Phylogenetic systematics is a relatively new formal technique that increases the precision with which one can make direct estimates of the history of phylogenetic descent. These estimates are made in the form of phylogenetic trees, or cladograms. Cladograms may be converted directly into classifications or they may be used to test various hypotheses about the evolutionary process. More than 20 phylogenetic analyses of helminth groups have been published already, and these have been used to investigate evolutionary questions in developmental biology, biogeography, speciation, coevolution, and evolutionary ecology.
系统发育系统学是一种相对较新的形式技术，它提高了人们直接估计系统发育谱系历史的精度。这些估计是以系统发育树或分支图的形式进行的。分支图可以直接转化为分类，或者可以用来检验关于进化过程的各种假设。关于蠕虫类群的20多项系统发育分析已经发表，这些分析已被用于研究发育生物学、生物地理学、物种形成、协同进化和进化生态学中的进化问题。
