1/25- 8th Grade Evolution

Multiple Choice

What piece of information does the fossil record NOT tell us?

• It tells us about species that once lived but are now extinct

• It tells us about species that have existed for a long period of time

• It tells us about the emergence of species that have been on Earth for a short time

• It tells us about species that are likely to emerge in the future

Multiple Choice

What can we learn about from fossils?

• What an organism looked like

• How the organism moved around the environment

• What the organism ate

• All of the above

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 complex

• They suggest there are similarities between ancient organisms and present organisms, suggesting that all living things are somehow related

• All of the above

Multiple Choice

What is evolution?

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

• The predation of one species on another species

• The change of traits in a species over time

• The conversion of a carnivore (meat eater) into a herbivore (plant eater)

Multiple Choice

What is a common ancestor?

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

• An organism from which all organisms on Earth descended from

• An organism which all organisms on Earth strive to become

• An organism that lives on a different planet as well as Earth

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 are less fit

• Organisms that reproduce very quickly

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 is detrimental to the survival of an organism

• A characteristic that makes an organism “less fit”

Multiple Choice

Survival of the fittest is:

• Organisms that exercise and diet will best survive

• Organisms with advantageous ("better") traits are more likely to survive.

• Organisms that can run the fastest will survive

• Organisms unable to complete for resources will survive

Multiple Choice

Survival of the fittest is:

• Organisms that exercise and diet will best survive

• Organisms with advantageous ("better") traits are more likely to survive.

• Organisms that can run the fastest will survive

• Organisms unable to complete for resources will survive

Multiple Choice

What is the strongest piece of evidence that supports evolution?

• The fossil record

• Embryology similarities

• Genetic similarities

• Anatomical similarities

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
