The Clan of the Cave Bear (Earth's Children, #1)

by Jean M. Auel

The Clan could not conceive a future any different from the past, could not devise innovative alternatives for tomorrow. All their knowledge, everything they did, was a repetition of something that had been done before. Even storing food for seasonal changes was the result of past experience. There had been a time, long before, when innovation came easier, when a broken sharp-edged stone gave someone the idea to break a stone on purpose to make a sharp edge, when the warm end of a twirled stick made someone twirl it harder and longer just to see how warm it could get. But as more memories built up, crowding and enlarging the storage capacity of their brain, changes came harder. There was no more room for new ideas that would be added to their memory bank, their heads were already too large. Women had difficulty giving birth; they couldn’t afford new knowledge that would enlarge their heads even more. The Clan lived by unchanging tradition. Every facet of their lives from the time they were born until they were called to the world of the spirits was circumscribed by the past. It was an attempt at survival, unconscious and unplanned except by nature in a last-ditch effort to save the race from extinction, and doomed to failure. They could not stop change, and resistance to it was self-defeating, antisurvival.
