Memories, sometimes referred to as Clan memories, are a form of racial memory; the way Neanderthals pass on knowledge from generation to generation. A child of the Clan is born with memories and only needs to be 'reminded' of something once before they remember it permanently. The need to encode everything into a child's brain has increased the Neanderthal head size so large that by the time of The Clan of the Cave Bear, women of the Clan are having trouble giving birth.

Some children of mixed spirits also possess racial memories.
