"A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over, beginning with a working simple system."

This describes biological evolution well too.

However, I wonder how this works for physical things, how does one create a simple version of a train or bridge? Some things have a complexity floor.

How did the "simpler" physical laws looked before nature arrived at the current ones?

(That's a half serous question, of course.)
