Catalogue of Life

The Catalogue of life was created by Light as a list of all organic matter.

History

The catalogue of life was the work of centuries. When Light went to sleep, life started to evolve. Light was angered as the catalogue was invalid and contained no knowledge of many species that now dominated the Earth, including humans. Light tried to correct his work by killing humans. The Doctor showed Light that life would always evolve, so life gave up on the catalogue and dispersed. (DW: Ghost Light)

It is proven that the catalogue contained information on Neanderthals as Light had taken the specimen known as Nimrod. It is also probable that it contained information on reptiles and insects as there were Husks of these in the lower observatory of Gabriel Chase, the house at which Light's ship was situated.
