Bartering - the action of exchange by which both parties recieve goods. Thus money in exchange for goods is by definition bartering. Its survival of the fittest at its best, if you have something better than me then I would naturally want it, if I have something better than I would not be willing to exchange it.
"I think that the point is, just as we are close to our cousins physically we are also close to them in some of the underpinnings of your mind as well. There is a continuum."
If you had read my post properly you would have seen that my general point was that we are close to our "cousins" and this is why we study them, in oder to understand early human behaviour.
Your point of view is interesting none the less
