Phylogenetic tree of T. leucocephalus and 15 other primate species. A maximum likelihood tree based on 5345 orthologous proteins was generated and used to infer the expansion and contraction of 9906 gene families. The numbers of expanded and contracted gene families are shown in green and red, respectively. The estimates of divergence time are shown in blue. The number by the most recent common ancestor (MRCA; at the root of the tree) indicates the bootstrap evidence for partition based on 1000 bootstrap replicates
