Question
Chapter 23, Problem 13RQ
Summary Introduction
To determine: The currently favored explanation for the evolution of vertebrate jaws.
Introduction: The vertebrate jaws are found in bony fishes. They are of two types: oral jaws and pharyngeal jaws. The jaws are present at the back of the throat of a bony fish. Jaws help in biting, crushing, and moving of food from the mouth to stomach.

Students have asked these similar questions
Find the hash mark indicating the origin of jaws. Which groups of vertebratespossess jaws? Which group(s) diverged before jaws originated?
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.
Find the hash mark indicating the origin of jaws. Which group or groups of vertebrates possess jaws? Which group(s) diverged before jaws originated? Are birds more closely related to amphibians or to crocodiles? Explain how you know this.

Which one of the following statements about the characteristics of different groups of modern jawed fish is INCORRECT? a. Ray-finned fish possess a bony skeleton and an operculum covers the gills. b. Cartilaginous fish are denser than water and maintain buoyancy using fins and a large oil-filled liver. c. Lobe-finned fish such as dipnoi possess both gills and lungs. d. Ray-finned fish possess fins supported by skeletal extensions of the pectoral and pelvic areas and moved by muscles. e. Cartilaginous fish possess flexible cartilage skeletons, which is a derived character.arrow_forward

They are endothermic. This group gives birth to live young at a fetal stage. Most then nurture their young in a pouch.

Most modern day fish are in this group. They use gills to breathe and have a swim bladder to help control buoyancy. They also have a lateral line to detect vibrations in the water.
