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

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 explanatory frameworks assume that understanding a system ultimately requires identifying a privileged causal component. Within evolutionary biology this assumption has often encouraged the search for a primary driver of biological organisation, whether genes, organisms, developmental systems, or ecological processes.

Gene-centric interpretations gained influence partly because genes provide a powerful and tractable way of explaining inheritance and evolutionary change. Once genes are treated as the primary carriers of continuity across generations, however, it becomes tempting to regard them as the source of biological organisation itself. Organisms then appear as vehicles through which genetic information is transmitted, while developmental, physiological, and ecological processes are interpreted largely in terms of their contribution to genetic success.

APS argues that this way of framing the problem is misleading because it presupposes a hierarchical model of causation. Biological systems do not operate through chains of command in which one component directs all others. Molecular processes influence cellular organisation, cellular activity reshapes molecular dynamics, physiological regulation modulates gene expression, and organismal activity alters environmental conditions. Causation therefore propagates across interacting scales rather than originating from a single privileged source.

The question is consequently not whether genes or organisms are ultimately in control. The more fundamental issue is how continuity-producing organisation is sustained across multiple interacting processes and scales. APS replaces hierarchical explanation with an explanatory grammar centred on agency, process, and scale, within which biological organisation is understood as multiscale, constraint-closed, and dynamically maintained through time.

What Gene-Centric Biology Gets Right

APS does not reject gene-centric biology. On the contrary, many of the most successful achievements of modern biology have depended upon gene-centred methods and explanations. Population genetics provides powerful tools for modelling evolutionary change, molecular biology has revealed the mechanisms underlying inheritance, and comparative genetics has transformed our understanding of evolutionary relationships across the living world.

These successes arise because genes play a genuinely indispensable role within biological organisation. Genetic systems contribute to the reliable transmission of continuity across generations, provide important sources of variation, and help stabilise organisational patterns that persist through evolutionary time. Without genetic mechanisms, the continuity of lineages of organised persistence would not be possible in their present form.

The APS critique of gene-centrism therefore does not concern the importance of genes. It concerns the explanatory conclusions sometimes drawn from their importance. Demonstrating that genes are necessary for inheritance does not establish that genes are the source of biological agency, the basis of biological normativity, or the primary explanation for the existence of living systems. The question is not whether genes matter, but what role they play within the larger organisation that makes inheritance, adaptation, and evolution possible.

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 reproduces continuity across generations
• variation modifies that continuity
• fitness reflects differences in the continuity of lineages of organised persistence selection differentially stabilises those differences through time
• selection differentially stabilises those differences through time

evolution is therefore:

the historical transformation of viability-oriented organisation across scale

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

Genes Within Biological Organisation

Genes occupy a central position within APS because they contribute directly to the continuity and transformation of lineages of organised persistence. Genetic systems help stabilise constraint organisation, support the transmission of viability-relevant structures across generations, and provide mechanisms through which variation can be introduced into evolutionary processes. In this sense, genes are indispensable participants in inheritance and evolutionary transformation.

Yet genetic processes are always embedded within a broader organisational context. Gene expression depends upon cellular organisation, metabolic activity, regulatory networks, and environmental conditions that the living system actively maintains. The replication of DNA, for example, requires extensive physiological coordination and cannot occur independently of the organismal processes that sustain the conditions under which replication becomes possible.

This reciprocal relationship is crucial. Genes contribute to the maintenance and transformation of biological organisation, but biological organisation simultaneously regulates the conditions under which genes exert their effects. Genetic causation is therefore neither autonomous nor isolated. It operates within a larger continuity-producing architecture that includes development, physiology, behaviour, and organism–environment interaction.

From an APS perspective, genes are best understood as mechanisms within ongoing biological organisation rather than as sovereign drivers of life. Their significance derives from their participation in the processes through which lineages of organised persistence reproduce continuity, generate variation, and undergo evolutionary transformation through time.

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:

• fitness reflects differences in the continuity of organised systems, and natural selection differentially stabilises those differences among lineages of organised persistence.
• 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.
