Evidence of Evolution

Which of the following is the collection of life's remains found in sedimentary rock?

• natural selection

• homologous structures

• Charles Darwin

• the fossil record

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show how life forms present today are different than those from the past
• Different sedimentary rock layers provide evidence for how the environment has changed over time

Which layer is the youngest

• 1
• 2
• 3
• 4

Which is the relatively youngest fossil?

• gastropod

• trilobite

• coral

• ammonite

If two organisms have similar DNA they probably

• share a common ancestor
• share a common environment
• share a common population
• speciation

The picture shows a/an ___________

• homologous structure

• vestigial structure

• analogous structure

What is this an example of?

• Homologous structure

• Analogous structure

• Vestigial organs

• Functional adaption

Which of the following is an example of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the tailbone of a human

Which is not evidence for evolution?

• many animals have homologous structures due to common ancestry
• Many animals have vestigial structures from an ancestor
• We can observe changes in life forms by observing the fossil record
• All of these are evidence for evolution

A bat wing and a butterfly wing are both used for flying but they are made differently. What type of structure is this?

• Homologous structure

• Analogous structure

• Vestigial structure

• Fossil structure
