A non-existent endangered species

A DNA test allegedly proves that a protected "species," the Preble's meadow jumping mouse, is not a separate species at all. The research "suggests the Preble's mouse in fact never existed. It instead seems to be genetically identical to one of its cousins, the Bear Lodge meadow jumping mouse, which is considered common enough not to need protection."

One wonders how many more similar endangered non-species will be found to have deprived people of their property rights over the years. Junk science or political science?
