On the list of scientific tools that help us understand health, evolution or the environment, the Trinidadian guppy doesn't often come to mind. The fish are more often thought of as aquarium pets in ...

A properly dressed male guppy, with its gaudy blue spots and brilliant splashes of orange, can't help but stand out. But for a fish that spends its life swimming among predators, it seems that good ...

From our perspective, guppies lead simple lives—eating, reproducing, and, after a couple of years, dying. Apply a little evolutionary pressure, though, and they can evolve larger brains that make them ...

Thanks to a unique combination of biology and ecology, the guppies have provided researchers with insights into evolution for decades. Evans and Fitzpatrick have pushed those insights a step further, ...
