(p. 42) Judging from slowly changing styles of stone axes, innovation was rare and technological change almost imperceptible. The rhythm of daily life varied little from one generation to the next, just as the lives of animals followed predictable and familiar paths of migration and dispersal, life and death. Humans were collaborative predators among predators, both hunters and the hunted, effective at survival thanks to their expertise with wooden spears, their stalking ability, and their painfully acquired knowledge of animals and plants. And, over two hundred millennia, they gradually evolved into the Neanderthals, the primordial Europeans encountered by the Cro-Magnons.
