What is coevolution and how does it relate to evolution?
Coevolution is a type of evolution that occurs when members of two different species interact extremely closely with one another. The result of this close interaction is that they develop adaptations that are customized to thier relationship with each other: thus each species acts as a force of natural selection on the other species. Example: the Orchid and the Orchid Mantis that you saw in the film. The insect evolved in such a way that its body shape and color match the flower on which it lives.
