Turbellarians are relatives of the major groups of parasitic platyhelminthes - monogeneans, digeneans, and tapeworms - and most are free-living. Because the ancestors to the major parasitic groups would be classified as turbellarians, strict application of princi ples of phylogenetic systematics dictates that the Turbellaria is not properly considered a separate taxon; i. e., it is, in the parlance of systematics, a paraphyletic group. The relationships of turbellarians to other inver tebrates are even more problematic than their relationships to other platyhelminthes; their relatively simple morphology has been variously interpreted as quintessentially primitive - meaning a turbellarian-like ances tor would have given rise to most of the major groups of invertebrates - or as secondary simplification, meaning they would essentially be a dead-end group. Modern research on turbellarians covers a broad spectrum. Questions of phylogenetics have inspired ultrastructural studies; the simply structured nervous systems of turbellarians make them good subjects for neurophysiology; simplicity of their tissue structure and the limited number of cell types make them good subjects of embryological and regeneration studies; they are emerging as iIIJ. portant indicator species in ecolo gy; and improvements in biochemical methodology have meant they are at last amenable - despite their small size - to molecular biological study.\"\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Hardcover","offer_id":47592071725207,"sku":"9789061935421","price":22626.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9789061935421.webp?v=1774976018","url":"https:\/\/atlanticbooks.com\/products\/advances-in-the-biology-of-turbellarians-and-related-platyhelminthes-proceedings-of-the-fourth-international-symposium-on-the-turbellaria-held-at-fre-9789061935421","provider":"Atlantic Books","version":"1.0","type":"link"}
