All human hunter-gatherer groups that have been studied incorporate meat in their diets. Studies have shown that the total dietary contribution of meat varies a great deal, and seems to increase with latitude so that foragers in subarctic and arctic regions eat a lot of meat while those living near the equator eat less. It is probably true that tropical and subtropical foragers obtain more of their calories from plants than from meat over any reasonable amount of time. The meat consists primarily of mammals for most groups, but fish, birds, reptiles, and invertebrates can reach high proportions, especially seasonally. Most forager groups make use of dogs in their meat acquisition, and it may well be the case that dogs are as important in the forager tool kit as any projectile, spear, or butchering tool.
