eukaryote, multicellular, heterotroph, sexual or asexual reproduction, and most move at some point in their life cycle
-eukaryote, multicellular, autotroph, sexual or asexual reproduction, and use photosynthesis
A group of related families is called a(n)______________.
species
order
genus
phylum
The geographic isolation of two populations of a species tends to increase differences between their gene pools (genes within their population) because it
prevents interbreeding between populations.
causes temporal isolation of the two populations.
increases differences in courtship behavior.
allows interbreeding between populations.
The founder of modern evolution theory is considered to be _____.
Charles Darwin
Alexander Oparin
Carlos Linneaus
Lynn Margulis
Structures that have similar evolutionary origin and structure but are adapted for different purposes, such as a bat wind and a human arm, are called ______.
embryological structures
analogous structures
homologous structures
homozygous structures
A paleontologist is comparing the fossilized remains of two primates. Both animals had a prehensile tail. What can be concluded from this evidence?
They were not related.
The lived on the ground.
hey evolved from a common ancestor.
They had bipedal locomotion.
Based on their names, you know that the babboons Papiio annubis and Papiio cynocephalus do NOT belong to the same
class.
family.
genus.
species.
The flying squirrel of North America closely resembles the flying phalanger of Australia. They are similar in size and have long, bushy tails and skin fold that allow them to glide through the air. The squirrel is a placental mammal, while the phalanger is a marsupial, but they live in similar environments. The close resemblances, even though genetically and geographically separated by great distances, can best be explained by _____.
convergent evolution
divergent evolution
spontaneous generation
vestigial structures
In each generation, the wings of experimental fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on
inheritance of natural variations.
inheritance of acquired characteristics.
natural selection.
survival of the fittest.
Which is the best evidence of an evolutionary relationship between two organisms?
similarity in behavior
similarity in DNA
similarity in niche
similarity in habitat
When lions prey on a herd of antelopes, some antelopes are killed and some escape. Which part of Darwin's concept of natural selection might be used to describe this situation?
acquired characteristics
reproductive isolation
survival of the fittest
descent with modifications
Walruses live in the Arctic and have a thick fat layer. The ancestors of modern-day walruses might not have had such a thick layer. Over time, the walruses have probably changed. According to the theory of evolution by natural selection, what is the most likely reason that this change has probably occurred?
The walruses wanted to adapt to teh cold climate, so they learned to develop thicker fat layers.
The walruses that had thicker fat layers were more apt to survive and live to reproduce.
The walruses inherited a thicker fat layer from their parents.
Each successive generation, more walruses have thicker fat layers.
Variation within a species was important to the development of Darwin's theory of evolution. Which statement does individual variation help explain?
Resources become limited over long periods of time.
Populations often increase rapidly and without warning.
Competition is fierce among members of different species.
Some organisms survive and reproduce better than others.
What is the difference between the full classification of organisms and their scientific names?
The full classification of organisms and their scientific names vary in different countries.
The scientific names of organisms include the order and family of the organisms, but the full classification includes only the species name.
The full classification of organisms will include more categories of organisms than their scientific names.
The scientific names of organisms include a single nomenclature, but the full classification includes various nomenclatures.
The use of pesticides on crops has been a common farming practice for decades. What has been the greatest effect of natural selection through the use of pesticides on certain insect populations?
Natural selection has been altered beause the insects and their predators are killed.
The rate of selection is increased because the pesticides do not kills the insects that are naturally resistant to it.
The rate of selection is increased because the pesticides do not kills the insects that are naturally resistant to it.
The pesticides have altered natural selection by causing the insect DNA to spontaneously mutate.
This diagram represents the bone structures of the front limbs of four different animals. What do the similarities of the structures suggest about these organisms?
They grow at the same rate.
They live in the same environment.
They live for the same length of time.
They evolved from a common ancestor.
According to fossil records, the horses that lived 50 million years ago were much smaller, weaker, and slower than modern horses. Which process is most likely responsible for the changes that have led to the increased size, strength, and speed in horses?
commensalism
inbreeding
migration
natural selection
A type of learning in which an animal, at a critical time in its life, forms a social attachment to another object is called _____.

Parasitism
Predation
DTR: Barnacles live on a whale and get nutrients that float nearby. The whale does not receive a benefit and doesn't get hurt from this relationship
Mutualism
Commensalism
Parasitism
Predation
