Fig. 6: Echolocation analysis.
From: Evolutionary sparse learning reveals the shared genetic basis of convergent traits
The topology of species used in the echolocation analysis is depicted in a cladogram, which is derived from the consensus species tree of mammals59. Echolocation evolved twice in mammals in this phylogeny. Therefore, two contrast pairs can be constructed (e.g., solid blue branches, echolocating; solid red branches, non-echolocating). A series of 15 comparable sets of input pairs can be constructed by including alternative sibling species (dotted blue and red species) in all possible combinations. Species not included in the contrast pairs do not affect the analysis (black dotted branches). Shared ancestry is canceled out (gray dotted branches). Only a subset of the species not used in the analysis are depicted here to highlight the phylogenetic context.
