The fossil evidence shows that the Sardinian pika first got to the islands of Corsica and Sardinia during the last Ice Age when sea level was lower, connecting the islands to the mainland. Over time the Sardinian pikas developed higher set teeth and bulkier bodies. There were several species of natural predators on the islands including the Sardinian dhole and birds of prey. People arrived in Corsica-Sardinia around 8,000 BC and there is bone evidence that they were on the diet of people. The population most likely began to decrease with the arrival of invasive species brought by people such as cats, dogs, rats, and weasels. With the arrival of hares and rabbits, came transmissible diseases that also seemed to have taken a toll on the Sardinian pika population. There is conflicting information as to the extinction date of the Sardinian pika. Some resources seem to indicate that the Sardinian pikas died out in 289 during Roman expansion. There were some indications that these pikas may have existed up into the early 1700's. Either way the Sardinian pika is now extinct. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The Sardinian pikas might be a candidate for de-extinction. Scientists would potentially use DNA from the bones that have been obtained from caves in Sardinia. If the Sardinian pikas did return to the islands of the Mediterranean, would it be able to survive there now? We may never know.
