title: Conservation: losing biodiversity by reverse speciation.
abstract: A large fraction of the world's species diversity is of recent evolutionary origin, and has evolved as a by-product of divergent adaptation in heterogeneous environments. Recent research provides a dire warning that homogenizing environments may cause the rapid loss of such species through a reversal of the speciation process.
