What are the two key points of Darwin's Theory of Evolution?
Species originated by Creationism and the Great flood
Species change over time and they change by natural selection
Species are determined by genotype and phenotype
Adaptation and mutation never create new species
True or False: “Mutations are caused by selective pressure in the environment.”
True
False
True or False: “The same mutation could be advantageous in some environments but deleterious in others.”
True
False
True or False: “The appearance of dark-colored volcanic rock caused the mutation for black fur to appear in the rock pocket mouse population.”
True
False
Which of the following is an example of an adaptation?
camouflage
a bee carrying pollen from one flower to another
peppered moths
hunting a population near to extinction
20 ants leave and start a new colony
Which of the following is an example of the bottleneck effect?
camouflage
a bee carrying pollen from one flower to another
peppered moths
hunting a population near to extinction
20 ants leave and start a new colony
Which of the following is an example of the founder effect?
camouflage
a bee carrying pollen from one flower to another
peppered moths
hunting a population near to extinction
20 ants leave and start a new colony
Categorize each item, you might use some answers more than once.
Some seeds blow on the wind and end up on a new island
Caused by environmental pressure
Leads to evolution
A hurricane wipes out the beach plants that have shallow roots, but the ones with deep roots survive
Some seeds have a mutation that makes them more sticky, so they are able to stay on pollinators longer
A hurricane wipes out half the beach rose plants on a beach
Completely random
Can lead to a change in allele frequency
Natural Selection
Genetic Drift
Individual organisms evolve.
True
False
In evolution, what does 'fittest' mean?
The oldest
The prettiest
The strongest
Best adapted to survive
Do the fittest organisms always live the longest in evolution?
No, fitness is about reproductive success.
Yes, they have higher life expectancy.
Yes, they adapt to their environment better.
No, the weakest always die first.
Which of these is a main reason why reproduction is an important step for evolution?
It ensures survival of the fittest individuals.
It allows for hybridization between species.
It accelerates the process of natural selection.
It enables genetic diversity and variation to occur.
The change in populations over time.
Evolution
Genetic Drift
Punctuated equilibrium
Natural selection
A priest who served as a naturalist on the H.M.S. Beagle. Formed Theory of Evolution by Natural Selection.
Thomas Malthus
Alfred Russel Wallace
Charles Darwin
Jean Babtiste Lamarck
A body structure in a present day organism that no longer serves its original purpose
Vestigial organ
The human appendix is an example
Internal organ
All of the above
Only A&B
A mechanism for change in populations where an organism with a favorable trait survives, reproduces, and pass the favorable phenotype to the next generation. Organisms without the favorable phenotype are less likley to survive and reproduce.
Directional Selection
Natural Selection
Disruptive Selection
Structural Selection
Body parts that do not have a commom evolutionary origin but are similar in function
Analogous structures
Homologous structures
vestigial structures
Evidence of Evolution.......
Fossil
Anatomical
Embryological
Biochemical
All of the above
Speciation can occur when a physical barrier divides a population.
Allopatric Speciation
Reproducive Isolation
Genetic Equilibrium
Adaptive Radiation
Structural features with a common evolutionary origin
Bird, whale, and human forearms are examples
Homologous structures
Analogous structures
A&B
What is the term for a feature that allows an organism to survive better in its enviroment?
variation
adaptation
homologous structure
vestigial structure
The hind leg bones in a whale are examples of
homologous structures
analogous structures
fossil structures
vestigial structures
What is the process in which humans breed organisms for certain traits?
natural selection
inheritance of acquired characteristics
artificial selection
descent without modification
When the DNA of an organism is altered it is referred to as...
Mutation
Genetic drift
Gene Flow
Sexual Selection
Which of the following is not an example of natural selection?
people selectivley breeding hamsters
bacteria becoming resistant to antibiotics
insect populations developing resistance to certain pesticides
male birds of certain species developing colorful feathers to attract female mates
Two organisms that are closley related would have
very similar DNA sequence
exactly the same DNA sequences
no proteins in common
completlely different DNA sequence
Why are advantageous traits more likley to be passed onto offspring?
Because they are more likley to survive and reproduce
Because they come from dominent alleles
Because they come from recessive alleles
Because the trait is an acquired phenotype
The ability of an organism to survive and reproduce in its specific enviroment
diversity
evolution
adaptation
fitness
What happens in allopatric speciation?
Adaptive radiation occurs
Mutations are spread randomly
Populations interbreed
Geographic barrier separates populations
Which of the following is an example sympatric speciation?
Darwin's finches on different islands
Hawaiian honeycreepers competing for resources
Apple maggot flies in the same orchard as their ancestors
Cheetahs separated by geography
Which of the following describes geographic isolation?
Random mating among individuals
Random changes in allele frequencies
Physical barrier prevents gene flow
Natural selection for advantageous traits
Match the term to the definition
postzygotic barriers
single-cell fertilized egg
prezygotic barriers
multicellular early stage of development (pre-birth)
zygote
prevent organisms from mating and producing a fertilized egg
embryo
prevent fertilized eggs from becoming fertile offspring that survive and reproduce
Temporal isolation
Habitat isolation
Behavioral isolation
Geographic isolation
Infertile offspring
Weak/short-lived offspring
