Summary
This study distinguishes law-based and evolutionary sciences by epistemic regimes, not subject matter. It introduces Stability-Driven Assembly (SDA) to model evolutionary dynamics, highlighting population memory as key to open-ended processes.
Area of Science:
- Theoretical Biology
- Philosophy of Science
- Complex Systems
Background:
- Scientific disciplines are broadly categorized into law-based sciences and historical sciences.
- This division is often attributed to differences in subject matter, but this work posits it stems from distinct epistemic regimes.
- Law-based sciences utilize episodic closure, idealizing systems to maintain consistent rules, which aids prediction but obscures evolutionary dynamics.
Purpose of the Study:
- To formally distinguish between law-based and evolutionary scientific approaches.
- To introduce a novel framework, Stability-Driven Assembly (SDA), for modeling evolutionary dynamics.
- To develop a unified taxonomy of scientific inquiry, including formal possibility and constructive potential.
Main Methods:
- Formalization of scientific regimes using λ-calculus to represent compositional objects.
- Development of the Stability-Driven Assembly (SDA) framework, a minimal non-equilibrium model.
- Analysis of differential persistence and population-level dynamics in the absence of genes or replication.
Main Results:
- Episodic science involves isolated λ-reductions, while evolutionary science studies populations of λ-instantiations with self-modifying dynamics.
- The SDA framework demonstrates how population feedback reshapes dynamics, leading to irreducibly sequential and self-modifying processes.
- A four-quadrant taxonomy is proposed, locating episodic science, evolutionary science, formal possibility, and constructive potential.
Conclusions:
- Population-level memory is identified as the structural element transforming law-governed episodes into open-ended evolutionary processes.
- The "No Free Telos" constraint is derived, stating prediction costs in constructive systems cannot be reduced below simulation costs.
- This framework bridges episodic and historical sciences by focusing on the emergent properties of evolving systems.

Evolutionary Psychology
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...
The Evidence for Evolution
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.The collection of fossils within sedimentary rocks give a record of common ancestry and often depicts the history of evolution.
Criticisms of the Evolutionary Perspective
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.

What is Evolutionary History?
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.Phylogenetic trees illustrate the evolutionary relationships among these organisms. Scientists infer organisms’ common ancestry by evaluating shared morphological and genetic characteristics. Together, the fossil...
Hardy-Weinberg Principle
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.In the early 20th century,...
Genetic Drift
Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.Life is not fair. A deer grazing contentedly in a field can have her meal cut tragically short by a bolt of lightning. If the doomed doe is one of only three in the population, 1/3 of the population’s gene pool is lost. Random events like this can...
