Asked in Relationships , Biology , Animal Life What is a trait that is ancestral to all chordates ? 0 Answers/Comments. Test. STUDY. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
Some examples of chordates are humans, eagles, turtles, and jellyfish. Question. A chordate (/ ˈ k ɔːr d eɪ t /) is an animal of the phylum Chordata.During some period of their life cycle, chordates possess a notochord, a dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail: these five anatomical features define this phylum.Chordates are also bilaterally symmetric, and have a coelom, metameric segmentation, and circulatory system. STUDY. Spell. It is located between the digestive tube and the nerve cord, and provides skeletal support through the length of the body. Flashcards.

Cephalochordates develop in the open water, but as adults they lie partially or entirely buried in sand and gravel. Tunicates and Cephalochordates. Write. A trait present in an ancestral organism is modified by natural selection over time in descendants of that ancestor. A trait that is ancestral to all chordates is the nothocord.
