synomorphy
A shared, derived character or trait that originated in the most recent common ancestor of a group of organisms and was inherited by all its descendants. Within the spaces of Main Street – the shops and civic buildings, the throughfare, the sidewalks – are embedded a wide array of behaviors that are “Main Street” in their character… A fully assembled Main Street, viewed in all the dimensions we have described, acts as a ganglion transmitting information in Many directions.
