Basic Concepts
Natural Selection
Speciation & Isolation
Evidence for Evolution
Evolution Patterns
100
A change in species over time
What is a evolution?
100
The concept that organisms that are best suited to their environment will survive and reproduce
What is natural selection?
100
The formation of new species is called____________.
What is speciation?
100
Preserved remains of ancient organisms
What are fossils?
100
True or False: Unrelated species evolving similar traits is called divergent evolution.
What is false?
200
When an entire species dies out completely
What is extinction?
200
Natural selection happens because individuals in a population are not all the same. This is called v _ _ _ _ _ _ _ _.
What is variation?
200
Organisms moving from a population of one species to a separate population of the same species, changing the allele frequency or introducing new traits
What is gene flow
200
What type of evidence is depicted below?
What is embryological evidence?
200
Species that share a common ancestor but evolve differently is called D_ _ _ _ _ _ _ _ evolution.
What is divergent evolution?
300
Producing more offspring than what can survive
What is overproduction?
300
What does the "selecting" in natural selection?
A. Miss Mack
B. The environment
C. Genetics
What is B. The environment?
300
Two types of toads mate during seasons. What type of isolation is this?
A. Geographical
B. Behavioral
C. Temporal
What is temporal isolation?
300
The whale's pelvic bones are an example of?
What is vestigial structure?
300
The evolutionary diversification of a single ancestral line where organisms display different adaptations in response to different selection pressures
What is divergent evolution (adaptive radiation)?
400
An organism's ability to survive and reproduce.
What is fitness?
400
Natural selection leads to organisms becoming better suited for their environment. This is called_________.
What is adaptation?
400
A decline in genetic variation when a small group becomes separated from a larger population
What is the founder effect?
400
Has similar bone structures and a common ancestor
What are homologous structures?
400
When adaptations of one species cause similar adaptations in another species, often found in species with symbiotic relationships, or parasites
What is coevolution?
500
When humans breed organisms for specific features (example: certain dog breeds like pugs)
What is artificial selection?
500
True or False: A population with little genetic diversity is more likely to adapt to environmental changes.
What is false?
500
A sharp decline in a population's genetic variation due to outside forces or random events
What is the bottleneck effect?
500
Has similar functions but different structures and do not share a common ancestor 
What are analogous structures?
500
The process where organisms that are not closely related develop similar traits as adaptations to similar environments
What is convergent evolution?
