Question 6

____ is the study of a species' evolutionary history.
A) Natural selection
B) Taxonomy
C) Microevolution
D) Phylogeny
E) Convergent evolution

Accepted Answer

Phylogeny is the study of the evolutionary history and relationships among individuals or groups of organisms. These relationships are discovered through molecular sequencing data and morphological data matrices.

Question 7

​Phylogeny is most analogous to a ____.
A) ​family genealogy
B) ​burst of new computer technology
C) ​telescopic view of the early universe
D) ​traffic light
E) ​roller coaster

Accepted Answer

Phylogeny, which refers to the evolutionary history and relationships among individuals or groups of organisms, is most analogous to a family genealogy. Both involve tracing lineages and understanding how different entities are related to each other over time.

​A group of organisms sharing a derived trait is known as a ____.
A) ​clade
B) ​taxon
C) ​tribe
D) ​community

Accepted Answer

A clade is a group of organisms that includes an ancestor and all descendants of that ancestor, identified by shared derived traits.

Question 14

​In the work that they do, scientists who study phylogeny are most like a ____.
A) ​police detective
B) ​medical doctor
C) ​carpenter
D) ​college professor
E) ​real estate agent

Accepted Answer

Scientists who study phylogeny, which involves understanding the evolutionary relationships among species, are similar to police detectives in that they both gather evidence to solve mysteries. In the case of phylogeneticists, the mystery is the evolutionary history and relationships among organisms, while detectives solve crimes. Both require careful analysis of evidence to construct a narrative or solve a puzzle.

Question 15

​The use of phylogeny to determine evolutionary relationships has practical applications in ____.
A) ​preserving extinct species
B) ​tracking infectious disease
C) ​tracking migration patterns
D) ​raising livestock
E) ​managing invasive species

Accepted Answer

Tracking infectious disease is a practical application of phylogeny because it allows scientists to determine the evolutionary relationships between different strains of a pathogen and track how they spread.

Question 16

A female horse can mate with a male donkey, but they will produce a mule that is sterile. This is an example of what type of isolation mechanism?
A) allopatric
B) physical
C) behavioral
D) reproductive
E) geological

Accepted Answer

Reproductive isolation mechanisms prevent species from breeding with each other. The sterility of the offspring (mule) from a horse and donkey mating is a postzygotic barrier, a type of reproductive isolation.

Question 17

The branch points on a cladogram represent ____.
A) the species' extinction
B) derived characters
C) related clades
D) a common ancestor of two lineages
E) mass extinctions

Accepted Answer

Branch points on a cladogram represent a common ancestor of two lineages, indicating where they diverge from a shared lineage.

-When a small group of individuals found a new population, allele frequencies in the descendants differ from those in the original population.
A)genetic drift
B)inbreeding
C)bottleneck
D)founder effect
E)fixed
F)gene flow

Question 20

​Alligators more closely resemble lizards than birds; however, alligators and birds have four-chambered hearts, which lizards do not have. In this example, the four-chambered heart is a ____, which indicates that alligators are ____ related to birds than to lizards.
A) ​derived character; more closely
B) ​key innovation; more closely
C) ​derived character; more distantly
D) ​key innovation; not
E) ​homologous structure; more distantly

Accepted Answer

The four-chambered heart is a derived character, meaning it is a trait that appeared in the most recent common ancestor of a particular lineage and was passed on to its descendants. This shared derived character between alligators and birds indicates that they are more closely related to each other than either is to lizards, which do not have this trait.
