Detailed explanation-1: -Human Evolution Scientists who study early humans depend on fossil evidence to help them sort out how our ancestors evolved over time. When looking at the fossils, scientists look for clues to changes in different characteristics such as brain size, skull shape, locomotion, and jaw size.
Detailed explanation-2: -Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species.
Detailed explanation-3: -Evolution – change over time. It is the process by which modern organisms have descended from ancient organisms. Current scientific facts, observations and hypotheses all combine to create current evolutionary theory – which is a well-supported, testable explanation of the biological diversity on Earth.
