Question:
What type of trait is not useful to construct a phylogenetic tree?
Answer:
S Analogous Trait
Question:
Besides mutation, what process increases the variation found in genomes?
Answer:
S Crossover
Question:
In the forests in eastern Arizona there are two species of catfish found in the streams. The species
live in the same habitat, however they rarely interbreed, because the offspring are sterile. This is
an example of
Answer:
S Post-zygotic Barrier
Question:
What condition must be present for migration to be a non-adaptive mechanism of evolution?
Answer:
S Migrants must have different allele frequencies as the new
population
Question:
A research scientist is studying egg laying behavior in the Sonoran Desert Tortoise. The number
of eggs laid by a tortoise (clutch size) appears to have less variability that expected by random
chance. The scientist hypothesizes that a small clutch limits the reproductive potential of the
female, and too large a clutch results in too little for each egg. If correct this would be an
example of
Answer:
S Stabilizing Selection
,Question:
What is the biological species concept based on?
Answer:
S if an organism
can reproduce with other organisms
Question:
Which of the following trends in the fossil record supports an evolutionary hypothesis as
described by a phylogenetic tree?
Answer:
S The appearance of novel traits
(ex feathers) in the fossil record is in agreement with the predictions of phylogenetic trees.
Question:
How has culture helped humans survive?
Answer:
S survive in extreme
environments, use more advanced and complex tools, more efficient hunting techniques

includes a common ancestor but not all of it descendants.
Question:
What is a homologous trait?
Answer:
S A trait found in more than one
, species that was inherited from a common ancestor
Question:
How does carbon enter the atmosphere in the biological carbon cycle?
Answer:
S cellular respiration
Question:
How is the age of a fossil determined?
Answer:
S measuring the amount of
radioactive isotopes left in the fossil
Question:
In the desert of east Yuma, there are two species of blister beetle. The two species do not breed
with each other because one species lives on Palo Verde trees and the other lives on Ocotillo
plants. This is an example of
Answer:
S habitat isolation
Question:
A research geneticist is examining the amino acid sequence for the chlorophyll gene in six
different species of sunflowers. The two species whose amino acid sequences have the greatest
number of differences are
Answer:
S the most distantly related of the
groups being prepared.
Question:
What is a monophyletic group of organisms?
Answer:
S A group that
includes a common ancestor and all of its descendants
