英文
ancylus fluviatilis-
Robustness of our results was confirmed by high bootstrap support of all nodes in the trees. this result contradicts the batrachia hypothesis ( a salamander + frog grouping ), and is consistent with bolt ' s hypothesis ( 1991 ) basing on the morphological data. the result was also supported by previous molecular studies based on mitochondrial and nuclear rrna data
這個結果與蛙類假說是相矛盾的，與bolt （ 1991 ）中國澤蛙線粒體基因組結構及種群系統地理學研究在形態學基礎上提出的絨蝶類和蚓螺類為姐妹群關系的假說相一致，並得到建立在線粒體和核trna基因數據基礎上的許多分子研究的支持。Away from this cirrus shield, some low - level spiral cloud lines can also be clearly seen
