A ratchet, in its mechanical form, is a device that permits motion in one direction while preventing it in the other.
a cogged wheel with angled teeth that a spring-loaded paw catches when you try to turn it back.
The functional ratchet works by the same logic, but the teeth are made of survival pressure rather than metal.
Here is how it operates.
Mutations arise constantly in living populations.
Errors and variations in the copying of genetic information, not all of which are as random as they might appear.
Most are neutral or harmful, but occasionally a mutation creates a new capacity that helps an organism out-compete its peers.
When that happens, the organisms carrying the mutation persist and reproduce more effectively than those without it.
Over generations, the new capacity spreads through the population, and once it is spread widely enough, losing it becomes nearly fatal because the organism's survival now depends on it.
A winning function, once established, becomes load-bearing.
The survival loop that depends on it cannot easily reorganize around its absence.
And so the function persists, not because nature has a plan, not because complexity is the goal, but because the pressure of competition makes retreat almost always fatal.
