Detailed explanation-1: -DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
Detailed explanation-2: -How do scientists use anatomy to obtain information about the evolutionary history of organisms? They compare organisms’ anatomy and look for shared traits. All arthropods, a group that includes spiders, insects, lobsters, and many other species, inherited which of these from their common ancestor?
Detailed explanation-3: -Fossils. 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.
