Phylogenetic tests of positive selection in primates.

aCodons identified by more than one ML method are underlined.bps = proportion of the sites under selection, ωs = estimated dN/dS of the sites under selection in M8.cPositively Selected Codons: only the codons identified by at least two of the ML methods were considered to be positively selected codons.a. 被不止一种最大似然（Maximum Likelihood, ML）方法鉴定得到的密码子已添加下划线。 b. bps指代受选择位点的占比，ωs指代模型M8中受选择位点的非同义替换速率与同义替换速率的比值（dN/dS）估计值。 c. 正选择密码子：仅将被至少两种最大似然方法鉴定出的密码子认定为正选择密码子。
