Processes (Mechanisms) of Evolution

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

• Genetic Drift
• Natural Selection
• Non-random mating
• Mutation

Wolves from the Arizona mesa were transferred to the Colorado Rockies after a forest fire destroyed their habitat. They quickly became part of the local pack and had offspring.

• Mutation
• Natural Selection
• Genetic Drift
• Gene Flow

What does the image represent?

• Gene flow
• Gene drift
• Mutation
• Adaptation

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

Gene Flow tends to ___________ genetic variation (diversity)

• Increase
• Decrease
• Stabilize
• Exaggerate 

Which of the following is NOT an example of natural selection? 

• People selectively breeding hamsters.
• Insect populations developing resistance to certain pesticides.
• Bacteria becoming resistant to antibiotics.
• Male birds of certain species developing colorful feathers to attract female mates.

Evolution by chance, survival of the luckiest:

• genetic drift

• sexual selection

• fitness

• coevolution

This is one of the mechanisms of evolution; it is a continuous process in which organisms with traits that make them better-adapted to their environment are more likely to survive and reproduce than organisms without such adaptations

• Directional selection

• Microevolution

• Gene flow / genetic drift

• Natural selection

This is the process that ultimately creates new variations and changes in DNA; leads to the creation of new alleles

• Mutation

• Microevolution

• Natural selection

• Gene flow / genetic drift

Genetic drift is change in the allele frequency of a population due to...

• random chance
• natural selection
• non-random mating (sexual selection)
• artificial selection
