I don't know why but your comment made me remember a novel[1] I read thirty-some years ago about a temple found deep in the sand of the Sahara desert. Sometime later, an archeologist gave himself permission to defecate in a corner of the temple, only for his wastes to be absorbed by the temple in a few hours, which told him the temple was actually a living biological structure.

As one who has had occasion to tidy up after wasps who were little accustomed, though palpably interested, quite so closely to share human habitation, you make me wish I read French. Do you happen by chance to know if the work has had a worthy English translation?
In alchemy and western esoterica, excrement is associated with the tenth sephirah, the 10s of the Tarot minor arcana, and symbolizes the end result of a process and any remaining waste byproducts, for obvious reasons. In The Holy Mountain's (1973) depiction of the alchemical magnum opus, The Fool's excrement is transmuted into gold, symbolizing the awakening of unconscious, reactive matter into fully enlightened and integrated, free willed, egoic man.

Edit: This also seems like a decent opportunity to bring up the scatological Luther.

In fact, by pretty much any measure, most life does not defecate (because they have no digestive tract).
