can't produce ALL available environments with 100% confidence. Nothing is 100% certain. We detected organic molecules including amino acids in molecular clouds in interstellar space and DNA nucleobases in meteorites.
I just responded, but the comment is visible only to me. Ridicules. We detected organic molecules including amino acids in molecular clouds in interstellar space and DNA nucleobases in meteorites.
4.5 billion years lol how you know this is stubbed thing people need to open theirs eyes
Thanks to the power of evidence, baby.
This is just crazy religious talk. This guy believes his ancestor could be a beach hit by lightning.
Unless God came down and wove our DNA together by hand, life has to start somewhere
lol
He has the evidence showing organic molecules spontaneously happen this way and also in space. On the other hand, you believe without any evidence in invisible wizard who did a little hocus-pocus and disappeared into background noise.
