The Survival Code: An Evolutionary Framework for Biological General Intelligence

Abstract Human intelligence and consciousness represent the culmination of billions of years of evolutionary processes, yet their foundations remain rooted in a simple, ancient imperative: survival. This paper proposes a conceptual framework viewing DNA as an interdependent "survival code"—a deterministic set of molecular instructions that, when executed in compatible biological and environmental "runtime" environments, drives replication, adaptation, and persistence. Drawing from abiogenesis hypotheses, evolutionary biology, and systems theory, we trace the code's progression from primitive replicators to multicellular complexity, emphasizing the environment's role as primary sculptor through selection, phenotypic plasticity, and niche construction. The brain emerges as navigational hardware for predictive integration, enabling general-purpose intelligence in humans via neural scale and cultural amplification. This "biological AGI" paradigm unifies gene-centered evolution with computing analogies, avoiding teleology by framing outcomes as statistical differentials under constraint. Implications extend to bio-inspired artificial general intelligence (AGI), suggesting that true agency and adaptability require embodied stakes and selective pressures. This model offers a non-reductive lens for understanding life's informational trajectory and its relevance to engineered systems.
