Abstract

The search for extraterrestrial life centres on the search for ‘biosignatures’. Yet there is little agreement within the scientific community with respect to what exactly it is for something to be a biosignature. Existing accounts are presented and criticised. An alternative is provided that resolves problems with existing accounts by distinguishing clearly between types and tokens.
