The allometric relationship between brain and body size in canids (IMAGE)
Caption
The allometric relationship between brain and body size in canids. Points are species-specific estimates of bady mass and brain volumes observed in 25 canid species and the line defines the expected relationship between these based on the evolutionary model. The domesticated dog is highlighted with filled point (that shows the mean trait values across 11 ancient breeds). The data point for the common raccoon dog that is the only canid species that hibernates is labelled with its scientific name and shows that this species has the smallest brain size as expected from its body size.
