Coevolution between seasonal/yearly breeding and diet in mammals. Transitions can occur between four states: yearly reproduction and carnivory (left upper)/herbivory (left lower)/omnivory (right), seasonal reproduction and carnivory/herbivory/omnivory, yearly reproduction and non-carnivory/non-herbivory/non-omnivory, and seasonal reproduction and non-carnivory/non-herbivory/non-omnivory. Arrows indicating transitions between states are scaled to represent the probability of a transition: line thicknesses are proportional to transition rates. Absolute values of transition rates (per million years) are indicated next to each arrow.
