C6L3: Biological Evidence of Evolution Review

Structures are similar in appearance but not in structure

• Vestigial 
• Homologous 
• Analogous Structures 
• Embryonic 

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

• natural selection

• homologous structures

• Charles Darwin

• the fossil record

Similar structures with different purposes found in different species are known as _____

• vestigial structures

• DNA

• homologous structures

• the fossil record

The changes of species over time

• Embryonic 
• Natural selection 
• Mimicry 
• Evolution 

The picture shows a/an ___________

• homologous structure

• vestigial 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

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

If two organisms have similar traits of DNA they are probably

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