what character make echinoderm are the ancesstor of chordate
Answers
Explanation:
Echinoderms have a unique water vascular system with tube feet. This allows slow but powerful movement. Chordates include vertebrates and invertebrates that have a notochord. Chordates also have a post-anal tail, dorsal hollow nerve cord, and pharyngeal slits
Answer:
Chordates are coelomate deuterostomes, and probably share a common ancestor with echinoderms. Three important characteristics unite the Phylum Chordata. At some point in their life cycle, (primitive chordate embryos) all chordates have a notochord, a dorsal hollow nerve cord, and pharyngeal gill slits.
So, the correct option is, 'embryos of some echinoderms are similar to primitive chordate embryos'.
