Ayla was probably based on the character Ayla (an Ice Age-era woman) from Jean M. Auel's series of prehistoric novels, Earth's Children. The best known among these is likely The Clan of the Cave Bear. I'll admit I've never read any of these, but the link seems fairly apparent. If Ayla isn't consistent with the Japanese name, then we likely have Ted Woolsey to blame.Originally Posted by Martyr
