Good Enough

Spare a thought for the poor guppy fish, who lives a miserable existence but teaches us something important about forecasting.

Small, brightly colored, and terrible at defense, the guppy faces an unusually high rate of predator attacks. Birds eat guppies. Small fish eat guppies. Big fish eat guppies. Crabs eat guppies. It’s everyone’s favorite lunch.

How does a species under so much threat avoid extinction?

In short, guppies get busy as soon as they’re born. They can reproduce at seven weeks old, and deliver new offspring every 30 days. By the time a six-month-old guppy is eaten by a bird it might be a great-great-grandmother. The family lives on.

But this evolutionary trick has a nasty flip side.
