- 1. Multiple ChoiceA flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?behavioral isolationtemporal isolationgametic isolationgeographic isolation
- 2. Multiple ChoiceSome female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are beginning to only mate with the type of males with the tail they prefer. What type of reproductive barrier is this?behavioral isolationhybrid sterilitytemporal isolationmechanical isolation
- 3. Multiple ChoiceThe flowers of pink tulips open in the morning, while the flowers of lavender tulips open in the early afternoon. The bees that pollinate these tulips cannot carry pollen back & forth between the two types of tulips because of their flowers being closed at different times of day. What type of reproductive barrier is this?behavioral isolationhybrid sterilitytemporal isolationmechanical isolation
- 4. Multiple ChoiceThe term for the formation of new and distinct species over the course of evolution is...speciationbiological species conceptreproductive barriernatural selection
- 5. Multiple ChoiceWhat is a species?A group of organisms that can mate with each other and produce fertile offspring.A group of organisms that can mate and produce offspring even if those offspring are infertile.A group of organisms that genetically are very different from each other.Indivual organisms that live in the same environment.
- 6. Multiple Choice
A new river forms and splits two populations, causing ______________ speciation
Sympatric
Allopatric
Extreme
Convergent
- 7. Multiple Choice
Orcas occur in the same habitat but some are avoiding each other and do not interbreed. They have different diets, vocal behavior, and social structures. What type of speciation is this?
Allopatric
Sympatric
Complex
Covergent
- 8. Multiple Choice
The emergence of new rivers or streams is a type of ____________ isolation.
Temporal
Mechanical
Behavioral
Geographic
- 9. Multiple ChoiceWhich of the following is NOT part of the Biological Species Concept?Must meet in nature & have gene flowMust be able to reproduce & share a gene poolOffspring must be sterileOffspring must be fertile
- 10. Multiple ChoiceThe pollen (sperm) of a flowering plant cannot fertilize the egg cell of a nearby flowering plant of its kind. What type of reproductive barrier is this?behavioral isolationtemporal isolationgametic isolationgeographic isolation
- 11. Multiple ChoiceWhat evidence does speciation provide for the theory of evolution by natural selection?Speciation can show us that new species don't choose to adapt, but have changed due to diverging from an original species due to reproductive barriers.Speciation can show us that new biological species can come from divergence (separating) due to reproductive barriers.Speciation can show us that environmental changes & genetic variation play a role in the process of a new species diverging from an original species due to reproductive barriers.All of the above fit!

Multiple ChoiceWhich is an example of temporal isolation?flowers that bloom in different monthsbirds that have different mating callsfruit flies that mate in different locationssquirrels that have different fur colors
- 14. Multiple ChoiceGentoo penguins will present a mate with a pebble that they find to attract a mate. Emperor penguins have a specific call and movement that they make to attract a mate. Which type of isolation do these penguins demonstrate?temporal isolationbehavioral isolationgeographical isolationanatomical isolation
- 15. Multiple ChoiceAccording to the diagram, who is most closely related to primates?AmphibiansRodents & RabbitsCrocodilesSharks
- 16. Multiple ChoiceWhen has speciation occurred?When populations no longer look the sameWhen populations no longer have the same frequency of allelesWhen populations are living in different environmentsWhen populations can no longer interbreed
- 17. Multiple ChoiceThe disappearance of a species refers toEvolutionExtinctionMigrationMutation
- 18. Multiple ChoiceWhat type of genetic drift occurs when the population size is greatly decreased due to a random event?Founder's EffectBottleneck EffectIntrasexual SelectionIntersexual Selection

Allopatric speciation
Complex speciation
Divergent speciation
- 20. Multiple ChoiceWhich statement is true of Natural Selection?It is the same process as artificial selectionIt is the mechanism of evolutionAnimal and plant breeders select desired traits to produce changes in a speciesIt is a much shorter process than artificial selection
