I am working on a review aricle on evolution of surgical sense in human.Zoopharmacognsy knowledge in lower mammals and apes were well utilised by early "H.sapiens" for medicinal treatment of their ailments -- which ultimately sprouted up into primitive medical therapy. Earliest surgical experise in man -- as accepted today -- was "Trepination" in skull -- a practice which was not known to late Primates / Apes. I am intersted to know what were the "surgical" counterparts to "zoopharmacgnosy". Was their any? -- dr.n.k.majumder.
