7V. From site: Durc was a mixture of both Neanderthal and Modern Man -- "Figuratively, Durc was the only son of the Clan. After Creb saw a glimpse of the Clan's doom at the Clan Gathering, Creb came to believe that Durc was Ayla's gift to the Clan. Children like Durc (and their descendents) would carry on some part of the dying Clan." There are implications, both in "Clan of the Cave Bear" and in Ayla's dreams in later books, that Durc will become the future leader.
