What is the type of natural selection where individuals for the extreme type are more likely to survive and reproduce; produces a shift in normal distribution?
Genetic Drift
Disruptive Selection
Directional Selection
Stabilizing Selection
What is the type of natural selection where individuals of the intermediate traits are lost and both extreme forms are more likely to survive and reproduce?
Genetic Drift
Disruptive Selection
Directional Selection
Stabilizing Selection
The name of the process where a species move to a different area and creates a new entirely different population.
Natural Selection
Genetic Drift
Mutation
Gene Flow
What is the type of natural selection where the intermediate trait is more likely to survive and reproduce; decrease in the extreme forms?
Genetic Drift
Disruptive Selection
Directional Selection
Stabilizing Selection
A type of genetic drift in which small groups of organisms separate from larger populations to form new colonies.
Bottleneck Effect
Founder’s Effect
Artificial Selection
Natural Selection
Charles Darwin had no intention of publishing his works because he knew it would be a logistical nightmare for his family.
True
False
The smaller the gene pool, the higher the diversity of mates and less likely for the bottleneck effect to occur when a natural disaster strikes.
True
False
An example of the Bottleneck Effect is when a natural disaster hits, drastically reducing the large population and new gene pool contains only survivors.
True
False
Microevolution is large changes over a very large time scale.
True
False
The mechanisms for evolution are mutations, gene flow and natural selection.
True
False

similar embryology
geographic distribution
fossil record
Match the type of evidence to its corresponding component of evolutionary support.
Reveals similarities in body structures and functions between organisms
Homologous Anatomical Structures
Determines time in which a species was living and reveals extinct species
Fossil Evidence
Reveals genetic sequence similarities and differences between organisms.
Molecular Evidence
Analogous Structure
Same function different structure
Homologous Structure
Same structure different function
Comparative Embryology
Comparing embryological development of different species
Biochemical Evidence
Comparing DNA and amino acid sequences of different species
Vestigial Structures
Structures in the body of an organism that no longer work.
The fossils found closer to the surface of the ground are generally -
(a)
The preserved remains of an organism, or the trace evidence of an organism’s existence in the past. (a)
Evidence for a (a) can be found in the fossil record

How does comparative anatomy provide evidence for evolution?
By disproving the theory of evolution
By proving that all organisms have identical anatomy
By focusing solely on molecular biology
By showing structural similarities and differences among species
Why are homologous structures important in studying evolution?
They are unrelated to evolutionary theory
They indicate a common ancestry
They suggest that all species have the same DNA
They show that species do not evolve
