"The Others" is a name given to the Cro-magnon race by the neanderthals. Almost everybody mentioned in the books is one of "The Others" with the exception of the Clan people introduced. Essentially a person of the "Others" is not a person of the Clan. Ayla did not consider herself one of "The Others" for a significant portion of her life identifing herself as "Clan" despite her obvious Cro-magnon build and features. Instead of recognising the different "people" or tribes, The Zelandonii, the Mamutoi and so on they group all of them together as "The Others".
