Human evolution has reached a critical inflection point. Biological evolution culminated in Homo sapiens with advanced cognitive capacity, but ethical evolution (using the cognitive advantage for behavioral restraint) has not kept pace with humanity’s expanding technological and institutional power. This imbalance now represents the primary existential threat to the species. This work argues that inequality in access to basic human survival needs—food, water, healthcare, and education—is the ultimate driver of intraspecies human conflict, manifesting through malignant forms of tribalism: ethnic, racial, religious, ideological, socio-economic, and geographic. The survival of the species now depends on a conscious transition from struggle for survival to struggle for coexistence.
