About this document
Hemichordata: Pterobranchia & Enteropneusta by muhammadismail is a document available to read on EtoBox.
This document discusses the phylum Hemichordata and conflicting views on deuterostome phylogeny. It notes that Hemichordata includes acorn worms and sea angels, which share similarities to echinoderms and chordates. While traditionally considered close to chordates, molecular evidence strongly supports that hemichordates are more closely related to echinoderms as the sister group "Ambulacraria". This poses challenges to understanding the evolution of deuterostome characteristics.
