One of the most profound questions we will ever ask ourselves...  How did life begin?  How did everything I know come to be?   My simple answer is thought.   It was the late Carl Sagan that proved the Nuetron can transform into mass and space.  It was advanced neural sciences that taught us, thought, is in the Nuetron.  The two, also known as the Electron and Proton go hand in hand.  Thus the evolution of life began.  The mere suggestion that even the smallest of particles are life forms is humbling, yet there is no reason to doubt it and as science progresses a fact we must accept.

Does it need to respire? Some of the most rigorous watertight arguments for life i have seen involved being inclusive (viruses etc...) but it was basically any system, which as a whole, acts to reduce or reverse entropy (locally).

 

Now, as entropy is a term thrown around alot. And i cannot give a briliant definition, i will say that what i do know, is that a highly ordered state has less entropy than a disorderly state (a sand dune is much more likely to form at random than a sand castle). If you look at a cell, it has processes which actively defy events that should happen such as diffusion. Cells have carrier proteins in them which pump in minerals and ions against concentration gradients. Thus, it makes the disorderly state of equal, random distribution, more orderly.

 

Equally, to look at a virus, it's protein shell acts to prevent the "diffusion" (for lack of a better word) of its internal component parts (the RNA). And maintain it's highly ordered structure.

 

Any self-replicating molecule (included in this definition) also does this. Because a molecule that is so complex as to replicate itself, requires a unique, and exact order, although it may arise from random events, it's replication is not random, and so, by placing its replicated molecule into an order, from its component molecules, requires it to hault the increase of entropy (locally).

 

This does not defy thermodynamics, all these bond forming processes are exothermic, and so add energy to the surroundings, increasing the entropy of the entire unverse. But locally is what matters.

 

Sorry, if my definitions are a little off, but hopefully the argument holds, nonetheless.

We seem to be discussing a topic that is as much Philosophy as it is science. Kurzgesagt have a brilliant video on the matter, which really makes you think what is and isn't life!

In my opinion it's very difficult given the arguments presented in the video above. I might just leave this and concentrate on physics- leaving this sort of question to those who study Philosophy and biology to a much higher level than me!

Well, physics was once called natural philosophy... 😉
