Phylogeny trees of tumour-related sequences in primates. Trees were constructed with the neighbor-joining method using pairwise deletion and tested with 1,000 bootstrap replicates, (a) Phylogeny of the AL040372-homologous sequence, which demonstrates a divergence of 8% ± 1.4% between Homo sapiens and Lemur catta. (b) Phylogeny analysis of the AA166653-homologous sequence. The maximum divergence in this cluster between Homo sapiens and Pongo pygmaeus is 7.8% ± 1.1%, and the divergence between Homo sapiens and Pan troglodytes is 4% ± 0.3%. (c) Phylogeny of the AI792557-homologous sequence among primates. The maximum divergence between Homo sapiens and Ateles fusciceps is 14.6% ± 1.3% for this sequence, (d) Phylogeny of the AI952931-homologous sequence among primates. The sequence divergence ranges from 0.9% to 7.8%. It was found that Homo sapiens and Pan troglodytes have 1.2% ± 0.4% divergence; the divergence between Homo sapiens and Callimico is 7.8% ± 1.2%.
