There's a new article by our Earthsave Canada president out there that you might enjoy. It's at http://www.aquarianonline.com/mystery-unites-us/
As Dave says, "Dogs and cats, cows and pigs, chickens and crows all clearly share the basic experience of life that we do. Fish, too, show clear signs of conscious awareness. Charles Darwin saw it even in the lowly earthworm. I’m not so sure that he was right about that, but I do know that they can be trained to solve very simple mazes. Fruit flies are much better at solving mazes, though; and they can even learn from each other."
