How Humans Outran Gazelles in the Desert
Human energy expenditure and thermoregulation during persistence hunting in the Namib.

Surprising Findings
Hunters didn’t need to run to succeed—especially with injured prey.
Most assume persistence hunting means nonstop running until prey collapses. This shows it’s more about patience and exploiting prey vulnerability.
Practical Takeaways
Use pacing and patience over intensity to conserve energy in extreme heat.

Even in extreme desert heat, humans didn’t overheat while chasing antelopes, but the antelopes did overheat and collapsed from heat stress.
Even though they were sweating a lot in the scorching desert, the hunters didn’t lose so much water that they were at risk of dying from dehydration.
People running after antelopes in the desert for hours got way more energy from the hunt than other ancient food-gathering methods, making it a very efficient way to get food.
People didn’t need to run the whole time to catch antelopes—sometimes they just walked, especially if the animal was already hurt.
People who hunt by running all day in the desert burn a lot of calories and lose a lot of water—but not so much that they get dangerously dehydrated, similar to other desert-dwelling hunter-gatherers.
