  1. Numbers in brackets are the r2 values of the regressions and asterisk and bold font indicate significant regressions (significance levels are Bonferroni corrected to account for multiple testing). Breeds of domestic dogs are ordered according to length of investigated time period (years), from longest to shortest (Table 2). For descriptions of skull dimensions see Table 1
