Description of Decision Rules for Rejecting Abiotic Hypotheses (Criterion #8)

Rule	Description
A	Evidence for Darwinian evolution precludes an abiotic origin even in the absence of any other feature.
B	Evidence for a spectral signature of pigments precludes an abiotic origin even in the absence of any other feature.
C	Evidence for DNA or RNA precludes an abiotic origin even in the absence of any other feature.
D	Evidence for both cell-like features and structural preferences in organics (nonrandom and enhancing function, such as a repeating charge or chirality) precludes an abiotic origin.
E	Evidence for both cell-like features and patterns of complexity in organics precludes an abiotic origin.
F	Evidence for both a response to stimulation and structural preferences in organics precludes an abiotic origin.
G	Evidence for both a response to stimulation and patterns of complexity in organics precludes an abiotic origin.
H	Evidence for both structural preferences and patterns of complexity in organics precludes an abiotic origin.
I	Without evidence for structural preferences in organics, and unless one of the above rules applies, an abiotic origin cannot be precluded.
J	Without evidence for patterns of complexity in organics, and unless one of the above rules applies, an abiotic origin cannot be precluded.
K	Without evidence for either structural preferences or patterns of complexity in organics, an abiotic origin cannot be precluded, regardless of whether there is evidence for cell-like morphologies or a response to stimulation.
