Evolution

Multiple Choice

What is evolution?

• The loss of a species (A species dies out)

• The change of traits in species overtime

• A species preys on another species

• The change of a carnivore into an herbivore

Multiple Choice

According to evolution what happens to the frequency of traits in a population of species overtime?

• The frequency of traits randomly increases

• The frequency of traits never changes

• The frequency of advantageous traits increases overtime

• The frequency of traits decrease overtime

Multiple Choice

Which statement best describes the rate of evolution?

• It is always a slow process

• It usually is a slow process but it can occur quickly as well

• It is usually a fast process but it can occurs slowly as well

• It is always a fast process

Multiple Choice

What is a common ancestor?

• A selective pressure that led to the formation of all the species on Earth

• An organism from which all the organisms on Earth descended from

• An organism which all the organisms on Earth strive to become

• An organism that lives on a different planet as well

Multiple Choice

Which of the following is NOT a postulate of Darwin's theory?

• There is little or no variation among the individuals in a species

• Individuals compete with each-other for resources

• Competition can lead to death of individuals

• Individuals who survive are more likely to reproduce and pass traits to offspring

Multiple Choice

What is an adaptation?

• A characteristic that an organism acquires during its life

• A favorable trait, which helps an organism survive

• An unfavorable trait, which hurts the chances of survival

• A trait that makes an organism "less fit"

Multiple Choice

Which organisms are more likely to survive, reproduce and pass their traits to offspring?

• Organisms that are well-adapted to the environment

• Organisms that are not well-adapted to the environment

• Organisms that reproduce very quickly

• Organisms that are less fit

Multiple Choice

Which of the following is a resource that organisms compete for?

• Water

• Space

• Mates

• All of the above

Multiple Choice

Why do organism compete with each other for resources?

• There is an unlimited supply of resources

• There is a limited supply of resources

• Organisms produce more offspring than can survive

• Both B and C

Open Ended

Why do think competition for resources is important?

Open Ended

For what type of resource is the male bird in the video competing?

Describe what the male bird is doing to get the attention of the female bird.

Describe one way human males compete for the same type of resource for which the bird is competing and one way human females compete for the same resource.

Multiple Choice

Fossils are an important piece of evidence for evolution because:

• They show that organisms have changed over time on Earth

• They demonstrate that organisms have become more and more complex

• They suggest there are similarities between ancient and present organisms

• All of the above

Multiple Choice

Which structures do NOT imply evolutionary relationships?

• Homologous structures

• Analogous structures

• Vestigial structures

• All of the structures above imply evolutionary relationships

Multiple Choice

Which structure implies "loss of function" or evolutionary divergence from a species with a past function (that is no longer needed)?

• Homologous structures

• Analogous structures

• Vestigial structures

• All of the above
