Decomposition is a very complicated business, involving an interplay of
biological, chemical and physical factors. Minor changes in the chemistry
of an environment can have profound effects on the microbial populations
lurking inside. Sometimes the inside of the body decays faster than the
outside, other times the opposite is true; and when the outside of the body
survives long enough to be preserved, different types of integument show
... and here he hits the nail squarely on the head. If a full and proper
cladistic analysis is appropriate for this publication, then surely a full and
proper taphonomic analysis is required too. Absence of evidence is not evidence
of absence. Again.
