D)   class, order, family, genus, species, kingdom, phylum, domainE) None of the above
F) B) and D)

Question 4

When ectoparasites first arrive and adapt to the fur or feathery habitat of a host, they often lose more complex ancestral features. So it is possible to gain a trait in evolution and subsequently lose it. However, it is considered vastly improbable that this same trait will again re-evolve. Therefore, in trying to trace evolutionary lineages, can we always expect the most primitive forms to be the simplest and the most advanced to be the most complex? Why or why not?

F) A) and C)

Question 6

Convergent evolution has occurred when distantly related species have a structure that looks the same only because of adaptation to the same type of environment.

 B)False

Question 7

Phylogenetic trees with proportional branch lengths

Accepted Answer

A)   indicate relatedness among organisms.
B)   indicate the relative number of nucleotide pair differences between groups.

E)   indicate relatedness evolutionary time.F) None of the above
G) C) and D)

Question 8

B)   paraphyletic.
C)   polyphyletic.
D)   monophyletic and paraphyletic are correct.E) None of the above

Question 9

If there are so many million insects and so few scientists to describe them, perhaps we could just assign the insects numbers and descriptions, rather than names. Describe why this would not accomplish the same "job" as giving them a scientific name, and provide two potential items of knowledge that would be missing with just a number and description. Simply, what does naming an organism also accomplish?

D)   All of the choices are correct.E) C) and D)
F) None of the above

Question 14

The principle of parsimony states that a cladogram produces the best hypothesis about relationships of organisms when the maximum number of assumptions are considered.

Accepted Answer

A) True 
 B)False
