Sure, ultraviolet photoreceptors are cool. You know what would be cooler? What if birds, and their dinosaur ancestors, had evolved infrared phototransmitters that can lase? The world would be a different place. Imagine how upon hearing the distinctive call of the Red-Eyed Vireo animals and people would scramble for cover lest they become its next charred meal. On the other hand, self-roasting chickens would be a godsend for the industry.
Thank goodness birds are not real or this might have been a thing.
