腹足类系统发育及分类学研究现状

The research status of Gastropoda phylogeny and systematics

现已证实腹足类是系统进化研究很好的材料,其优越性是其他动物类群难以取代的,但腹足类仍然没有被很好地用来进行系统进化研究。腹足类单源说得到多数研究人员的认同,但还需进一步考证。虽腹足类系统发育及其分类学研究有了很大的进展,但目前对腹足类的自然分类系统尚有不同的见解和看法,诸多研究工作还有待开展,其较长的进化历史、快速辐射演化、趋同进化、趋异进化等因素使腹足类的系统分类学面临挑战。通过回顾腹足类系统发育、分类学研究现状和其中较有影响的分类过程,并对肺螺类系统发育及分类现状进行了综述。

Gastropod is a perfect kind of objects of evolutionary studies with an opportunity that no other animal group can offer in the same way. But these creatures have not been studied in the evolutionary researching field. The monophyly accepted by most of the specialists of gastropod morphology but requires further testing. Gastropod phylogenetic systematics has seen a recent boost from the end of last century. At the same time, there is not a consistent opinion on gastropod taxonomic. Much more research work needs to be done in the future. Gastropod phylogenetic systematics is confronted with a challenge induced by the long evolutionary history, the often-rapid radiations, convergent evolution and divergent evolution. This paper reviews the status of Gastropod phylogeny and systematics, especially comments on the Pulmonata, Stylommatophora.
