Gene-Centric Biology and APS — Why Genes Are Not “In Charge”

Abstract

Gene-centric biology has been one of the most influential frameworks in modern evolutionary theory, but it is often misinterpreted as an account of what drives life itself. This article clarifies the role of genes within the APS framework, showing that genes are indispensable mechanisms of inheritance operating within viability-oriented organisation, not the origin of biological agency or the ultimate basis of evolutionary explanation.

The Gene-Centric Question

Are genes “in charge” of life?

This question has shaped modern evolutionary debate, most visibly in the contrast between gene-centric accounts and organism- or system-oriented perspectives. In gene-centric formulations, evolution is described as change in gene frequency over time, and organisms are often treated as vehicles through which genes persist. In response, systems-oriented approaches emphasise regulation, physiology, and environmental interaction, arguing that genes do not determine biological outcomes in isolation.

APS approaches this debate differently. It does not ask which component is primary. It asks a prior question:

What organisational condition must exist for evolution to occur at all?

This shift reframes the entire discussion.

Why the Debate Persists

The persistence of the gene–organism debate reflects a deeper issue in biological explanation. Many frameworks assume that explanation must ultimately identify a privileged component—a driver located at a particular “level” of organisation.

This assumption encourages a hierarchical view:

genes, cells, tissues, organisms
with causation imagined as flowing upward or downward

Such representations resemble engineered systems, where control is located in identifiable components. But living systems do not operate through chains of command.

In biological systems, causation is distributed and reciprocal:

molecular processes influence cellular organisation
cellular activity reshapes molecular dynamics
physiological regulation modulates gene expression
organismal activity alters environmental conditions

Causation propagates across scale rather than originating from a single source.

APS therefore replaces hierarchical explanation with an explanatory grammar of agency, process, and scale, in which biological organisation is understood as multiscale, constraint-closed, and dynamically sustained.

What Gene-Centric Biology Gets Right

Gene-centric models have extraordinary explanatory power.

They:

track heritable variation across generations
enable population-genetic modelling
support molecular and comparative biology

APS does not reject this framework.

Genes are indispensable to biological systems. They:

stabilise patterns of organisation
enable reliable inheritance
provide mechanisms for variation

Without genetic systems, the continuity of life across generations would not be possible in its current form.

The issue is not whether genes matter.

The issue is whether genes explain life itself.

The Conceptual Shift

Gene-centric accounts often move from a methodological claim to an ontological one:

from “genes are useful explanatory units”
to “genes are the drivers of life”

APS resists this move.

Genes explain how patterns are transmitted. They do not explain why transmission is biologically meaningful.

That meaning arises only within systems that:

maintain themselves
regulate their own conditions of existence
distinguish between viable and non-viable states

In APS terms, these are viability-oriented, constraint-closed organisations.

Evolutionary processes—inheritance, variation, selection—operate only within such systems.

The APS Starting Point

APS begins from a constitutive claim:

Life is the organisation of biological agency—viability-oriented, self-regulating activity.

Living systems do not merely persist. They actively sustain the conditions required for their continued existence. This activity establishes an intrinsic asymmetry between conditions that support persistence and those that undermine it. This asymmetry is biological normativity.

Within this framework:

inheritance is the stabilisation of organisation across generations
variation is the modification of that organisation
selection is the differential persistence of viable organisation

Evolution is therefore:

the historical transformation of viability-oriented organisation across scale

Genes participate in this process, but they do not ground it.

APS Box — Gene-Centric vs APS Explanatory Grammar

Gene-centric biology and APS do not simply disagree about which biological component matters most. They represent different explanatory grammars—different ways of organising what counts as a cause, a unit, and an explanation in biology.

The contrast is not between “genes” and “organisms,” but between component-centred explanation and organisation-centred explanation.

Gene-centric grammar

Evolution = change in gene frequency

Genes are units of selection

Organisms are vehicles for replicators

Information flows from genes outward

Causation is located at a privileged component

Genes explain biological order

APS grammar

Evolution = transformation of viability-oriented organisation

Viability-oriented organisation is what selection operates on

Organisms enact constraint-closed agency

Organisation constrains and integrates genetic processes

Agency, process, and scale are co-constitutive

Organisation makes genetic processes biologically meaningful

Gene-centric models successfully describe patterns of inheritance and evolutionary change. APS does not reject these models. It clarifies their domain of validity.

Gene-centric explanations operate within systems that already:

maintain themselves

regulate their own conditions of existence

sustain viability across time

APS begins at this prior condition.

Within viability-oriented, constraint-closed organisation:

genes stabilise and transmit structure

genetic variation contributes to transformation

selection reflects differential persistence of viable organisation

Key Point. Gene-centric biology explains how inheritance operates, but APS explains the organisational condition that makes inheritance, variation, and selection biologically meaningful.

Genes Within Biological Organisation

Genes matter profoundly in APS.

They:

encode and stabilise constraint organisation
enable transmission of viability-relevant structure
support generational continuity and variation

But they operate within systems whose organisation:

constrains gene expression
regulates replication
maintains the conditions under which genetic processes occur

DNA does not replicate itself. Replication requires:

metabolic activity
cellular machinery
regulatory coordination
environmental coupling

All of this is organised by the living system.

Genes are therefore neither sovereign drivers nor passive components. They are mechanisms within ongoing biological organisation.

Key Point
Genes are indispensable mechanisms of inheritance, but agency—viability-oriented organisation—is the condition that makes heredity and selection biologically meaningful.

Why Genes Are Not “In Charge”

To ask whether genes are “in charge” is to mislocate causation.

It assumes that biological explanation must identify a controlling component. But in living systems:

causation is multiscale
organisation is distributed
activity is reciprocally sustained

No single component—genetic, cellular, or organismal—holds explanatory primacy.

APS therefore rejects both:

gene-centrism (genes as drivers)
organism-centrism (organisms as controllers)

Instead, it understands biological systems as constraint-closed organisations in which agency, process, and scale are co-constitutive.

Genes participate in this organisation. They do not govern it.

Evolution Without Genetic Reductionism

APS does not deny evolution. It clarifies its conditions.

Evolution is not genes competing for replication in isolation. It is the long-term transformation of viability-oriented organisation across generations.

From this perspective:

selection operates on organised systems
genetic change is one pathway of transformation
persistence of organisation remains primary

Genes are inherited because living systems persist.

Life does not persist because genes “seek” to be inherited.

A Clarifying Analogy

Genes are often described as the “instructions of life.” This analogy can be misleading.

Architectural blueprints are essential for constructing and reproducing a building. But the stability of a building depends on the organised relations among its components—foundations, materials, and structural integration.

Similarly:

genes contribute to biological organisation
but persistence depends on the coordinated activity of the system as a whole

Genes transmit and stabilise organisation. They do not constitute the organisational condition that makes life possible.

Conclusion

Gene-centric biology remains one of the most powerful tools in modern science. Its success in explaining inheritance and evolutionary change is not in question.

But it does not define life.

Living systems are not organised for genes. They are viability-oriented, constraint-closed organisations that sustain themselves in the present and sometimes reproduce across generations.

Genes matter because they participate in this organisation.

They are not “in charge” of it.

Key Point
Genes are mechanisms within life, not the basis of life itself; biological agency—viability-oriented organisation—is the condition that makes genetic inheritance and evolution possible.
