In my 1980 sf novel THE DREAMING DRAGONS, Saurus sapiens lived on pre-freeze
Antarctica and didn't roam beyond its shores because they evolved Vingean
Tine-like group minds, connected via radio so that you got stupid fast if
you roamed too far from the pack. Individual brains were, so to speak,
terminals. A kind of trace immortality was built in to their distributed
consciousness.
