5HC Gondwanaland

As Jack Vance is and was a major unfluence on GW, the idea in 5HC of prehistoric human migrations from Earth to other worlds may have been picked up, in part, from certain Vance novels of the Sixties: THE STAR KING, SPACE OPERA, and the Tschai series. However implausible the concept, Vance used it repeatedly. --Nick Gevers.
