Tom Wessels is a terrestrial ecologist and Antioch University New England professor emeritus. He has authored five books.

In this film, Tom shows us examples of animal and plant species that have evolved together and thus shaped each other's ecological roles. Organisms become more and more complex through evolutionary time, and Tom takes us into the forest to explain the ecological principles at work here, with examples of plants, birds, lichens, and insects. A fascinating field trip!
