Lizards on islands

At www.physorg.com/print191781096.html April 29th … a genetic study of lizards isolated geographically on islands, sometimes for thousands of years, possibly even millions of years, do not appear to have evolved into separate species as demanded by conventional evolutional theory. They remained stubbornly like their predecessors. They were also capable of reproducing with similar species from elsewhere. However, the PLoS Genetics paper says that research was ongoing.
