Life from Nonlife
This has been around for about six years now. It would require additional investigation to validate some of these claims, but it’s certainly the most intriguing theory for original abiogenesis upon planet earth. I always wondered -or thought life, or proto-life, began in this fashion.

Can somebody give me the TL;DW version of this?

RE: Life from Nonlife
The idea has been around for a lot more than a few years.
They have run long lasting experiments where they emulate an environment that would have been around in the primordial earth.
The Miller -Urey experiment.
It doesn't produce life but it does show that in those conditions naturally produce amino acids.
That is to say that in the conditions of early earth the natural compounds present naturally organize themselves into amino acids.
It's a first step.
https://en.wikipedia.org/wiki/Miller%E2%...experiment

After that it's not far to "life like" substances like Prions.
Those are what cause mad cow disease. They are pure proteins and not technically life but they do reproduce in a very odd way.

This video centers on the Protocell theory.
It's interesting in the same way as the Miller Urey "soup" idea.
It's cool how in the right conditions inorganic compounds form all this goo that is pretty close to life.

Currently the most accepted theory for abiogenesis or more specifically the first life that is related to the current DNA base life is the RNA model.
I actually think that it won't be long before they can produce RNA based life in the lab from pure chemicals in the right conditions.

There have been some recent breakthroughs.

He is deformed, crooked, old, and sere,
Ill-fac’d, worse bodied, shapeless every where;
Vicious, ungentle, foolish, blunt, unkind,
Stigmatical in making, worse in mind.

I think that's been the most interesting Ted talk I've seen yet. Thanks.

RE: Life from Nonlife
The videos of the moving "cells" and his descriptions of it looking like something akin to intent reminded me of the Hieder and Simmel video. It seemed like he was overreaching in a lot of the descriptions of what was going on.

Agreed. So I gave it a 'like' to show my appreciation. Wink

Reminded me of this...
