Quote:Guppies in the wild have evolved over at least half-a-million years -- long enough for the males' coloration to have changed dramatically. Yet a characteristic orange patch on male guppies has remained remarkably stable, though it could have become redder or more yellow. Why has it stayed the same hue of orange over such a long period of time?
Because that's the color female guppies prefer.
