Ticked Off

April 01, 2011 by Barry Breckling

Ticks can be trouble, yet you can’t help but admire their toughness as they cling to vegetation waiting for a meal to come within arm’s length. Fortunately for us, some of those meals come from western fence lizards, whose blood neutralizes the pathogen that causes Lyme disease. Now that’s a handy bit of natural selection!
