Lizard Wizard Johnathan B. Losos, lately of Harvard University, has released results of a very interesting experiment on lizards inhabiting small cays in the Bahamas showing surprisingly rapid evolution - like, within a single generation - via the introduction of a new predator.

In order to appreciate the details, a little background on previous findings is warranted. Losos revealed in 1998 that Caribbean Lizards Evolve Independently on separate islands, despite an end result that shows very similar morphology and behavior. In evolutionary terms, this is known as "convergence."
