For the next thirty seconds you will be reading a cop-out. Because I am living in a flu-fog this week and can't even read an email and get it to make sense, I'm going to just share a really, really cool fact I ran across last week about one of my favorite subjects--butterflies.
It is simply this: memory survives metamorphosis.
Apparently when the caterpillar turns into bug soup within the chrysalis--with the help of eroding digestive juices (yummy)--the components of the brain that retain memory remain intact.
They apparently learned this by exposing caterpillars to the smell of nail polish remover and at the same time giving them a mild electric shock. The older the caterpillar was when exposed to this combination, the greater his chance of remembering to avoid the smell of nail polish after the metamorphosis.
