Cool Ive read about this for years but its cool to see someone try to animate in way that easy to describe towards those who lack context. Thank you.

This video has changed my life. I already signed up for chemistry and micro and cellular bio. thank you.

Okay, STOP! Yes you, stop and read. Before commenting that this is 'unscientific', (if you were going to), quickly search for the YouTube channel Stated Clearly, where they go in depth into this topic, and well, states it clearly. I recommend watching the videos in order, or watching their playlists.

Thank you and carry on :)

The simplest of beginnings. A single, self-replicating RNA molecule. What?! What about that is simple?

i much preferred Stated Clearly's version of this explanation because saying that " the strongest code could survive" makes no sense if you don't explain the processes that create the competition in the first place. As usual, a pretty video but not very informative.

Further important points to mention: even though the longer term store of genetic plans is DNA, this is still converted to RNA today as the messenger that is decoded into the required protein; secondly most protein molecular machines consist of a large percentage of folded RNA strands, indeed the proteins involved often only add to the efficiency of the machines which function albeit slowly solely as folded RNA.

I appreciate the honesty of saying "we don't know". The complexity of the first rna driven first cell is not "simple". To think it just happened by uncontrolled, random, natural(unthinking) processes requires evidence it could happen. We don't have that

Thanks  so much for the easy to understand science lesson!!

Very nice! Easy to understand and very good animations :)

so RNA is conscious? how does it make decisions? how does it move? how does it evolve and what is it competing for? i find it hard to understand how RNA became protein

wow I wish my college slides and clasess were like this, this is so fun to watch and take notes lol why not make school fun? =(

This needs an update as we have way more information about this now.
Seems like RNA couldnt self replicate yet.
But to replicate RNA used molds and the building blocks kinda formed within those molds
This has been tested and it works

It is an amazing break through within science and abiogenesys and I would love to see a video about this!!!

Its weird to think that rna and species are basically a game of war of tanks where they try out different designs and see which can last

Very well broken down for the layman. Glad I watched.

It takes a great deal of intelligence to understand that life began by accident.

Good overview. Best hypothesis I've seen yet. Yeah, that's right--RNA can be both an information store and a nanomachine. It makes sense that it came first.

From so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved

The end game for the most suited (adapted) to the environment is to have the highest chance/probability of Survival (ie. Survival of the fittest), The ones that are not, will not survive, like the early Forms of life Charnia.

This does not explain why or how any RNA molecule began replicating. If anyone knows an answer to that, I will send them karma. Replicating RNA would be the beginning of evolution, once you have replication you have competition. But I just can't fathom the very beginning. What reason would cause any strand to make a copy? By what mechanism?

So what do you guys think about Dr James Tour?
