A horse pacing a fence line, calling repeatedly when stabled alone, planting at a gate, or seeming hypervigilant on a hack can look difficult or unpredictable. The idea of a teleonome offers another way to ask why a horse behaves this way: consider the animal as an integrated organism responding to its environment, rather than treating one behavior or measurement as a complete explanation.
In a 2026 conceptual paper, the teleonome is the integrated system of perceptual, physiological, behavioral, and affective capabilities through which an organism pursues biological goals in changing conditions. It can help organize how we interpret welfare evidence, but it is not a diagnosis, a training method, or a rule that by itself determines what humans ought to do.

What is the teleonome?
The teleonome is a proposed biological framework for understanding how an animal detects and values circumstances, regulates itself, and acts in relation to its surroundings. It brings together an organism’s evolved capabilities and the opportunities and constraints its environment provides.
For horse welfare, this shifts the question from “What does this behavior mean on its own?” to “What might this horse be responding to, and how does this response fit with its needs, capacities, and circumstances?” A behavior, physiological reading, or affective assessment is evidence to interpret—not a self-explanatory verdict.
#1 Best Overall
Wilkins and co-authors introduce the framework in a hypothesis-and-theory paper published in Frontiers in Animal Science on February 25, 2026. They describe the teleonome as an integrative concept for connecting adaptive capabilities, affective regulation, agency, and environmental affordances. It is a conceptual proposal, not a validated horse-specific scoring instrument or clinical test. Read the paper in Frontiers in Animal Science.
Telos, teleonomy, and teleonome: what is the difference?
The terms describe three related but distinct levels of explanation:
| Term | What it refers to | How it helps explain welfare |
|---|---|---|
| Telos | The biological goals of viability, survival, and reproduction. | Names the goals an organism’s biological systems are organized around. |
| Teleonomy | The principle that goal-directed biological organization arises through natural selection. | Explains how evolved organization can produce apparently goal-directed responses without implying conscious planning. |
| Teleonome | The integrated system of traits and regulatory processes through which an organism pursues those goals in relation to its environment. | Focuses on the organism as a whole: its capacities, responses, and interactions with its surroundings. |
Put simply, telos names biological goals, teleonomy describes their evolved organization, and teleonome names the integrated system pursuing them. The distinction matters because a goal-oriented biological explanation is not the same thing as a moral instruction.
How can this framework change the way we interpret horse behavior?
In Cristina Wilkins’s explainer, behaviors people might call “vices,” separation anxiety, nappiness, or character flaws become prompts to investigate context rather than labels that settle the explanation. Wilkins’s explainer in Horses and People uses examples including pacing, repeated calling, reluctance at a gate, and heightened vigilance. None of those signs alone proves a particular emotion, cause, or welfare condition.
Pacing or calling when alone
Consider the horse’s social and housing conditions, what changes when it is separated, and what options it has to respond. These behaviors may be relevant to how the horse is experiencing its circumstances, but they do not establish a single cause without further assessment.
Planting at a gate
Reluctance at a gate is a reason to look at the situation around that point: what the horse encounters there, what it may be motivated to approach or avoid, and what its environment makes possible. Calling it “nappy” describes a human interpretation, not an explanation of the horse’s experience.
Hypervigilance on a hack
Heightened vigilance should be understood in context, including the surroundings and the individual horse’s adaptive capacities. The visible response can inform an assessment, but it cannot by itself tell you exactly what the horse feels or why.

A measure matters only when its relationship to the animal’s biological and lived circumstances is understood. The framework cautions against reading an isolated number or observation as if its meaning were obvious:
- A lower physiological measure does not automatically prove that a horse is calm.
- High arousal does not automatically show that a horse prefers the situation.
- No measured change does not demonstrate that there was no welfare effect.
Instead, interpretation should connect behavioral, physiological, affective, and environmental evidence with the horse’s motivation, individual capacities, and the conditions it is responding to. The point is not to discard indicators, but to ask what they mean for this animal in this context.
Does the teleonome define good welfare?
No. The teleonome is descriptive: it helps explain how biological systems support goal-directed life and why affective experience can matter to an animal’s responses. It does not prescribe what welfare ought to be. Wilkins and co-authors state that affective experiences help animals detect relevance, prioritize competing demands, and modulate behavior and physiology over time; that explanation does not, on its own, decide which conditions humans should provide.

Nor does an evolved response necessarily benefit the horse in every present-day setting: evolutionary function is not the same as happiness, and survival or reproduction alone cannot settle ethical questions.
Quick Recap
What to take away
- The teleonome is an integrative biological concept, not equipment, a training product, or a standalone test.
- It connects an animal’s perceptual, physiological, behavioral, affective, and adaptive capacities with its environment.
- Its practical value is to prompt contextual interpretation of welfare evidence, not to assign a cause or diagnosis from one sign.
- It complements empirical assessment; it does not replace veterinary care or the ethical reasoning needed to decide what good welfare requires.
