On Fishing Evolution

Speaking of worms and historical first times, imagine the first time someone used a worm to catch a fish.

Fish live in the water.  Worms don't.  Sure, a few worms fall off banks or roll into ponds and rivers in rotten logs or flow with topsoil in floods, but I'm going to go ahead and challenge science to show me a fish that depends on worms as a food source.  Seems evolutionarily impossible to me.

But, as many of us learned when we were little, fish go crazy over worms.  Worms are to fish what ice cream sandwiches are to humans.

And, somehow, someone discovered that.  Discovered the worms part, I mean.  Though someone did also discover the ice cream sandwich.  To that person, I offer thanks and congratulations.

But back to the wormbait innovator...

Maybe he dropped a worm into a stream and saw a fish eat it.  And, maybe, because he'd seen fish eat lots of other things before, he was impressed with the level of satisfaction he could sense in the swish of its tail.  So maybe he dropped another worm, and maybe the fish smiled, winked, and ate that too, or maybe another fish swooped in and jumped for joy.

But then why did the dude have worms?  I mean it's pretty rare for a person to be carrying a worm.  Was he a worm-eater too?  Or was he carrying them back to his garden?  Showing his kids how weird they are?  Discovering for himself how weird they are?

I feel like there might be an obvious answer to all this, but my imagination doesn't seem to want to let me find it.

Oh well.  Kinda fun this way.
