The species of finches that Charles Darwin found on the Galapagos Islands displayed different structural adaptations. One of the adaptations that Darwin noticed was the
Similarities of the birds’ embryos
Birds’ different shaped beaks
Length of the birds’ necks
Number of eggs in each bird’s nest
Which of the following is NOT an evidence for evolution proposed by Charles Darwin
Fossil record
Vestigial structures
Analogous structures
Acquired characteristics
Competition among organisms can be seen in obtaining basic necessities. Darwin described this as
Descent with modification
Struggle for existence
Survival of the fittest
Fossil record
When lions prey on a herd of antelopes, some antelopes are killed and some escape. Which part of Charles Darwin’s concept of natural selection might be used to describe this situation?
Acquired characteristics
Reproductive isolation
Survival of the fittest
Descent with modification
The idea that organisms have DESCENDED from a common ancestor with modifications over time is known as
Survival of the fittest
Natural selection
Descent with modification
Struggle for existence
Charles Darwin called the ability of an organism to survive and reproduce in its specific environment
Diversity
Fitness
Adaptation
Variation
The similarity among the blood proteins (amino acid sequences) of all mammals may be taken as evidence for evolutionary relationships based upon
comparative anatomy
comparative geographic distribution
comparative embryology
comparative biochemistry
According to Charles Darwin’s theory of natural selection, the individuals that tend to survive are those that have
Characteristics their parents acquired by use and disuse
Characteristics that plant and animal breeders value
The greatest number of offspring
Variations best suited to the environment
Charles Darwin’s theory of evolution suggests that
Species change over time
Extinct species are not related to living species
Different species can interbreed
Animals that look alike are the most closely related
The table shows the amino acid present at ten positions in the myoglobin protein in five different organisms. Based on this evidence, a researcher could conclude that
The zebra and Gorilla are closely related.
The closest relatives are the human and chimpanzee
The closest relative is Horse and Zebra
No amino acids at any position of the myoglobin protein remained unchanged across all animals.
When an seagulls's wing and a finches's wing are compared, similar bone structures are discovered. They are __________.
Analogous
Homologous
Vestigial
Variability
When DNA is copied, sometimes errors can occur. These errors can be good and bad. These errors are called________.
Recombination
Polygenic trait
Single-gene trait
Mutation
If a mutation introduces a new coloration in a moth population, which factor might determine whether the frequency of the new allele will increase?
How many other alleles are present
Whether the mutation makes some moths more fit for their environment than other moths
How many phenotypes the population has
Whether the mutation was caused by nature of by human intervention
A whale has a pelvis and a femur bone. Name and define what structures these bones represent within the whale.
Homologous Structures: Structures that are built similarly in different species, but used differently.
Analogous Structures: Structures that are build differently in different species, but used for the same function.
Vestigial Structures: Structures that aren't used, but remain in organisms that are built from DNA instructions passed on by ancestors.
Which of the following is NOT one Charles Darwin’s three hypotheses in regards to the occurrence of evolution.
Survival of the fittest: Tbe organisms with the best adaptations survive, reproduce, and pass on those adaptions.
Inheritance of Acquired Traits: Traits an organisms acquires during its lifetime are passed on to offspring.
Descent with Modification: Organisms have changed over time from their ancestors.
Struggle for Existence: Members of the same species compete for food, water, resources....
When a shark's fin and a penguin's fin is compared, different bone structures are discovered but they perform the same function.
Homologous Structures
Analogous Structures
Vestigial Structures
Variation
Using Carbon-14 dating (radioactive dating) to determine the age of a fossil is a type of
Relative Dating
Absolute Dating
Biochemical
Comparative Embryology
Law that says traits are inherited independently of each other due to allele pairs separate independently during gamete formation
Law of Independent Assortment
Law of dominance
Codominance
Incomplete Dominance
There are similarities between embryos of different species as they develop. This is evidence to support evolution. This is called _____________.
Comparative Biochemical
Comparative Embryology
Homologous Structures
The butterfly wing and bird wing have the same function, but they are structurally different. These structures are known as
Analogous Structures
Homologous Structures
Vestigial Structures
What was the book that Darwin published?
Orgin of the Species
Natural Selection
Artificial Selection

Who is known as the father of evolution?
Charles Darwin
Carolus Linnaeus
Mr. Hayden
Tupac
In genetic drift, allele frequencies change because of
Mutations
Chance
Natural selection
Genetic equilibrium
When closely related species have different traits based on the environment they live in this pattern of evolution is seen.
Divergent evolution
Coevolution
Convergent evolution
What does this graph represent?
Directional: One extreme variation of the phenotype has now become the most common phenotype
Stabilizing: The most common variation of the phenotype has become even more common.
Disruptive: Both extreme variations of the phenotype have become the most common phenotype.
This graph represents...
