Figure 2From: Molecular evolution of UCP1 and the evolutionary history of mammalian non-shivering thermogenesisUCP species tree. Thick branches are Eutherian lineages for each respective gene. The values above each Eutherian branch are branch length estimates from the M0 model. Three letter species codes are given at the tip of each lineage. Species names can be found in Supplementary Table 1.Back to article page
