Answer:
in explanation
Step-by-step explanation:
1. fossils show our past ancestors and what we would have looked like before
2. you can use trace fossils (fossils left by an organism) to see how they lived and you can track how they lived their daily life
3.Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. 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. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.
