Unit 7.3 Review | 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

Which layer is the youngest

• 1
• 2
• 3
• 4

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

Similarities in bone arrangements, like those in the picture, support the hypothesis that...

• these organisms are not well adapted

• these organisms share a common ancestor

• these organisms all share the same DNA sequences

• these organisms are members of the same species

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

What is this an example of?

• Homologous structure

• Analogous structure

• Vestigial organs

• Functional adaption

The picture shows a/an ___________

• homologous structure

• vestigial structure

Structures are similar in appearance but not in structure

• Vestigial 
• Homologous 
• Analogous Structures 
• Embryonic 

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

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

Study of embryos of various organisms to show a common ancestor because of similarities in development

• natural selection
• embryology
• speciation
• evolution
