In the later study by Arnason and colleagues, two independent nonprimate molecular references were used. These two references suggested that the Cercopithecoidea/Hominoidea divergence took place >50 mya. Also, all hominoid divergences receive a much earlier dating. Thus, the estimated date of the divergence between "Pan" (chimpanzee) and "Homo" is 1013 mya and that between "Gorilla" and the "Pan"/"Homo" linage approximately 17 mya. The same datings were obtained in an analysis of clocklike evolving genes.
