Lizards Undergo Rapid Evolution After Introduction To A New Home
In 1971, biologists moved five adult pairs of Italian wall lizards from their home island of Pod Kopiste, in the South Adriatic Sea, to the neighboring island of Pod Mrcaru. Now, an international team of researchers has shown that introducing these small, green-backed lizards, Podarcis sicula, to a new environment caused them to undergo rapid and large-scale evolutionary changes. "Striking differences in head size and shape, increased bite strength and the development of new structures in the lizard's digestive tracts were noted after only 36 years, which is an extremely short time scale," says Duncan Irschick, a professor of biology at the University of Massachusetts Amherst. "These physical changes have occurred side-by-side with dramatic changes in population density and social structure."

what if they evolve too much and start trying to kill us all?

Technically, there is no such thing as deevolution - it is just evolution (shift in the frequency of genes in a population over time). Also, that process is not evolution, since it happens on the level of individuals. It is another biological process.
