U7_Evolution Notes

Multiple Choice

What does Darwin's Theory of Evolution state about the development of life on Earth?

• Life on Earth developed from non-living matter spontaneously.

• Life on Earth has remained unchanged since its beginning.

• Life on Earth developed from preexisting life over time.

• Life on Earth is a result of individual creation events for each species.

Multiple Choice

According to Darwin's Theory of Evolution, how have modern life forms adapted?

• By changing their genetic makeup in a single generation.

• By moving to different environments to avoid adaptation.

• By physically adapting to their environment over many generations.

• By remaining static to preserve their original form.

Multiple Choice

What does the fossil record provide evidence of?

• The future predictions of organism development

• The past and relationships among organisms and their changes over time

• The current status of ecosystems

• The dietary habits of ancient organisms

Multiple Choice

What can studying the fossil record help us learn?

• How to create fossils

• The exact DNA sequence of ancient organisms

• Which organisms lived at certain times in Earth's history

• How to predict future evolutionary changes

Multiple Choice

What does a change in the fossil record often indicate?

• A new species has evolved

• A mistake in the dating process

• A change in Earth's environment

• The discovery of a new element

Poll

Do you think the modern day elephant and the wooly mammoth share a common ancestor?

• YES!

• NO!

Poll

What about the T-rex and chicken, do they share a common ancestor?

• YES!

• NO!

Multiple Choice

What is a common ancestor?

• A distant relative that an organism shares with another.

• A species that is found in the same habitat.

• A direct parent of an organism.

• A similar species that currently lives alongside another.

Multiple Choice

What does it mean if the common ancestor is more recent?

• The organisms are less closely related.

• The organisms live in the same environment.

• The organisms are more closely related.

• The organisms have no relation at all.

Multiple Choice

What is the study of the similarities and differences in the structures of different species called?

• Comparative embryology

• Evolutionary biology

• Comparative anatomy

• Genetic analysis (DNA)

Multiple Choice

Why do the wings of a bird and a butterfly represent analogous structures?

• Because they look similar and evolved to do the same job, but evolved independently.

• Because they have the same pattern of bones inside the wings.

• Because they were inherited from a common ancestor.

• Because they are vestigial structures that have reduced in size.

Multiple Choice

What does the vestigial pelvis in whales suggest about their evolution?

• Whales have always been aquatic animals without the need for legs.

• Whales have a vestigial pelvis as a result of convergent evolution.

• Whales have a vestigial pelvis because they evolved from a common ancestor with legs.

• Whales have a vestigial pelvis because they are starting to evolve legs.

Multiple Choice

Why do the forelimbs of humans, cats, whales, and bats have different functions?

• They have evolved to suit the specific needs and lifestyles of each species.
• They were created at different times
• They are made of different materials
• They were designed by the same architect
