Supplementary Information

The first three sections below provide some background information on Avida and the logic functions that digital organisms perform. The fourth section provides some additional data on phenotypic and genomic evolution along the line of descent in the case-study population, up to the time of origin of the EQU function.

I. Avida instruction set: [PDF] [HTML]
II. One- and two-input logic operations: [PDF] [HTML]
III. Shortest hand-written EQU program: [PDF] [HTML]
IV. Phenotypic and genomic evolution along the line of descent in the case-study population through the origin of the EQU function at step 111 [PDF]
