Median joining network of genetic variation at a 335 bp fragment of the mitochondrial control region in 693 red foxes. 35 ancient samples from Teacher et al. [25] and one modern sample from Valière et al. [28] were excluded due to their shorter sequence length. White: Nearctic lineage haplotypes; grey: Japanese haplotypes (all Japanese lineages); black: Holarctic lineage haplotypes, except for North American, Japanese and central Siberian haplotypes; black with white circle: North American haplotypes (Holarctic lineage); black with white stripes: central Siberian haplotypes (Holarctic lineage).
