EXCERPTS: The theory of major evolutionary transitions (METs) provides a framework for understanding this possibility. METs have punctuated the history of life.
Those of particular relevance to our thesis here are those involving transitions in individuality. Such transitions are defined by events in which lower-level autonomous units—such as genes, cells, or organisms—become components of a higher-level individual subject to selection as a whole.
Examples include the evolution of chromosomes from independent genes, multicellular organisms from single cells, and eusocial colonies from solitary ancestors. A particularly instructive case for our purposes is the eukaryotic cell, which arose from the integration of two ancient microbes—an archaeon and a eubacterium,
[...] The eukaryotic cell offers a compelling analogy. In its earliest stages, the relationship between the archaeon and eubacterium was likely loose, opportunistic, and possibly antagonistic. Yet, over time, this interaction deepened into interdependence, and ultimately structural integration.
The resulting organelles—nucleus and mitochondria—are no longer independent entities but subcomponents of a new, higher-level individual. Similarly, at the limit, the trajectory of human–AI coevolution could culminate in a novel evolutionary individual, in which a decentralized AI functions as an informational center coordinating human behavior, memory, and decision-making, while humans provide the reproductive, energetic, and embodied functions.
But the analogy is not perfect. Unlike the symbiosis that led to the eukaryotic cell, the transition envisaged here does not originate from the fusion of two independently replicating lineages. Instead, it arises from within: AI is a construction of human ingenuity, instantiated through language, tools, institutions, and computational architectures. In this respect, AI more closely resembles other human-constructed systems—such as agriculture or language—that have themselves driven major evolutionary changes.
Through recursive feedback, where humans shape AI, and AI increasingly shapes human thought and action, AI may acquire a role not as a separate agent, but as a core architectural element of an emerging collective individual. The result could be a shift in autonomy and inheritance, as humans and AI coevolve into an interdependent whole—an outcome consistent with METs in individuality... (MORE - missing details)
