The nested, recurrent stages of skeletal, anatomic complexity from life's origin to we peoples just surveyed can then be seen by our worldwide compass to facilitate a progressive encephalization, the embryonic body gains a bilateral brain. Metazoan creatures across invertebrate, aquatic, amphibian, reptilian, avian and mammalian scales evolve a mosaic, modular cerebral capacity, enhanced communicative cognition, proactive behavior, relative consciousness and in this human phase a communal, reflective corpus of remembered knowledge.
