One-third of "extinct" mammals are rediscovered

A bit of positive news - conservationists can sometimes be wrong when declaring an animimal missing or extinct. According to Dr Diana Fisher of the University of Queensland, Australia, of 187 mammals which have been thought missing since 1500, 67 have turned up. Scientists in the 20th century have been wrong more often than their earlier counterparts - although, in this case, being wrong is a good thing.
