- The branching points of the cladogram may be regarded either as an ancestral species ( as in an evolutionary tree ) or solely as representing shared characteristics
在这个形象化的进化树上，每两个物种间的距离都是由它们共有的特性来决定的。 - ( 3 ) in the molecular cladogram , euchiloganis forms a sister group with pareuchiloglanis , and pseudecheneis forms a sister group with glyptostemum - , the phlogenetic positions of pseudecheneis and exo
因此，石爬跳属鱼类划分为一个种更为客观，黄石爬排为青石爬跳的同物异名。 - The cladogram proposed in the present paper also suggests that the maniraptoran troodontidae and ovkaptoridae should have the branched feathers , and that feathers evolve and initially diversify in terrestrial theropod dinosaurs before the origin of birds and their flight

结果表明： ( 1 )环区平均变异位点较茎区多，有很强的a偏好性； ( 2 )没有替代饱和现象； ( 3 )分子系统树上?属和纹胸?属构成姐妹群，石爬?属和?属构成姐妹群， ?属和原?属构成姐妹群； ( 4 ) ?属、原?属和褶?属的系统发育位置不定， ? ?鱼类并未形成一个单系类群；可能的原因是所得到的16srrna基因片段信息位点太少； ( 5 )青石爬?和黄石爬?可能是同一物种，中华?和前臀?可能是同一物种。 - The cladogram shows that the opatrini of 14genera in china is not a monophyly , mesomorphus is a monophyly , and another monophyly is composed of others 13 genera . and according to the faunal analysis , we can conclude that opatrini in china is mainly distributed in palaearetic region , hi which the number of genera makes up 59 . 1 % ( 13 genera ) of the total , including 50 % ( 11 genera ) in middle asian subreahn , which combined with distribution of this tribe in the world , so it is proposed that the middle asian subrealm can be viewed as the core of distribution . most of genera distributed in limited area , only gonocephalum distributed in extensive area
根据已知种类，对世界和中国范围内土甲种类的区系组成和地理分布特征进行了首次分析，结论为：世界土甲族以西半球最丰富，古北区最多，其次为非洲区；我国土甲的主体成分是古北区种类，共有12属( 54 . 5 ) ，其中11属( 50 )分布于中亚地区，据此认为我国土甲在区系组成上以中亚成分为主；我国除土甲属gonocephalum广泛分布外，绝大多数属均为狭域分布；蒙新区和华南区的特有属较多，说明中国土甲族具有中亚起源和热带起源两种可能；物种数量分布以蒙新区最多，华南区其次，呈现两极分布格局。
