The Train Runs Over the Camel

As if to be some kind of test,
Born out of the boredom of who's better than the rest.
This time they wouldn't measure the pointless small details,
The only thing that mattered was if the "you" prevailed.
Maybe it's just some coincidence that natural selection always works the best,
What if they didn't count the molecules that failed,
And the only thing that mattered were the pieces that prevailed
