Textbook Question
Chapter 32.2, Problem 1SB
On a field trip to a lake, a college student captures a worm-shaped animal with segmented body wall muscles. While examining the specimen in the laboratory the following day, she determines that the main nerve cord runs along the ventral side of the animal. Is this animal a chordate?

Pharyngeal slits are which of the following?
Question 24 options:
a)
Openings in the pharynx. In aquatic chordates they allow for exit of water that enters the mouth.
b)
Elongations of the posterior portion of the body. Use for locomotion in fish, or balance in some terrestrial vertebrates.
c)
Flexible, rod-shaped structures that grows from mesoderm. Gives support to an animal in embryonic development of chordates or for entire life depending on the species.
d)
Tissues that produces thyroid type hormones.
e)
Hollow tubes that develops from ectoderm. Develops into the central nervous system.
Very few fossils of Sahelanthropus have been found up until now, therefore we do not have a complete image of what its full skeletal anatomy might have looked like. What additional evidence would we need to find in order to better understand the locomotion of this species?
