Cartographies of the exodus: migration as an evolutionary engine
I Seventy kilometres of jungle
In 2023, 520,000 people cross the Darién Gap. There is no road: 70 kilometres of jungle between Colombia and Panama, five to ten days on foot. It is the only land discontinuity in the Pan-American Highway, and it has become its busiest stretch.
A cartographic void working as the main corridor. The absence of infrastructure is the infrastructure.
“The road was not there. Feet made it, and now it shows up on the maps.”
II Anatomy of the movement
Deleuze and Guattari distinguished the migrant, who goes from one point to another, from the nomad, who occupies the space between the points.
The contemporary exodus is neither, and that is the novelty. It has a declared destination, like the migrant; but the journey lasts years and produces its own cities, economies and languages, like the nomad.
I would call it a third state: the transit that lasts longer than the stay.
III Table of what a corridor generates
| Appears along the route | Scale |
|---|---|
| an economy of guides and transport | 1,700 USD per person |
| charging and connectivity points | every 15-20 km |
| a lexicon of its own | dozens of terms |
| cartography shared by messaging | updated daily |
None of those four was planned by a state. All four work. An exodus corridor produces more institution per kilometre than many official borders.
IV The biological turn
Here the critique changes discipline, and it is worth saying why.
In thermodynamics, mass displacement reads as dissipation: energy lost, human labour burnt on the move. It is a correct description and it explains nothing.
In biology it reads differently. Gene flow —the movement of individuals between populations— is what stops a population settling on a local optimum and dying when the environment shifts. A species with no migration is not a stable species: it is a species on hold.
This is no consoling metaphor. It is the only frame in which movement appears as a function and not as a breakdown.
V Risks
And here you have to brake hard, because the evolutionary analogy has an edge that cuts the wrong way.
Reading migration as an engine can become an elegant way of justifying what produces it: if the movement is functional for the species, the misery that drives it is converted into an input. That is obscene and it is also false — nothing in the biology of gene flow requires the journey to kill anyone.
The analogy serves for thinking about migration. It does not serve for thinking about the Darién. For that you need figures of responsibility, not of evolution.
VI Coda
If maps are drawn where people pass, and not the other way round, then borders are not lines: they are bets on where nobody will pass.
And every year that bet is lost across seventy unpaved kilometres of jungle, which already appear on the maps because half a million people insisted on walking them.
