Lazarus taxa” is an appropriate name for species that seem to have been resurrected. However, the Lazarus whom Jesus raised from the dead was a householder who lived with his sisters, Mary and Martha, in Bethany (John 11). The beggar named Lazarus appeared in a parable that Jesus told to his followers (Luke 16).

Sid Perkins’ article on long-missing species validates a long-held principle of logic, namely, that one cannot prove a negative. It reminds me of an oft-cited legal warning: “Absence of proof does not constitute proof of absence.”
