I've never been able to see where or why anyone sees mimicry as some unusual problem for classic evolution. What we see as mimicry is just a history, a snapshot taken at one point in the trip.
One of my favorite examples is a recent study on mimicry among poison dart frogs in areas where more than one species of poison dart frog exists. What I enjoyed most about the study is that it seems the most successful mimics are those that mimic the less poisonous variety.
When I first heard that I was surprised. Why wouldn't the ones that looked like the most poisonous species be more successful?
Then I stopped to think about it.
Predators that try to eat the most poisonous species likely die while learning. Those that try to eat the less poisonous species might survive, but remember the experience.
The former learn their lesson, but the don't retain it. They dead. The later learn their lesson and in the future avoid anything that looks like what made them sick.
The result is that the frogs that look like the less poisonous species have an advantage over those that look like the more poisonous ones.
Pretty neat. Simple, elegant and absolutely no need for any intervention.
