It took only a few hundred years for humans to wipe out 50 million years of evolution on New Zealand
In their recent study, Dr Valente and his collaborators wanted to answer two basic questions: “how far have humans perturbed this unique and isolated biological assembly from its natural state?” and “how deep will the evolutionary impact be if currently threatened species go extinct?”
The data revealed it would take approximately 50 million years to recover the number of species lost. Further, the data showed that, if all species that are currently under threat are allowed to go extinct, it would require an additional 10 million years of evolutionary time to return to the species numbers of today.
New Zealand, whose government consists of responsible, thinking adults, is taking this threat to their endemic avifauna seriously.
