This paper explores the idea that information is an essential and distinctive feature of living systems. Unlike non-living systems, living systems actively acquire, process, and use information about their environments […]
![Semantic thresholds. Semantic Information identifies “semantic thresholds” where only specific mutual information between an agent and its environment impacts viability. (a) The foundational study [14] introduced this concept through counterfactual simulations assessing viability as information is scrambled. (b) Forager models [40] demonstrated such thresholds by adding noise to food detection sensors, revealing a peak in viability per bit of information at the threshold. (c) Similar thresholds appear in biosphere models like Daisy-World, responding to stellar forcing [41]. -- cond-mat.soft](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/01/The-Physics-of-Life-Exploring.png?resize=1200%2C720&ssl=1)
