Concerning evolution, how does it explain the bug that changes itself to look like a leaf? Does it explain it the same way as other forms of life? I've heard tell of a butterfly or more probably a moth, I can't quite remember now, but it evolved into two different types. One type, because it spends its time mostly in rural areas, is white in colour, but the other type, because it spends most of its time in and around a dirty industrialised area, is more grey in its colouring.

But the bug resembling a leaf seems a bit of a stretch.
