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
