Humans are defined by their cognitive abilities, large cerebral cortex, and capacity for deductive and inductive reasoning. Personality is influenced by traits like stability and extroversion/introversion, while gender refers to masculine and feminine traits rather than biological sex. Anthropological evidence indicates humans evolved in Africa and are classified as primates in the family Hominidae. Culture is defined by shared values, norms, and symbols within a society and influences human behavior and social dynamics.
