Who introduced the theory of natural selection?
Rachel Carson
Alexander Fleming
Charles Darwin
Francesco Redi
What determines an organisms fitness?
Their ability to hunt
Their ability to survive
Their size
Their ability to reproduce
What is a mutation?
Any change in the sequence of DNA in a cell and can be beneficial, harmful, or have no impact
A negative change in the sequence of DNA
Any DNA that is passed on to offspring
Traits that organisms have adapted to overcome their environmental struggles
What is recombination?
The measure of ones ability to reproduce
The "shuffling" process by which genetic material from different individuals combines during reproduction
Natural selection
A specific type of gene mutation that negatively harms its host
What is adaptation?
Something that hinders an organism
Something that has no affect on the organism
It is a change in an organism that allows that organism to better survive in the environment.
A trait that is not passed down to an organism's offspring
What is genetic drift?
Mass death
Survival of the fittest
the movement of alleles into and out of populations.
Specific traits, controlled by alleles on a chromosome, can become more or less common in a population by complete chance.
What is the main difference between natural selection and genetic drift
Genetic drift is determined by chance. Natural selection is determined by survival of the fittest
Genetic drift occurs inside the population whereas natural selection only occurs outside
Natural selection is determined by chance, Genetic drift is determined by survival of the fittest.
There is no differences between natural selection and genetic drift
What is gene flow?
Survival of the fittest
Only refers to organisms going or flowing out of the population instead of coming in
The movement of alleles in and out of a population which can either increase or decrease the genetic population.
the idea that specific traits, controlled by alleles on a chromosome, can become more or less common in a population completely by chance.
What are the factors of evolution (SELECT ALL THAT APPLY)
Variation
Traits can be passed onto offspring
Over-reproduction
The individuals that have living offspring possess the traits that help them survive and reproduce; therefore, they are the individuals that are naturally selected by the environment to thrive.
What is homology?
the relatedness or similarities in traits between organisms that suggest common ancestry.
The differences in traits between organisms that reject common ancestry
The ability to reproduce
The breaking up of the huge land mass, Pangaea
Which of these homologies suggest common ancestry? (PICK ONE ANSWER)
embryological homologies
anatomical homologies
molecular (DNA and amino acid sequence) homologies.
all of the above
What are vestigal structures?
Structures that give an advantage in the organism
It is a type of molecular homology
structures that no longer have a use in the organism.
Structures that are starting to develop in the organism
What two conditions must be true for a group of animals to be considered the same species? (SELECT ALL THAT APPLY)
able to reproduce
have similar physical characteristics
able to produce fertile offspring
all of the above
What is variation among DIFFERENT species?
intraspecific variation
adapatation
recombination
interspecific variation
What is variation among the SAME species?
genetic mutation
intraspecific variation
homologies
interspecfic variation
In which type of process are humans the selective agent?
Homology selection
Artificial selection
Natural selection
Humanoid selection
What is the founder effect?
genetic drift that occurs after the start of new population.
Mass reproduction
The death of the founders of a new population
A series of harmful mutation at the start of a new popluation
FILL IN THE BLANK: Populations become isolated when there is no -----
Gene flow
Genetic mutations
Genetic drift
Homologies
What is speciation?
the creation of a totally new species that DID NOT develop from any previous species
Biodiversity
Mutations
the rise of two or more species from one existing species because of behavioral or geographical barriers.
What is the difference between intrasexual selection and intersexual selection?
Intrasexual selection: competition among males
Intersexual selection: males display certain traits to females
Intersexual selection: competition among males
Intrasexual selection: males display certain traits to females
Intersexual selection: competition among females
Intrasexual selection: males display certain traits to males
Intersexual selection: competition among females
Intrasexual selection: females display certain traits to males
What is biodiversity?
The measure of variation only in a specific species
The mass dying of organisms
Biodiversity is a measure of the variety of species and intricate interactions that support each other within a geographical region.
The ability to survive
