Astrobiology, 2002•liebertpub.comThis paper deals with the difficulty of decoding the origins of natural structures through the
study of their morphological features. We focus on the case of primitive life detection, where
it is clear that the principles of comparative anatomy cannot be applied. A range of inorganic
processes are described that result in morphologies emulating biological shapes, with
particular emphasis on geochemically plausible processes. In particular, the formation of
inorganic biomorphs in alkaline silica-rich environments are described in detail.
