Evidence of Evolution Review

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

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

What does Darwin's theory of evolution suggest?

• species change over time
• extinct species are not related to living species
• different species can interbreed
• animals that look alike are most closely related

When all of the organisms of a species have died it is called

• evolution
• extinction
• adaptation
• natural selection

Predict which moth would increase in population

• light 
• dark

Scientists compare organisms' DNA to support the theory that all species share a common _________________

• separation
• ancestor
• population
• environment

Structures are similar in appearance but not in structure

• Vestigial 
• Homologous 
• Analogous Structures 
• Embryonic 

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

• vestigial structures

• DNA

• homologous structures

• the fossil record

The picture shows a/an ___________

• homologous structure

• vestigial structure
