Example Question #5 : Evolution
Which of the following is false of the phylum chordata?
Possible Answers:
They have a notochord at some point in their development
They are protostomes
They have a coelom
They have bilateral symmetry
Correct answer:
They are protostomes
Explanation:
All chordates are deuterostomes, not protostomes. During early development, the formation of the blastopore leads to the growth of the digestive tract. In protostomes, the blastopore develops into the mouth, while in deuterostomes it becomes the anus.
All chordates have a notochord during development, which eventually gives rise to the nervous system. Chordates also have a coelom, or fluid filled cavity, somewhere within the body and they all exhibit bilateral symmetry.
