Back

They provide evidence of changes between species over time.

Front

How do homologous structures provide evidence for evolution?

Front

A scientist studied sedimentary rock samples from the Devonian period. He claimed he found mammal fossils mixed with amphibian fossils.

Which response to the scientist’s claim is most supported by the chart?
