This paper will present evidence to support ontogenetic and phylogenetic parallels and draw from these comparisons to further illuminate our understanding of micro and macro human development. Individual and collective stages of physical, psychological and spiritual development will be compared and their homologous structures examined. Developmental stage theories for the following areas will be briefly presented and their descriptions of the ontogenetic and phylogenetic stages of infancy, childhood, adolescence and adulthood generalized and compared for commonalities: cognitive (Piaget), moral (Kohlberg, Gilligan), ego (Loevinger), needs (Maslow), socio-emotional (Erikson), self sense (Cook-Greuter), faith (Fowler), cultural (Beck & Cowan), social/cultural/economic worldviews (Wilber) techno-economic (Lenski), sociocultural (Gebser), religious systems (Bellah), epochs (Habermas) and others. Implications of this research on how we might help facilitate human development individually and collectively will be presented. (Contains 2 tables.)
