Temporal haplotype network for historical Finnish wolves. Each circle represents a different haplotype whose names are given next to the circles in the bottommost layer. Number of individuals bearing each haplotype is given within circles. White circles denote missing haplotypes for that time period. Number of dots +1 connecting haplotypes equals to nucleotide differences. Maximum evolutionary divergence (i.e. base substitutions per site) was 0.055 (OW36–OW102) and minimum 0.003 (OW40–OW17/OW37/OW104).
