Evidence of Evolution

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

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

• natural selection
• embryology
• speciation
• evolution

If two organisms have similar traits of DNA they are probably

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

Structures that look similar but have different functions.

• 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

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

• Fossils show that some species have gone extinct
• Fossils show how life forms today are different than those from the past

Vestigial structures

• Body parts with a different structure with a similar function

• Structures that no longer function in a living thing

• preserved remains of an organism

• Body parts with a similar structure with a different function

Structures that look similar in appearance, but have different functions. 

• Homologous 
• Analogous 
• Vestigial 
• DNA
