Evolution Evidence

The fossils buried in layers near the surface tend to be younger than fossils in layers of rock well below the surface. This is an example of what type of evidende of evolution?

• Fossil record

• Molecular record

• Artificial selection

• Anatomical record

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

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

If modern organisms have a lot of homologous structures, what inference might paleontologists make about those organisms?

• They are reptiles
• One organism evolved from the other.
• The organisms have a common ancestor

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
