The Bishop–Cannings theorem is a theorem in evolutionary game theory. It states that (i) all members of a mixed evolutionarily stable strategy (ESS) have the same payoff (Theorem 2), and (ii) that none of these can also be a pure ESS (from their Theorem 3). The usefulness of the results comes from the fact that they can be used to directly find ESSes algebraically, rather than simulating the game and solving it by iteration.
Evolution of species is a two way theorem,horizontal and vertical.Evolution takes place that way.All the species evolved from the junction of the two.Vertical is a tree.Horizontal indicates all species from prokaryotes to humans were created at once.Humans existed from the nodal center even.
