Somewhere in Africa or Asia a band of unusual apes leaves the safety of the trees in the early morning light and stealthily approaches a grassland waterhole. A wounded antelope is sighted and the males, approaching quietly from all sides, spring to action. The thrashing animal is quickly subdued with rocks and clubs. Chunks of meat are ripped from the carcass and the band quickly retreats to the forest. All eat well and they multiply. The weapon using primate had arrived – the ancestor of homo sapiens.
The above scenario depicts what some of the best evidence of biology and anthropology suggests concerning the origin of man. The evolutionary forerunners of homo sapiens probably diverged from primitive ape stock in becoming co-operative, systematic carniverous users of weapons. Perhaps modern man would not have evolved had it not been for this development, and the most highly evolved primate of the modern age would have been arboreal, primarily vegetarian apes.
