Bull TerrierCloseness is measured from the genomes, and nothing else. It has no units and no dates. Two breeds sitting close together means their lines separate late in this data. It does not mean either one came from the other.
5 sequenced dogs is a thin sample. This breed’s exact neighbours could move if more were added; the neighbourhood is steadier than the order within it.
