The killer rat-kangaroo's tooth

Article Abstract:

The molars of the Ekaltadeta ima, an extinct marsupial species known as the powerful-toothed giant rat-kangaroo, is examined as evidence of imperfect design in evolution's natural selection process. While other marsupials discard the second premolar (P2) when the third premolar (P3) erupts, P2 is retained in this species to buttress the massive P3, even though bone would be a more effective and efficient buttress.
