Fig. 3: Molecular dating of early Y. pestis.
From: Neolithic Yersinia pestis infections in humans and a dog

Maximum clade credibility tree based on 42 modern and ancient Y. pestis genomes and the two genomes from Warburg (red). All dates are given as calibrated years before the present (cal BP). Country abbreviation is provided in brackets as described in Fig. 2. Genomes included in the molecular dating analysis are listed in Supplementary Data 6.
