Persistence hunting is pursuit until the prey can no longer flee and succumbs to exhaustion or heat stroke. History and definition Some researchers have insisted that the point of persistence hunting is not to induce exhaustion but specifically to induce heat stroke. However, a decade later, they understood persistence hunting to include pursuit until injury or heat stroke or exhaustion; and driving prey to ambushes, natural traps like cliffs and rivers and ravines, or man-made ditches and stakes. There do not seem to be descriptions which take account of heat dissipation theory. Hunters Startled animals respond in characteristic ways that may be effective against animal predators. People learn how prey respond and plan (and prepare themselves) to overcome that response. They learn how to monitor their own condition and stay within their limits, while pushing the prey animal beyond its physiological limits. Research and discussion about persistence hunting has often been in the context of providing reciprocal support for the Endurance running hypothesis. However, hunts are not intended to be a fair contest of endurance. On the contrary, hunters use their knowledge to put the prey animal at every disadvantage. Even proponents "agree that persistence hunting is not practiced by the Hadza and only rarely by Bushmen and other foragers". Cheetahs as prey Cheetahs near Wajir were preying on Mr Hassan's goat herd each morning. He waited a few hours until the hottest part of the day, when Cheetahs typically rest in the shade. Mr Hassan and 3 youths chased about until they captured the 2 cheetahs. Cheetahs at hunt have exceptional speed, acceleration and deceleration — for a few seconds. A typical chase only lasts a minute and exhausts the cheetah so much that it is forced to rest. On a typical day a cheetah would make a single chase covering 200 to 500 m. Deer as prey In Copper Canyon once fresh tracks were found, the deer were chased into a trap and clubbed. Either a natural trap: a river, cave, ravine, cliff or rocky ground to injure the animals' hooves; or a man-made trap of sharpened wooden stakes set into the ground and hidden with leaves. In other words the Rarámuri commonly planned and prepared game drives. Less commonly the deer were tracked and chased to exhaustion. The hunters walked and ran at a "steady pace", a gradual jogging pace. They prepared by drinking pinole and eating
