Interne und eingehende Aktivitäten advent of genetic sequencing. For example, the phylum Annelida was traditionally divided into three classes, Polychaeta (bristle worms), Hirudinida (leeches), and Oligochaeta (earthworms). It is now widely recognized that Hirudinida is nested within Oligochaeta, making the latter group paraphyleticCHOKE 发表于 2025-3-23 03:05:29

A particular complication is the seasonal changes in the numbers, dem
