This is kinda how evolution works. Random mutations in genes. The good mutations carry on through breeding.

Bearing in mind that when you’re talking about evolution, “survives long enough to breed” is the only criterion for “good” that matters.

Pigeons literally do not care what the partner looks like as long as they have recognisable pigeon features. Scientists have tested this by making horrible pigeon monstrosities and showing pictures to normal pigeons. They literally only cared about the fact that still pictures can't do the dance.
