Survival of the fittest may be the law in evolution, but sometimes survival of the sneakiest is the law of the jungle. All through the animal kingdom, there are examples of sneaky mimics. From the butterfly that looks like a leaf cutter ant, to a lizard that resembles an acid-spraying beetle, there are thousands of species that hide from predators by looking like another animal. But how does this develop in the first place? And if it's such a good way of avoiding being eaten, then why doesn't everything out there look exactly the same? We'll talk to a Canadian scientist who's made a career of trying to answer these questions.
Plus - a shrinking brain from chronic pain.
All this and more on Quirks & Quarks, Saturday right after the noon news on Radio One.

>From human evolution, to the history of a tree, to the stories behind our dreams, we look at some of this season's most intriguing science books. First, renowned evolutionary biologist Richard Dawkins has rewritten the story of our evolution with a new twist in The Ancestor's Tale. He tells the story in reverse, climbing down the tree of life from the present to meet the creatures we used to be. It's a long, strange trip, with some fascinating new insights into life on our planet, and what makes us what we are. Next, Wayne Grady and David Suzuki bring us the life story of one magnificent and extraordinary Douglas fir; and then Alan Hobson takes us inside our subconscious and explains the 13 Dreams Freud Never Had.
That's all on Quirks & Quarks, Saturday right after the noon news on Radio One.
