Detailed explanation-1: -Fossils provide solid evidence that organisms from the past are not the same as those found today, and fossils show a progression of evolution. Scientists determine the age of fossils and categorize them from all over the world to determine when the organisms lived relative to each other.
Detailed explanation-2: -Scientists often compare fossils of extinct organisms with living organisms to help determine evolutionary relationships.
Detailed explanation-3: -Biologists often compare the sequences of related genes found in different species (often called homologous or orthologous genes) to figure out how those species are evolutionarily related to one another.
Detailed explanation-4: -The fossil record provides evidence for when organisms lived on Earth, how species evolved, and how some species have gone extinct. Geologists use a method called radiometric dating to determine the exact age of rocks and fossils in each layer of rock.
Detailed explanation-5: -Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
