• Answer:

  Here's a start: 1. Since you're dealing with plants, orchids are a good example of co-evolution. The intricacy of the flower is the result of its evolving to look like the insect that pollinates it. That is, as the insect's morphology evolved, so did the flower's. Evidence would have to involve fossilized ancestors of both.
