Posted by: hermanbronsgeest at Tue Oct 9 08:42:52 2007 [ Email Message ] [ Show All Posts by hermanbronsgeest ] The problem with Burbrink et al's proposal, is that the only Pituophis species sampled is the apomorphic ('advanced') P. melanoleucus. Plesiomorphic ('primitive') species like P. deppei and P. lineaticollis are not examined. Based on the information provided by Burbrik et al, it is therefore impossible to determine exactly where the Pine Snake lineage splits off. Whether or not Cornsnakes and Great Plains Ratsnakes should be included in Pithuophis cannot be answered by this study. Therefore the proposal cannot possibly get accepted. [ Hide Replies ]
