Fossil Evidence of Evolution

The chart identifies the geologic time periods when certain animals first appeared. 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?

• Devonian rocks are too old to contain amphibian fossils.

• Finding fossils of any kind in rocks from the Devonian period is unusual.

• Devonian rocks would not contain mammal fossils, because mammals appeared in later time periods.

• Mammal fossils and amphibian fossils will not be found in Devonian rocks, because the two types of animals live in different habitats

What type of evidence is this picture show

• Fossil

• Geography

• Embryology

• Anatomy

• DNA

Answer explanation

The picture shows a fossil, which is the preserved remains or traces of ancient organisms. Fossils provide crucial evidence for understanding the history of life on Earth, distinguishing them from other types of evidence like DNA or anatomy.
