Biological genotypes do not code directly for phenotypes; developmental physiology is the control layer that separates genomes from capacities ascertained by selection. A key aspect cellular competency, since cells are passive materials but descendants of unicellular organisms with complex context-sensitive behavioral capabilities. To probe effects different degrees competency on evolutionary dynamics, we used an simulation in context minimal artificial embryogeny. Virtual embryos consisted a single axis positional information values provided cells’ ‘structural genes’, operated upon cycle which embryos’ fitness was proportional to monotonicity axial gradient. Evolutionary dynamics were evaluated two modes: hardwired development (genotype encodes phenotype), and more realistic mode interact prior evaluation function (“regulative” development). We find even ability improve their position embryo results better performance search. Crucially, observed increasing masks raw encoded structural genes, selection favoring improvements its problem-solving over genome. This suggests existence powerful ratchet mechanism: evolution progressively becomes locked intelligence agential substrate, reduced pressure kind feedback loop increasingly puts effort into software than perfecting hardware explains very puzzling divergence genome anatomy species like planaria.

The applicability of computational models to the biological world is an active topic debate. We argue that a useful path forward results from abandoning hard boundaries between categories and adopting observer-dependent, pragmatic view. Such view dissolves contingent dichotomies driven by human cognitive biases (e.g., tendency oversimplify) prior technological limitations in favor more continuous view, necessitated study evolution, developmental biology, intelligent machines. Form function are tightly entwined nature, some cases, robotics as well. Thus, efforts re-shape living systems for biomedical or bioengineering purposes require prediction control their at multiple scales.

Collective intelligence and individual are usually considered to be fundamentally different. Individual is uncontroversial. It occurs in organisms with special neural machinery, evolved by natural selection enable cognitive learning functions that serve the fitness benefit of organism, then trained through lifetime experience maximise rewards. Whilst mechanisms not fully understood, good models exist for many aspects cognition learning. intelligence, contrast, a much more ambiguous idea. What exactly constitutes collective often vague, might it frequently domain-specific. These cannot selected specifically purpose because collectives (except circumstances) evolutionary units, clear can learn way intelligences do since they singular locus rewards benefits. Here, we use examples from evolution developmental morphogenesis argue these apparent distinctions as categorical appear. Breaking down such enables us borrow expand existing framework particular connectionist familiar context networks.

This metaphor is paradigmatic case deterministic, mechanistic framework that focuses biomedical intervention strategies on altering members this network up-/down-regulation links them—rewiring molecular hardware.

Advances in science and engineering often reveal the limitations of classical approaches initially used to understand, predict, control phenomena.

The ideas of self-observation and self-representation, the concomitant idea self-control, pervade both cognitive life sciences, arising in domains as diverse immunology robotics. Here, we ask a very general way whether, to what extent, these make sense. Using generic model physical interactions, prove theorem several corollaries that severely restrict applicable notions self-observation, self-control. We show, particular, adding observational, representational, or control capabilities meta-level component system cannot, even principle, lead complete representation whole. conclude self-representation can at best be heuristic, self models general, empirically tested by systems implement them.
