Evidence of Evolution

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

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

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

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
