We behave like primates

Games Primates Play: An undercover investigation of the evolution and economics of human relationships by Dario Maestripieri.  If you are interested in in behavioral finance, you should read this work on evolutionary development. We are not that far from our primate brothers. Humans engage in dominance behavior like primates. Some try and become the alpha being. As such, there is social climbing of the ladder. Humans will engage in nepotism no different than primates. We will engage in cooperative behavior similar to primates. While the link with trading is not direct, we have to accept our primate root and our human relationships are  not that different than our primate cousins.
