Posted by: RSNewton at Wed Aug 13 22:21:06 2003 [ Email Message ] [ Show All Posts by RSNewton ] BTW, Tong et al. (2002 Acta Zoological Sinica) include at least 2 racers among their colubrids, namely Zaocys and Ptyas. Both of these species are also sequenced by Lopez and Maxson (1995). Tong et al. and Lopez and Maxson both find that the ratsnakes (Elaphe) are more closely related to each other than they are to either Ptyas or Zaocys. Ptyas is clearly the outgroup to all of the species in Utiger et al.'s study. If their data only support this outgroup status weakly, then there is something wrong with their data. | ||
