And what else than something we needed and craved would force us into
hunting and gathering from something as unpredictable and dangerous as
the sea? Early man did harvest seaweed, sea vegetables, crabs and fish
from the sea.
Salt is so important to the human diet that it eventually became a
staple of early trade and a form of "money". Also was used for meat
preservation. Other animals crave salt too, hence the "saltlick". Our
pets lick it from our skin when we are sweaty.
My guess is that our paleo ancestors grabbed salt whenever they could
from whatever source they could find (dried seabeds, sea vegetation and
seafood).
