Evolution Test Review 22-23

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

What is it called when an organism is best adapted to its environment, it will survive and reproduce more successfully than other organisms less adapted?

• cloning
• evolution of all species
• natural selection
• selective breeding

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

When unrelated species evolve similar characteristics because they live in similar

environments

• Divergent Evolution

• Speciation

• Convergent Evolution

• Punctuated equilibrium

A number of different species arise from one common ancestor

- New environments caused differences to evolve in populations

• Convergent Evolution

• Divergent Evolution

• Coevolution

• Gradualism

Occurs when two populations of organisms form a specialized relationship and thus change in response to each other

• Convergent Evolution

• Punctuated equilibrium

• Coevolution

• Speciation

Structures with the same structure have different functions; suggests that organisms share a common ancestry

• vestigial structures

• homologous structures

• adaptive radiation

• fossil

This mechanism of evolution occurs when populations migrate.

• Extinction
• Gene flow
• Genetic drift
• Natural Selection

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

Which of the following are examples of geographic isolation?

• When a storm blows a population of finches to a new island so they can no longer mate with the finches on the mainland

• A mountain range prevents two types of goat from mating, causing the gene pool to become less varied

• Two populations of deer living near each other happen to mate during different times of the year

• A deepening canyon cuts two populations of squirrels off from each other

• Two populations of birds have developed different mating calls
