Can someone please explain this passage to me, 'The “mating mind” sexual selection hypothesis seems at odds with this density effect, and with the more general fact that polygamous species tend to have smaller brains.' My intuition is that the density effect would accelerate brain growth if big brains are sexually selected for, as it would provide more mating partners for the largest brained males.
