Which part of an animal's body will leave the best fossils?
cartilage (ears)
teeth
skin
all are correct
When rock layers are deposited they typically radiate outward and become thinner. This is called the principle of
Lateral Continuity
Cross cutting
Faunal Succession
Superposition
When organisms are bred for specific traits such as a yellow snake with black patches this is often the result of
Natural Selection
Draft Selection
Detection Selection
Artificial Selection
Evolution can be best described as
Change over time
Mutations over time
Mutations over generations
Generations over time
What is the best way to measure the fitness of a trait?
Survivability
Muscles
Heart rate
Presence in future generations
According to Darwin, an organism with traits that are not favorable will most likely
Reach reproductive age
Not pass on traits
Survive to old age
Increase biodiversity in an ecosystem
Which fossil is the index fossil?
A
B
C
D
Evolution can occur at different rates, however, for evolution to occur, there must be
variation within a species
extinction of the species
asexual reproduction
no change in the genes of an organism
Which is not a part of Darwin's Theory?
Variation exists in species
More offspring are born than can survive
All dogs are well suited to the natural environment
There is competition for limited natural resources.
Which of the 4 categories of evidence for evolution does this image belong under?
Anatomical
Biochemical
Fossil
Embryological
Comparing DNA sequences of different organisms is an example of what type of evidence for evolution?
Anatomical
Biochemical
Embryological
Fossil
Natural Selection means
Change over time
Learned traits are passed from parent to offspring
Organisms best fit for their environment survive and pass on their traits
The strongest animals survive
The image below showing a chameleon matching the color of its surroundings is an example of
Genotype
Phenotype
Camouflage
Mimicry
Limiting factors such as food, shelter, water and predators that can change the survival of an organism are called
Adaptations
Mutations
Selective Pressures
Independent Factors
Darwin's finches developing different beak sizes due to the different food sources available on each island is an example of
Mutation
Directional Selection
Adaptive Radiation
Natural Selection
Inherited characteristic that increases an organism's chance of survival
Adaptation
Evolution
Biogeography
Extinction
Change in a DNA sequence that affects genetic information
Mutation
Fossil
genetic equilibrium
Hardy-Weinburg Principle
Body structures that have the same structure (parts), but a different function (use) are called
Analogous Structures
Homologous Structures
Vestigial Structures
Fossils
Natural Selection means
Change over time
Learned traits are passed from parent to offspring
Organisms best fit for their environment survive and pass on their traits
The strongest animals survive
Many animals who live where it snows have fur. Explain how white fur makes surviving in the snowy environment easier.
Orange fur make them easier to spot.
White fur allows them to better blend in with their habitat.
The color of fur doesn't effect an animals chance of survival.
White fur is cooler then other fur colors.
All of the genes in a population make up this:
Gene selection
Gene pool
Gene variation
Gene differentiation
Which example best illustrates the process of natural selection?
Giraffe necks varied in length, and all offspring had an equal chance of survival
Giraffe necks varied in length and the shorter-necked giraffes were at a disadvantage
Giraffes with short necks migrated to locations best suited for their neck lengths
Giraffes stretched their necks to reach for food, and resulting offspring had longer necks
