A sound knowledge of the number of species on earth is vital for predicting extinction rates and subsequently for our understanding of conservation and biodiversity. To date, estimates of these parameters remain wildly inconsistent. Predictions for the number of living species can vary by a factor of 100 and extinction rates by even greater amounts. [...]
