Biopathocodicology?? 🦠🧬🐑 (1/4) Check out this groundbreaking new #aDNA #pathology paper by @louis-lhote.bsky.social @gingerhowley.bsky.social and colleagues! www.biorxiv.org/content/10.6...
Phylogenetic and dating analysis of ancient and modern sheeppox virus. A. 
Maximum-likelihood phylogeny of ancient and modern SPPV genomes with ≥5× coverage, rooted 
using LSDV and GTPV. Nodes with bootstrap support of 100 are indicated by blue circles; other 
bootstrap values are shown at the corresponding nodes. Clades composed exclusively of modern 
genomes are collapsed and shown as triangles, and branches corresponding to ancient genomes are  highlighted in pink. The grey box delineates the SPPV clade. B. Maximum-likelihood phylogeny of 
SPPV genomes with placement of low-coverage ancient samples using PathPhynder (Martiniano et 
al., 2022). For clarity, only the SPPV portion of the phylogeny is shown. Samples are coloured by 
material type, and low-coverage genomes (<5×) placed using PathPhynder are indicated by red 
triangles. Nodes with bootstrap support of 100 are marked with blue circles; other values are shown at  the corresponding nodes. Tip labels indicate sampling location and calibrated historical date. Host 
species, sequencing coverage, and sample age are shown as a heatmap adjacent to the tips. C. 
Time-calibrated Bayesian phylogeny of the SPPV clade, with samples coloured according to material  type.
