Evolution
Evolution is
a. Change in an individual throughout time
b. Change in a population throughout time
c. The genetic variations within a population
d. Traits given to offspring
b. Change in a population throughout time
Which one is not a mechanism of evolution?
a. Gene flow
b. Artificial selection
c. Natural selection
4. Genetic variation
d. Genetic variation
What is natural selection?
a. Process where individuals with traits most suitable for the environment have lower survivorship and reproductive success
b. Process where individuals with traits most suitable for the environment have higher survivorship and reproductive success
c. Process where organisms just evolve randomly
d. Process where individuals with traits least suitable for the environment have higher survivorship and reproductive success
b. Process where individuals with traits most suitable for the environment have higher survivorship and reproductive success
A Species is
a. Organisms that have different habitats and traits
b. Organisms with similar reproductive patterns and habitats
c. Organisms that have different reproductive patterns and traits
d. Organisms with similar reproductive patterns and traits
d. Organisms with similar reproductive patterns and traits
What is the name of the process where organisms produce new species types when changes in the environment have new resources become available and generate new niches within the environment?
Adaptive radiation
Features on different species that have the same structure and have origins from the same common ancestor
a. Reciprocal structures
b. Homologous structures
c. Exemplary structures
d. Analogous structures
b. Homologous structures
Evolution mechanism where a random occurrence results in the population having less gene types
a. Gene flow
b. Natural selection
c. Founder effect
d. Bottleneck effect
d. Bottleneck effect
Which one is not one of the four requirements for natural selection?
a. Reproduction
b. Selective pressure
c. Genetic variation
d. Geographic isolation
d. Geographic isolation
Which of the following is required for speciation to happen?
a. Behavioral isolation
b. Reproductive isolation
c. Geographic isolation
d. Habitat isolation
b. Reproductive isolation
Evolution where organisms evolve into having reciprocal structures that allow the species to interact easier with one another
a. Divergent evolution
b. Emergent evolution
c. Coevolution
d. Convergent evolution
c. Coevolution
What is the mechanism where one population moves into another, increasing the genetic variation within the new population?
Gene flow
Natural selection can result in organisms within a population becoming different species as a result of different groups in the population having different traits and reproductive behaviors. What is the name of the process where a population becomes different species?
Speciation
Speciation type where geographic barrier separates two groups of organisms, resulting is speciation
Allopatric speciation
Traits that allow organisms to better live in their environments
Adaptations
If humans selected purple plants from a garden and then breed those plants to make a garden of purple plants, are they decreasing or increasing genetic variation?
Decreasing
Harsher temperatures in mountains that cause organisms with heavier fur to survive is an example of which natural selection condition?
Selective pressure
Post reproductive barrier that prevents adult hybrid organisms from having offspring
Sterility or hybrid sterility
Mutations
A group of rabbits within a population of rabbits move to a new region where they are the first rabbits there. The new rabbit population does not have as many gene types in the population. What evolution mechanism are they experiencing?
Founder effect
The condition of natural selection where organisms give their favorable traits to their offspring
Heredity or inheritance
Isolation mechanism where where organisms cannot reproduce with one another because they have different breeding seasons
Temporal isolation
