A puddle full of chemicals
Was baking in the sun
When some combined a different way
And new life was begun
It replicated, once or twice
Till now there were a bunch—
They chanced on an amoeba, though,
Which ate them all for lunch.
Some inorganic molecules
Embedded in some clay
Began a new reaction, and
They sprang to life one day
They started reproducing
Was it brand new life? Well, yup…
Till they found a paramecium
Which promptly ate them up.
It is said, abiogenesis
Is really very rare
Perhaps it happens all the time
Without observers there
The only time we’ll know for sure
That brand-new life begins…
Is when it meets established forms
But this time, new life wins.
I don’t know where this one came from, but it took all of 10 minutes to write itself. A new, successful mutation, I suppose.
Are there any biologists reading this who can tell me if my thinking is off? It seems to me that the various abiogenesis experiments (think Miller-Urey) have one fatal flaw–they are miniscule in comparison to the real world. In the real world, we have the same, or similar, experiments happening all the time. There are theories of life beginning in tidal pools, or in a clay substrate, or in geysers or mudpots, or steam vents… well, why not all of the above, and more? The world is a big place; unlikely events happen all the time, in large enough populations. Of course, any abiogenesis event that happens now has a serious disadvantage: the parking spot is already taken. And so, of course we don’t see abiogenesis happening in the world around us; something else has already snacked on it–probably a bacterium.
But (because time is patient), isn’t it possible that one of these times, Life 2.0 will disagree with that bacterium. Then eat it. And its cousins. And establish a toehold on the planet. Could already be pockets of Life 2.0 v1-vn in places we have not yet looked. (Or maybe not; this is idle speculation.) It took a staggeringly long time for our own ancestors to get beyond that stage, so there is no reason to suspect we will be alive to answer this question… but rare things do happen. Not just a mutation of a current life form, but something altogether different. Wouldn’t that be astonishing? Wouldn’t that just scare you to death?
I gotta work on the screenplay.
