Abstract

Hemichordates resemble chordates in important aspects of their development anatomy and physiology. Within the hemichordate phylum are two main subgroups, the enteropneusts, of a few hundred species, and the pterobranchs, of 20 or so species. Comparison of hemichordates and chordates allows deductions about the common ancestor from which they both evolved.
