Native Lizards Evolve to Escape Attacks by Fire Ants
Found on PhysOrg on Monday, 19 January 2009
Penn State Assistant Professor of Biology Tracy Langkilde has shown that native fence lizards in the southeastern United States are adapting to potentially fatal invasive fire-ant attacks by developing behaviors that enable them to escape from the ants, as well as by developing longer hind legs, which can increase the effectiveness of this behavior.
In the future, Langkilde plans to study the mechanism behind the behavioral changes following invasion. Non-responsive lizards tend to be killed and removed from the gene pool.
Darwinism in action. Take that, creationists.
