  The standing crop of correlations in metazoan communities may be assessed by
an inventory of niche structures focused inward and outward from the physical
boundaries of skin (self), gene-pool (family), and meme-pool (culture). We
consider tracking the progression from three and four correlation layers in
many animal communities, to five of six layers for the shared adaptation of
most humans, with an attention-slice model that maps the niche-layer focus of
individuals onto the 6-variable space of a 5-simplex. The measure puts
questions about the effect, on culture and species, of policy and natural
events into a common context, and may help explore the impact of
electronically-mediated codes on community health.
