Question
Chapter 26, Problem 3RQ
Summary Introduction
To determine: The three groups of amniotes based on the morphology of the skull and to explain the way in which the skulls differ.
Introduction: In the late Paleozoic era, the amniotes came into existence and diversified. Amniotes diversified in the early Permian period and this diversification provides many advantages for amniotes. The derived features of amniotes are the amniotic eggs, skeletal features, skin resistant to desiccation, and rib ventilation.
Summary Introduction
To determine: The living amniotes that emerged from these groups.

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.
The following image is from a scientific publication by paleontologist Niel Shubin, who was part of a team who discovered the earliest known tetrapod, Tiktaalik. What does

2006).
Gyptolepis
Suriptens
Eusthenopteron
Panderichitys

Nothing can be concluded about the relationship
They are analogous structures
The structures are unrelated
They are homologous structures
Amniotes are divided into three groups based on their skull mor-phologies. What are these three groups, and how do their skulls dif-fer? Which living amniotes, if any, originated from each of these three groups?
