You wake up, commute, sit, stare at a screen, and repeat. No predators. No famine. No immediate danger. So why does your body feel under siege by 3 PM?

The answer may lie in the shape of modern work. Evolutionary psychology suggests offices violate ancient rules our nervous systems still follow. But is this science—or just a compelling story?

The Myth of the Lazy Ancestor

First, let’s dispel a fantasy. Hunter-gatherers didn’t lounge around—life demanded constant effort. The difference wasn’t whether they worked, but how. Tasks shifted with the environment, tied to tangible outcomes. Modern work often severs action from visible consequence.

The Science of Control (Or Lack Thereof)

The Job Demand-Control-Support model shows high stress arises from high demands and low control. This aligns with evolutionary psychology: our stress systems evolved for actionable threats, not abstract ones like emails or deadlines.

The Chair as a Biological Mismatch

Sitting for hours may violate how our bodies evolved to move. Ancestral humans walked, crouched, and rested in bursts. Modern work turns movement into an appointment.

Belonging: The Ancient Social Contract

For ancestral humans, belonging was survival. Modern workplaces often strip away visibility. Contribution becomes abstract, and effort feels like shouting into a void.

Evolutionary Psychology: Science or Story?

The field faces criticism for "just-so stories." But modern research uses cross-cultural data and genetic evidence. The truth? It’s evolving—but not settled.
