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 how life forms present today are different than those from the past

Fossils show that some species have gone extinct

Different sedimentary rock layers provide evidence for how the environment has changed over time

Asemmisa {{asɛmmisaAhyɛnsode}}

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

Separation

Population

Ancestor

Environment

Asemmisa {{asɛmmisaAhyɛnsode}}

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

Vestigial structures

Homologous structures

DNA

Fossil record

Asemmisa {{asɛmmisaAhyɛnsode}}

Structures that were used in ancestral species but no longer used in modern species are known as...

Vestigial structures

Homologous structures

DNA

Fossil record

Asemmisa {{asɛmmisaAhyɛnsode}}

Which is not evidence for evolution?

many animals have homologous structures due to common ancestry

We can observe changes in life forms by observing the fossil record

Many animals have vestigial structures from an ancestor

All of these are evidence for evolution
