文摘Pseudogene and fibrin peptide which has rapid evolve speed and good stability are used in this study to determine the divergence date among groups.Through calculating the evolutionary rate of hemoglobin α chain,γ chain in vertebrate（including birds and mammals）,it is concluded that the evolutionary rate of hemoglobin α chain,γ chain is not invariable.It shows different evolutionary rates in different periods,that is,faster in early evolution stage and relatively slow in later stage.
