Martin Cadra has a wonderful blog focusing on non-Darwinian views on evolution. He recently highlighted some rare publications by field biologists who provide empirical evidence that challenges the idea that Darwinian evolution is the source of butterfly mimicry. Here is an excerpt:
Since Darwin’s time mimicry is presented as one of the best example of the efficiency of natural selection. Several species should have been shaped by natural selection to resemble or mimic dangerous or poisonous species. It is supposed that protected by their shape and coloration they deceive their predators. Thus mimicry confers them a survival advantage. In many cases mimicry is believed to be found among butterflies where palatable species mimic unpalatable ones (so called Batesian mimicry). In some cases two or more unpalatable species look alike. In this case they should be protected more effectively because their predators learn to avoid them only once. This is called Müllerian mimicry. And in some cases there is a whole bunch of Batesian and Müllerian mimics that look alike. This is called the mimicry ring.
