Scientists working along the equatorial coasts of the Sargasso Sea have discovered fossils of Vacanti mice that are indistinguishable from modern specimens in Massachusetts. The fossil mice are found in strata from the Nevocene era, laid down between 55 and 50 million years ago. Dr David Dents of the Ivanhoe Foundation thinks these mice remained morphologically unchanged for so long because their environment was sterile and lacked large predators, and because their breeding was restricted due to their lifestyle involving the isolation of individual animals.
