The Guardian's pictorial is titled Masters of Disguise. But, lest anyone imagine any intelligence behind all this (— what? no! no, of course not!), the text helpfully explains that "natural selection has crafted some remarkable lookalikes."
Now, turn that over in your mind. "Natural selection," a mindless, impersonal, purposeless process.
"Crafted," a purposeful, intelligent, personally-guided procedure.
But it's only scientistic... er, scientific... to believe that these things Just Happened.
