classification of the frog Rana sphenocephala.

8. Zoologists used to refer to animals as "simple'' and "advanced.'' Now it is more scientifically accurate to
use

forms are derived from them but lost complex characters and secondarily became more "simple".

descendants.
C. does not include the most recent common ancestor of all members of the group.
D. excludes the most recent common ancestor of all members of the group.

group) constitutes which of the following?
A. a meaningful statement of the evolutionary advancement of the birds over the reptiles
B. a meaningful statement that birds represent a different, but not necessarily more advanced adaptive
zone than reptiles
C. a trivial statement that birds evolved from something that they are not
D. an incorrect statement because ancestral groups must be extinct but reptiles are still alive

recently than either one does with another taxa.
A. outgroups
B. sister groups
C. sibling species
D. paraphyletic

specimen as seen in the ______ species concept.
A. typological
B. biological

B. named by Linnaeus who was born in 1758.
C. named by Linnaeus and the description was published in 1758.
D. named by Linnaeus and based on a specimen collected in 1758.
18. The biological species concept by Theodosius Dobzhansky and Ernst Mayr defines a species in the
textbook as a group of interbreeding natural populations reproductively isolated from other such groups
and occupying a specific niche. Such a definition cannot be used for
A. fossils.
B. asexual organisms.
C. determining species based on dead or preserved specimens.
D. organisms that cannot be raised in captivity, easily bred, or with very long generation times.
E. All of the choices pose problems for the biological species concept.
19. An entomologist discovered that two morphologically identical crickets sang completely different
mating songs and this resulted in the two populations never mating. Thus they were
A. sister groups.

called a/an ___________________________ _______________________.

not a place where life is led" is the classical description of a/an ___________ ____________________.
