  1. Mutation rate references: (1) One substitution per 5,139 years [56]; (2) One synonymous transition per 6,764 years [36]; (3) One synonymous mutation (transition or transversion) per 7,884 years [35]. Founder Age: ρ = 12,8; σ = 1.6 with the Mishmar and colleagues approach [56], and ρ = 9.2; σ = 1.36 with the Kivisild and colleagues [36] and Soares and colleagues [35] approaches. TMRCA, 95% confidence intervals (CI), and founder age are given in years.
