Is the Paleolithic diet 10,000, 100 or 15 years old?

They say there are no new ideas. Paleo - primal like diets have been around in one form or another for a long, long time. Listed below are some examples up until the year 2000 - after that much has been written.

Banting (1864). A letter on corpulence.
A smallish book on how to lose weight written by a grateful patient, given away and then priced at cost.
( While not pure paleo, the diet was in a paleo like direction ie consisted of natural meats, fruits, vegetables with dairy and grains excluded and small amounts of dry grape wine permitted (ie low sugar wine).
