Lizards evolve in under 40 years

Amazing story this;

Italian wall lizards introduced to a tiny island off the coast of Croatia [in 1971] are evolving in ways that would normally take millions of years to play out, new research shows. In just a few decades the 5-inch-long (13-centimeter-long) lizards have developed a completely new gut structure, larger heads, and a harder bite, researchers say.
