The gut microbiota has undergone radical changes. Human gut anatomy are unaltered but the microbial ecosystems have degraded. Health may mirror these changes and how we acquire our microbiota including the ways we procure our food -- shifting at the neolithic from tedious hand foraging to village crops to (now) massive, post-industrial farming operations and livestock production. Our distance from the dirt is immeasurable. New technology allows characterization of the ancestral gut. Comparatively, species in ancestral and non-industrialized guts are robust in diversity and less fragile in balance. Ways to resolve this 'gut identity' crisis involve re-wilding and revisiting the ancestral, soil-connected gut.
