For thousands of years, humans have used a simple trick to catch fish, finding a new source of nutrition and expanding their diet past land animals.

Over the millennia, trillions of fish had been caught using this method. Millions of species of fish were caught using this simple trick.

However, fish continue to be caught using this very obvious method. Why is that? Why haven't fish evolved to NOT fall for something as simple as this?

You can even test it on fish you've caught yourself. Throw a fish into an aquarium and use the hook & bait method. The fish will continue falling for it.
