This article seems to confuse 'selection' for 'evolution'. These lizards haven't evolved - their genes are unchanged. It is their population that has been selected against for new pressures. This will potentially drive evolution genetically, however on such a short time scale there has been no evolution yet. I guess you could argue that evolution describes the state of the current gene pool, however I'm not sure that is a particularly common measure.
