Fig 1.
An evolutionary tree representing the 15 domesticated mammals (indicated with gray terminal branches) and their closely related wild relatives (indicated with black terminal branches) that were studied.
The tree is based on multiple genes, as described in Upham et al. 2019. The tree was obtained as a “phylogeny subset” from the VertLife website (https://vertlife.org/data/). See text and S2 Table for species names. All mammal silhouettes were taken from http://phylopic.org and are under a public domain license. The pertinent information concerning each silhouette is available as a S1 File).
