With the work Phylogenie der Schlitzschraube Edith Payer refers to the early days of natural history museums, whose exhibited collections where used to produce knowledge. In collaboration with biologist Stefanie Wong the artist created a taxonomy of screws, nails and other ironware. These objects were part of the inventory of the former Viennese hardware store Klimesch, which was purchased by the Volkskundemuseum Wien in 2013 to reflect on its own activities. 

By intensely exchanging on the formal characteristics of the metal parts, the artist and the biologist classified the ironware on the basis of hierarchically organized, scientific taxonomies in order to create a system of phyla, classes, orders or genera and subspecies. By a more detailed visual examination of the board the decisions and assertions become traceable – for example, which object was identified as the first of its kind serving as an "ancestor" of all the others, or which characteristics were assumed to determine the establishment of new genera. 

Fixed with construction adhesive, which was also available in Mr. Klimesch's hardware store and actually makes many of the taxonomized objects redundant, the hardware finally lost its intended use and finds its new purpose on the display. The connecting lines – drawn with a pencil – suggest that any classification system is bound to space and time and therefore relative.
