Fig. 1.

A bifurcation for a signaling game with two signals under the selection mutation dynamics. The game shows a fragment of the full state space with two sender strategies and three receiver strategies. Dots indicate rest points. Black dots indicate asymptotically stable rest points and white dots indicate unstable rest points. In A the ratio $\delta /\epsilon$ is sufficiently large (including the case $\delta =\epsilon$) so that orbits converge to one of the two signaling systems from almost all initial conditions. However, in B, one rest point close to the upper boundary of the state space is asymptotically stable; hence, some orbits converge to this rest point and not to the signaling systems.
